Fire Alarm Monitoring 4G SMS Lite

The SMS Lite is used for commercial fire alarm system monitoring.

Defend Fire group is an Australian company specialising in all types of fire alarm monitoring, fire detection and suppression systems. Many of their systems are installed in the remote rural communities of Darwin, Alice Springs and Adelaide.

Having a reliable and proven messaging capability is crucial for these applications – it provides advance warnings, power supply monitoring and reduces travel times and costs. The SMS Lite has four inputs and two relay outputs to give maximum flexibility to monitor status and operate remote equipment via your phone.

The function of the relays in the alarm panel is usually programmable for conditions including alarm has been triggered, mains power loss, tamper detection/panel open etc.

The SMS Lite is configured by text messages and secured with a unique PIN.

The SMS Lite inputs have a programmable “debounce” time to help prevent nuisance messages being sent, when activated.

With the 3G cellular networks closing, and the 4G networks being available in many rural locations, the 4G SMS Lite should be the first choice messaging system.

Please remember, the old 3G cellular networks are closing – some have already closed.

Any existing monitoring devices on that network need to be replaced now.

Generator remote start

The QTech SMS Lite is used to remotely start and monitor your generator via text messages over the 4G cellular networks.

Starting your generator is now as simple as sending a text.

We have been involved with a generator remote start project for the popular Kubota GL600D-AU-B genset fitted with the DSE 4520 digital control panel.

The generator remote start ability was of crucial importance for the customer. Milne Bros, the local distributor was contacted for assistance. They evaluated the compatibility and interface wiring prior to the customer purchasing the genset.

DATRAN Australia and QTech in NZ were involved in the discussion to ensure the customer could achieve remote starting using text messages.

The Kubota GL600D-AU-B genset has many great features. It was selected as it has quiet running, efficient fuel use and an auto change over for when the mains power drops out.

More information of the Kubota GL600D genset can be found here.

The SMS Lite interfaces to the DSE 4520 control panel – Input A, pin 14 is wired to the SMS Lite output relay RLY1. Sending a text message to the SMS Lite closes the relay and activates pin 14 (connects it to ground) remotely starting the genset.

Genset Kubota GL600D remote start

The SMS Lite’s low power relay outputs are ideal for this type of electrical switching.

More details on the DSE4250 control panel, including the wiring diagram and I/O configuration options is available here.

The genset also has multiple outputs that can be monitored by the SMS Lite and used to send text messages to notify you. Typical example would be the genset has started as the mains has dropped out.

Want to know more about how we can help remote starting? Please get in touch now.

There are many different types of generators available, but you need to ensure that yours has a suitable electrical interface for remote starting.

Remote start kits provide the electrical interface to the necessary start button, kill switch etc. They can be a factory fitted option, pat of the control panel or an aftermarket accessory. Please contact your provider with this note.

SMS Lite – Relay Output Options

The SMS Lite relay outputs can be turned on, off, pulsed for 1 second or pulsed for a configurable time. This is useful as the generator’s remote start interface may need an activation signal for several seconds before operating. Some generators also have separate start and stop inputs.

SMS Lite – Input Switch Debouncing

Input switch debouncing is also a good idea and will prevent false alarms and help reduce the quantity of SMS/texts sent. Debouncing is configurable, it’s a global setting so applies to all four inputs.

Low Voltage Warning

The SMS Lite automatically sends you a text message if the supply voltage drops to 10.5V DC. When voltage increases to 11.5V DC a confirmation text will also be sent.

Fuses and Relays

Remember to install suitable fuses in the interface wiring.

A DC supply isolator switch for the SMS Lite should be installed if the device will be unused for extended periods or powered from the generator’s starter battery.

We recommend installing interface relays on the output side of the SMS Lite controller. This assists future serviceability and allows high current/voltage operation. The SMS Lite relays are rated at a maximum of 2A at 32V DC only.

For more information on interface relays please click here.

For further details, refer to the SMS Lite user manual.

Antenna Selection and Mounting

We have a range of cellular antennas available.

Please remember to mount vertically and away from conductive poles etc.

Please get in touch to discuss your application.

The 4G SMS Lite is the first choice for Generator Control using SMS.

Cybercrime is increasing

Cybercrime is increasing in Australia – The targets of Cyberattacks now include automation systems, industrial networks, and farms. Each of these has an increasing amount of internet connected technology. For farms, everything from tractors to milking platforms to soil moisture sensors are connected to the internet and may have some level of vulnerability.

The good news is there are simple steps you can take to improve your online security and system protection.

Firstly, we advise you to visit the governments’ ASCSS website.

The ASCSS recommended suggestions and minimum steps include:

• Always apply patches and updates

• Always back up your data frequently

• Consider two factor authentication 2FA or multi factor authentication

• Train or remind staff to look for suspicious emails/texts.

• Ensure your modem/devices do not have the default password.

• Make a plan. It is easier to think about all the consequences of the situation now, rather than during an attack. Remember to consider all your automation and connected systems when considering a plan.

• Reset your devices before selling or disposing of them.

• Stay informed.

Sign up for the free alert service to keep ahead of the current attacks.

It is a good idea to use these alerts as part of your regular team or staff updates to improve resilience.

The Australian Federal Police also have a good selection of resources:

I think this quote from the AFP sums it up nicely:

“One of the best tools we have for fighting cybercriminals is you.

We need every Australian to understand different types of cybercrime and the simple steps you can take to avoid becoming a victim.”

Crane aviation obstruction lights

Aviation obstruction lights, or “aircraft warning lights” are vital warning devices. They help pilots avoid tall obstacles such as cranes, particularly when visibility is reduced or during the night.

Tall construction cranes encroaching into controlled airspace is a serious business and strict rules apply.

Knowing that the aviation obstruction lights are both running and the power supply is operational are therefore crucial aspects to monitor on tall cranes.

Crane Aviation Lights SMS Lite

The popular 4G SMS Lite has now been evaluated by a large Australian crane company.

Their requirement was to provide notifications to multiple staff over the 4G cellular networks, and for the system to be easily installed to the current crane fleet. The client also needed an additional feature to “broadcast” an alert to multiple cell phones and not wait for the usual escalation period. QTech worked with the client to develop this feature, which is now available in firmware v4.08.

Getting automatic notifications when the crane is in use or powered up is another benefit of using the SMS Lite. Connecting one of the digital inputs to the “live” or “run” signal in the control panel will confirm the customer is using the crane – particularly useful for lease and hire contract monitoring. Should it be necessary, the crane could be inhibited remotely by activating one of the relay outputs.

Selection of the aviation obstruction lighting is a complex task which will need expert involvement to ensure it meets compliance requirements and local conditions.

Some of the considerations for tall cranes and aviation obstruction lights include:

Typical crane heights of up to 45m and 105m need aviation warning lights and may need multiple sets of lights at different heights and mounting alignments. The general requirement for construction cranes at night includes a maximum permitted height of 274 m.

The flash rate, the colour and the intensity of the LED lights can vary and differ by region and application:

Flash rates: 20, 30, 40 or 60 flashes per minute?

Flash duration: 200ms flash duration or on all the time?

Light colour: red only, white only, red and white or is infrared required?

Flash intensity: 32.5 candela, 200 candela, or 2000 candela?

The 4G SMS Lite can be installed in any remote location if there is good 4G cellular coverage.

We have a selection of alternative antennas for weak signal areas and low profile options.

The SMS Lite is suitable for solar powered installations and it can automatically text you with the power supply voltage.

Please contact the team to discuss your monitoring requirements.

LED lighting upgrades - remote control

LED lighting upgrades for sports fields are becoming more popular.

Our low power wireless controllers are ideal for remote control of these LED lights.

LED lighting has multiple benefits over incandescent lighting, including lower energy consumption (lower power costs) and longer life expectancy.

Importantly, many of the modern LED lighting fixtures are modular and allow the lighting intensity to be changed to suit the match or event.

The requirements for sports field illumination varies depending on the sport being played.

Typical illumination levels required include:

Recreational: 300 lux

School/amateur: 500 lux

Professional: 1000 lux

International (FIFA/world cup): 2000 lux

But how can the LED lighting intensity be remotely controlled without digging up the pitch or replacing the control cables?

Our Wireless Point to Point (WP2P) and Multi Point Controller are popular solutions and have been specified for the remote control of LED lighting upgrades at several rugby fields recently.

LED sports field lighting

The WP2P modules have three output relays, and these can be interfaced into the LED lighting control circuit. From a central control room or the ground keepers’ office, a switch is activated to change the LED lighting intensity via radio.

The WP2P also has input options that can be used to monitor lighting module failure, power failure or even a tamper switch in the control panel.

Typical interface wiring includes:

TLM Water Tank level monitor

Water tank level monitoring made easy.

The TLM is a solar powered IoT system using low power LoRa radio communication.

Our web-based dashboard technology provides you with tank level information and alerts for both critical water levels or significant rates of change.

The system doesn’t need cellular coverage and the robust antenna helps gives a range of many kilometres between the tank and the gateway.

Set up and configuration is easy thanks to a “self service” website. Alerts are configurable and can be sent to multiple people via SMS/text, email or push notifications.

The TLM is suitable for water tank level monitoring on farms, industrial sites as well as lifestyle blocks in semi-urban areas.

Water tank level monitoring made easy

Please click here for a demo on the Water-Insight website.

Installation of the TLM is straightforward.

The installation and set up instructions are available here.

The TLM uses our sophisticated and proven, IMS cloud technology to show you the water tank level, status indicators and water usage statistics.

The TLM uses LoRa IoT communications from the water tank to the gateway – the gateway then plugs into your existing internet connection.

You can also share the water tank level data with other farm staff or organisations that you given permission to. They can also be configured to only receive specific alerts and alarms.

DATRAN Australia also provides cellular and wireless remote control systems.

Our popular SMS Lite and 900MHz Wireless point to point are available here:

Wireless remote control systems

Farm backing gate controls

Backing gates are slow moving motorised barriers that control the dairy herd movement into milking platforms.

The motor drive units used are often water powered devices. Using water removes the need for long cable runs and the water also helps with the yard clean up.

A recent enquiry needed to add remote valve control to an existing water powered backing gate. No electrical supply was available for the valve control system and the control buttons needed to be in the dairy shed control panel.

The popular low power Wireless Point to Point (WP2P) systems were utilised.

Solar power was provided from our versatile RSS01 solution.

The solar supply provides power to the WP2P module and powers the latching solenoid on the water drive unit. The solenoid controls the water flow to the drive unit and uses the QTech LSD01 latching driver. Reliable radio communications is provided by our industrial grade antennas, including low profile options at the backing gate.

DairyNZ recommends these considerations for backing gate control options:

  • Install an audible alarm or buzzer to sound when moving. The buzzer could be integrated into the RSS01 solar enclosure.
  • Limit backing gate movement to a maximum of five seconds to prevent animal discomfort and stress.

The DATRAN Australis items required for this project were:

Qty 1x PD8810E-WP2P       Digital 900MHZ Wireless Point to Point Pair                  

Qty 1x PD9241                 900MHz 3dB Fiberglass Whip antenna                      

Qty 1x PD5414                    Power Pack 230V AC Input, 13.8V 250mA Output                                                

Qty 1x PD5801                    RSS01 Solar Station (Solar panel, case, invertor, 12V battery, mount)                 

Qty 1x PD9245                    Cellular Multiband Low Profile Antenna         

Qty 3x PD5811                    Latching Solenoid Interface LSD01                                                                      

We have previously supplied another backing gate control solution for electrically powered systems.

This solution utilised the Q48 P2P.

The Q48 P2P was selected as six digital outputs were needed to be controlled from the dairy shed.

The Q48 P2P was retro installed into an electrically powered backing gate system, as the existing control cable was becoming unreliable. The replacement cost of the cabling was high, but the likely downtime during the milking season was prohibitive for the farmer.

The existing waterproof pendant control was also reused in the wireless Q48 P2P system, which helped the dairy operators.

Please get in touch.

We will help you select the best solution for your backing gate control requirement.

Latching Solenoid remote control

We were approached to provide a control solution for remote latching solenoids over a distance of 1200m.

Latching solenoids are commonly used in the irrigation market as they are very low power.

Latching solenoids require a special driver circuit which controls the polarity of the switching signals.

Latching solenoid control can easily be achieved with our WP2P system and a LSD01 latching solenoid interface to manage the polarity switching.

This previous post details a simple on off remote control of a latching solenoid.

However, this enquiry needed a system to interface to the existing irrigation controller.

The irrigation controller’s output was already for a latching solenoid – so how do we transmit that over more than a kilometre?

A novel system was prescribed to convert the latching output to a relay closure, then transmit the relay status, and then convert it to latching at the solenoid end.

The solution used both the QTech LSD01 and the IPC relay module, usually used for solid set irrigation projects.

The WP2P systems’ relay outputs are momentary operation from the connected input switches. However they also have a “fail safe” option allowing you to select what happens if the communication link goes down.

If you need control for remote latching solenoids or remote control of valves – with or without latching relays – please contact us for assistance.

For those interested, an “H bridge” circuit is usually used for solenoid polarity switching.

Harbour Buoy lighting control SMS Lite

The international standards and conventions for maritime buoys is a complex and massively confusing topic, even for seasoned sailors.

Whilst we cannot simplify the standards, DATRAN Australia can help provide remote control of the harbour buoy lighting, using text messages over the 4G cellular network.

A customer in Queensland has recently selected our SMS Lite for it’s buoy lighting control.

SMS Lite

Remote control is especially important with solar powered buoy lighting systems. Energy conservation is crucial for these systems to ensure that the lighting is always available when needed.

The SMS Lite is low power and ideal for being solar powered. Features include pulsed outputs, input debouncing and an automatic low voltage alert.

DATRAN Australia also offers fully packaged solar powered systems for both the SMS Lite and the popular 900MHz Wireless Point to Point (WP2P) radio systems.

This fascinating article outlines the complexities of international buoy lighting conventions.

The SMS Lite is widely used in Australia, not just for harbour buoy lighting control. The most popular applications include the remote starting of generators, flood detection warning systems and holiday home heating control.

More details of these applications and projects can be found here.
