Total control from virtually anywhere with the GSM Remote Switch Control GMT-RC11. A simple telephone call (or text message) can remote switch any electrical device on or off and also open or close a gate or door (entry system) - and that call is free.

Any call from an authorised user's number is recognised by the GMT-RC11 Remote Switch causing it to promptly drop the call and carry out its selected action. It can, if required, send a confirmation signal that the command has been received and actioned. Acting on the research from our customers and users, GM Techtronics Ltd has commissioned a brand new range of GSM products, paying particular attention to the monitoring of these devices.

They can be operated from almost anywhere in the world by making a no charge call from an authorised number stored in its memory. The GMT-RC11 is the first product in our new range to be released. It is a basic but clever entry level GSM remote switching device that was designed for easy programming, quick installation and simple operation for the end user. Providing a basic - normally open or normally closed - relay remote switching device.

The GMT-RC11 is supplied with a small antenna, other antenna options are also available.

This device has a standard SIM card socket allowing the installer or user to select the best service provider for the location where it is to be installed. It's single output relay can be used for operating gates, barriers, door entry system, resetting electronic equipment - or virtually any electrical device - from almost any phone anywhere in the world.

Installing and programming the device could not be easier. Remote programming can be carried out if required using SMS messaging.

There are unending uses and possibilities for this product, if you just need to simply turn something on / off or open and close remotely over the GSM network then this product is for you.

Gate Automation

Please select what type of automation you require for your gate/s. Double & Single Swing refer to motors which attach to the gate and pillar of a swing motion gate. Double & Single Underground refer to motors which lay beneath the ground which attach to the hinge end of swing motion gates. Choose Sliding if you require lateral moving gate automation and Wheeled if you require a motor which utilises a wheeled motor to drive your gate/s.

Motor Voltage

There are two types of power outputs to consider - 24v & 230v. If you need a higher number of operations (opened/closed more than 5-6 times in an hour) during peak periods such as the morning and evening, then you may wish to consider a 24v system.

24v systems are more suitable for higher operation levels as they tend to run cooler than 230v gate motors. However, they do cost more in relative terms, so if you only need to open or close the gate 1-5 times an hour then a 230v system might prove more cost-efficient.

24v motors tend to be used on commercial premises, whereas 230v tend to be used on standard domestic properties. The exception to this rule is sliding gate motors where the reverse is true - 24v sliding gate automation systems tend to be for domestic use, 230v for more intense use (commercial/communal).

24v systems can draw power from battery backup systems meaning they can still operate during any mains power cut (a 230v or 3 phase system would need to be opened with a manual release key).

24v systems can also utilise solar power units as a means of charging batteries, allowing you to site gate automation in rural and remote locations where mains power is unavailable.

Specifications can be found for each product from their datasheet. Each datasheet is downloadable from each product page on this website.

Weight of Gate

All electric gate motors operate up to a maximum weight. This is so the gate will operate in a reliable and safe manner. It is essential to know the weight of each gate leaf in order to choose the correct motor for you installation. If you do not know the weight of your gate/s, send us a photo along with the gate/s dimensions and we can advise.

Gate Width

As with weight, gate motors are designed for gates within certain dimensions. The most important dimension is the width of the gate. To ensure you select the right motor to operate your gate you must know the width of each gate that requires automation.

Opening Angle

Each motor has a maximum angle to which it can operate to. Therefore it is important to note how far the gate needs to open in order for a vehicle to enter/exit safely.

Daily Use

The amount of times your gate is used per day is a determining factor when deciding on the right motor for your usage. Motors are designed to operate within a certain capacity (operations per day) so choosing a motor compatible with your desired use is essential for its durability. Select from the options below the number of times (open & closure = 1 x operation) the gate/s will be operated on an average day.
