EMM-Tek GSM Control Products

RMC301RC - GSM Controller / Alarm

A GSM controller in a rugged extruded aluminium case with the addition of our SuperCap power backup technology.

This is the perfect system for you, if you want to use the power of the GSM network to control or monitor things from a distance.

  • Quad Band GSM enabled - Worldwide coverage
  • Logs Data to onboard non-volatile memory
  • Measure temperature/voltage - 3 analogue inputs
  • Two digital/sensor inputs
  • Set alarms based on inputs
  • Two on-board relays to control external equipment
  • Two additional logic level ouputs
  • Optional GPS capability (tracking, control & alarm)
  • IP65 rating for weather protection
  • Control with SMS messages
  • Can transfer information by SMS or IP push
  • Easily interfaced to PIR and similar sensors
  • Simple DC power supply 5.5V to 30V

The RMC301RC is smaller than previous models and incorporates on-board memory for data logging purposes.

The system can measure signals, control relays, get status updates and control systems using SMS messages. You could even use the RMC301RC to tweet status updates to your timeline. The RMC301RC also has an extended range of GPS commands (useable when an optional GPS module is connected). The firmware offers unrivalled levels of control for GSM based systems. The flexible on-board power supply system means integration is usually very simple.

Typical applications include control of heating, lighting, pumping & ventilation systems. Remote monitoring of buildings & industrial plant. With the optional GPS module, systems may be tracked and alarms created that are triggered by movement or location.

The RMC301RC offers two digital inputs, three analogue voltage inputs, two digital outputs and two double pole-changeover relay outputs.

GPS1- GPS receiver module

This optional plug-in module brings GPS (Global Positioning System) satellite receiver capability to the RMC301. It can be used as a movement alarm, to provide continuous tracking information or even simply to provide highly accurate time stamps for critical events that trigger the RMC301.

Being separate from the RMC301 means that the GPS1 module can be mounted in the most advantageous position for reception rather than being mounted where the RMC301 controller is located.


RMC301R - GSM Controller/Alarm-GPS capable (no case)

The RMC301R is the bare board version of the RMC301RC. It is still fitted with the onboard relays and terminals of the RMC301RC but does not come with the back-up SuperCap power system

The RMC301R has the same capabilities as the RMC301RC but is ideal for building into your own equipment.

Typical applications include control of heating, lighting, pumping & ventilation systems. Remote monitoring of machines and vending systems

This is a bare PCB system (size 55mm wide by 100mm long, max height approx 15mm). Email us or call with your requirements.

RMC301L - GSM Controller/Alarm-GPS capable (no case)

The RMC301L is identical to the RMC301R except that the relays and terminal blocks are not fitted.

£128.50 unit price


RMC301LC - GSM Controller / Alarm Lite

All the core capabilities of the RMC301RC including the extruded aluminium case and the SuperCap power backup technology (externally the RMC301LC is identical to the RMC301RC). However this version does not include either the relays or the screw terminal blocks. (Connections must be soldered to the circuit board.) This is the perfect system for you if you want to use the power of the GSM network to control or monitor systems from a distance. It also make the core of a highly flexible alarm system.

In the event of a power failure the SuperCap power backup will send out warning messages to advise of the power failure. Antenna not included.

RMC121 - SMS Bridge

The RMC121-SMS Bridge allows the user to transfer SMS messages from one or more EMM-Tek SMS based systems (like the RMC301) to the IP world of web servers.

  • Quad Band GSM enabled - Worldwide coverage
  • Ouputs data as GPRS/FTP/UDP/HTTP Push
  • IP65 rating for weather protection
  • Control with SMS messages
  • Can transfer information by SMS or IP push
  • Simple Low power DC supply 5.5V to 30V

In this way, data can be extracted from the most remote and challenging locations, (that probably would not support a GPRS or similar style data link) and be sent to a server based application. The bridge can be mounted in a normal strength signal area which enables the data transfer to happen without signal integrity issues arising.

The on-board control firmware offers screening of incoming messages to ensure that only valid SMS messages are processed. and ignores spam and other SMS messages. The unit needs no external connections apart from power and antenna. Using EMM-Tek’s server side software, data can be stored on an SQL database and used to create tables or charts to display data and maps to indicate the position of GPS enabled units that send SMS data to the RMC121-SMS Bridge.

The RMC121-SMS Bridge is housed in a tough extruded aluminium case which keeps out dust and moisture. It can be powered by a mains adaptor or simple DC supply of 5V5 to 30V. It needs an external GSM antenna. The Quad band GSM radio used by the RMC12-SMS Bridge enables worldwide operation wherever GSM signals are available.


RMC320 Vacant Building Protection

The RMC320 provides stand alone protection for vacant buildings using built in PIR detection and GSM signalling technology. The system does not require either an external power supply or a phone line.

  • More effective and less expensive than manned guarding for vacant property
  • Guard against sqatting & metal theft
  • No mains electricity required
  • No phone line required
  • Uses GSM (mobile phone) network to report status
  • Control by mobile phone
  • Ideal for temporary installations
  • Suited for applications where conventional wired alarm systems would be impractical or too costly
  • Up to 1 year battery life
  • Choice of additional input sensors.

This intelligent system can monitor large indoor areas using its in-built PIR (passive Infra-Red Detector). When triggered by movement or an external sensor, the unit sends text messages to the numbers stored in the system. Additional external sensors (magnetic switch & PIR) may be fitted to effectively cover larger or awkwardly shaped areas. External sensors can also measure temperature or trigger if the building floods. Ideal for protecting vacant property and vulnerable buildings.

Remember; all our products are covered by the 30 day money back guarantee. If you are not delighted by the product, just return it to us in good condition and we will give you a FULL refund.

This is in addition to our one year guarantee against faulty parts and manufacture.
