5G Alarm Diallers

Our GSM Alarm Diallers are connected directly to multiple CPaaS services. With connection to multiple networks and hourly testing by the cloud for the life of the unit, this is the most reliable alarm dialler available. 

  • No SIM card required
  • Each unit pinged every 4 minutes to check status
  • Credit never expires
  • No disconnection due to inactivity
  • Only pay for calls and SMS used 
  • Text-to-Speech voice calls
  • No monthly fees
  • Dials all numbers at the same time
  • Send SMS to all numbers at the same time
  • The most reliable alarm dialler on the market

The data connection to multiple networks in 170 countries (including all 4 UK networks; EE, Vodafone, O2 and 3) has been prepaid for a decade. Just pay for the SMS and calls you use! There is no risk of SIM deactivation due to lack of use.

NB. There is no dial-to-open on this model. The output relay can only be changed via the Live Screen. For the IoT dial-to-open system see our other products.

Setup is ultra simple. Just scan the QR code to get to the Live Screen and start adding numbers! 

If my dialler stops working how would I know?

The 5G IoT networks, particularly NB-IoT, offer connectivity deep underground and inside buildings. They work where mobile phones do not work. The network sends the data to the dialler 2048 times so the dialler can determine the data from the background noise where there is barely any received signal. This is how the 5G dialler achieves such high levels of sensitivity. The downside? It's a slower. Messages can have up to a 1.6-10s delay. 1 bar on your phone outdoors will give almost full signal on NB-IoT.

Where the signal is better the dialler will use the high speed Vodafone or O2 LTE-M network. Finally, where no 5G networks are available, the dialler will fall back to 2G.

It's worth noting we discontinued our 2G, 3G and 4G diallers because they're the wrong technology for dialler applications. Use a 5G dialler. It's the correct choice. There are no VoLTE or IMS issues with the iot-portal diallers.


The Alarm Dialer is ideal for use in Burglar or Fire Alarms as a universal fit cell phone GSM Auto-Dialer/SMS Message Sender with email. With 4 inputs both the intruder alarm bell and set/unset status can be monitored.

Similarly, on fire panels the fire alarm bell and fault output can be monitored. By default, alarm activation on input A triggers SMS messages and telephone dialling (messages are read out during the call). Set/unset or fault activation on input B triggers emails sending which is free.

All setup is done online using a PC or smart phone. Each messages can be fully customised using the online portal. Basic programming can also be performed by SMS.

Every 4 minutes the unit is contacted by our server to ensure it is functioning correctly. Any critical faults found are sent to the master user by SMS and email.

Service charges on all 4 UK networks (and 100+ international) prepaid for 10 years (current service charge for an additional decade is £20). 

Can be programmed and controlled via SMS and email in addition to the PC/Smart Phone. 

Outside of your allowance, calls and text messages are charged at a flat rate worldwide as follows:

Can I use my own SIM? No this is not possible. We don't recommend using mobile phone SIM cards in alarm diallers.
