The GSM/WiFi Alarm Dialer is designed to allow 2-way communication from your Honeywell ADE Accenta Alarm panel and your mobile phone. The GSM version communicates using the mobile network allowing you to monitor your alarm remotely without a telephone line. The WiFi version uses your home/business internet to communicate and call/message you. 

  • Small size allows installation within alarm panel
  • Pre-wired for quick and easy installation
  • SMS message can be customised
  • Arm and Disarm using remote keypad on smart phone
  • Ultra simple programming and set up
  • Dials, send SMS messages
  • Full keypad access using web browser

    Calls and texts are made and sent to multiple numbers when the alarm sounds or (optionally) when the alarm is set and unset. All numbers are called and messaged at the same time. The text message can be changed and is read out during the phone call.

    Using a web browser on a phone or PC you have access to the keypad as if you were using the keypad on site!  

    The GSM version comes complete with an any network PAYG SIM card. £1.99 is deducted from your balance each month for SIM card connection data costs. The WiFi version does not require a SIM card as it uses your internet to connect to the network. There is no monthly charge for this unit. You can top up your balance via the keypad screen in increments of £5, £10 or £20 using Paypal.

    SMS and calls are charged at £0.15 for each call and message. 


    Please note some features are not compatible with older G3 alarm panels. This will function perfectly as a dialler/SMS sender and you will be able to send individual key presses to the panel. However, the G3 panel does not output any text to the screen and does not provide a suitable SET output for this dialler. This is a limitation in the older G3 alarm panels and not the dialler.


    What is a Cloud Dialler?

    Why do we provide a SIM for GSM Diallers?

    We've been making alarm diallers and supporting them for 10 years so we've learned a lot about the pitfalls of using mobile SIM cards to keep your alarm connected. There are many long term reliability problems using ordinary mobile phone SIM cards which are designed for phones and not always-on security equipment.

    PAYG SIMs are ineffective in alarm diallers primarily as they will not be able to warn you when they run out of credit or, as is more common, they are disconnected because the minimum top up requirements have not been met. Most support calls we receive are traced back to a problem with PAYG SIM cards. The data is also very expensive with a PAYG SIM.

    Contract SIMs are better in alarm diallers as they're likely to prove reliable so long as the bill is paid. However, even the cheapest contracts are unnecessarily expensive when they're not likely to be used very often. They also restrict you to just one network which compromises the reliability of your equipment. We frequently find localised cell faults on one network stopping our diallers working; a problem that doesn't occur using a roaming IoT SIM.

    We've been able to make use of a new class of 'IoT' SIMs with our latest generation of alarm diallers.  They can roam on any available GSM network so are not restricted to one provider unlike a mobile phone SIM. As they have no number we use a data connection directly to our telecoms provider to send the messages and make the call. Calls can be made to all numbers at once as it is not the individual dialler doing the calling and messaging. There is also the added advantage that the message can be read out during a call. Once the dialler is triggered it can be destroyed by an intruder and you will still receive a call as it's not the dialler physically making the call.

    We work on a PAYG basis and can de-activate a SIM temporarily and can re-activate it later. We're able to support diallers with our SIMs a lot better as we have full access to your individual connection from SIM to dialler. Our SIMs can roam on any network vastly increasing their reliability. We can even pick and chose which networks they can use if there is a problem with one of your networks locally.

    Of course the major benefit is that we do not cut you off without telling you the moment your credit expires. If your balance is negative, you will automatically be sent an SMS and email telling you - something a dialler cannot do if its mobile phone SIM runs out of credit. If you no longer require the dialler or you would like to temporarily stop using it, it's a person that switches off the SIM not just a computer in O2/Vodafone/EE etc... We are notified of negative balances and we will contact you to confirm you no longer require the SIM before switching it off. It makes considerably more sense to let our computer monitor your SIM rather than you manually remembering to check your balance every few months.
