Covert Battery-Powered 3G GSM UltraDIAL Door & Pressure Mat Alarm

A discreet and reliable security solution, the UltraDIAL 3G GSM Wireless Door/Window & Pressure Mat Alarm silently alerts up to three key-holders via phone call and SMS when triggered. Supplied with two magnetic contacts, one pressure mat, and a remote control, this system is ideal for protecting doors, windows, and entryways without drawing attention.

How It Works

• The kit includes a battery-powered UltraDIAL GSM Alarm, 2 magnetic door/window contacts, and 1 floor pressure mat.

• All devices connect wirelessly, forming a secure private network.

• The system is armed and disarmed simultaneously using the supplied remote control.

• If a door/window is opened or someone steps on the pressure mat while armed, the alarm is triggered.

• UltraDIAL remains hidden (battery-powered, no wiring required) and secretly notifies up to 3 pre-programmed key-holders by phone and SMS.

• Unlimited extra door contacts, PIR sensors, or mats can be added.

Communication

• Uses the mobile phone network (standard-size SIM card, PAYG or contract).

• Alerts up to 3 key-holders with:

  • Phone calls (with your 30-second pre-recorded message).

  • SMS text alerts (optional per setup).

• Optional roaming SIM cards available for stronger UK coverage across all major networks.

Applications

Perfect for discreet protection of:

• Narrowboats (contacts on doors, mat hidden under carpet).

• Workshops, sheds, or garages (UltraDIAL hidden out of reach).

• Static caravans (contacts on entry doors, mat by main access point).

• Multiple buildings (100m wireless range, 40–50m in practice).

System Expansion

• Silent Detectors: Wireless door contacts, pressure mats, or UltraPIR sensors (silent mode).

• With Sirens: Add indoor battery sirens, outdoor solar/battery sirens with strobe, or PIR sensors with/without hoods.

Arming & Disarming

• If powered by 5V supply, can also be armed/disarmed by SMS command.

• Built-in 30-second exit delay for convenience.
