Battery-Powered Covert GSM UltraDIAL Alarm with 2 Outdoor BT PIRs

The UltraDIAL Standalone 3G GSM Alarm is a discreet, battery-powered IP66 weatherproof alarm supplied with two wireless outdoor PIR motion detectors (each with a built-in 130dB siren) and three remote controls.
When triggered, the system silently notifies up to three key-holders via phone call and SMS, while the PIR sirens activate on-site.
Perfect for scaffolding, boats, workshops, sheds, garages, or temporary security needs.

How It Works

• The kit includes a battery-powered UltraDIAL GSM dialler and two outdoor wireless PIRs with 130dB sirens.

• Devices connect wirelessly in a secure private network (up to 100m range).

• Arming and disarming is done simultaneously with any of the included remote controls (up to 9 supported).

• If an intruder is detected:

  1. The PIR silently triggers UltraDIAL.

  2. UltraDIAL secretly contacts key-holders by phone and/or SMS.

  3. Both PIR sirens activate at 130dB for maximum deterrence.

• Additional PIRs and sirens can be added (unlimited). All activate together when triggered.

• UltraDIAL should be hidden or locked away to stay covert—its wireless, battery-powered design makes this easy.

Applications

• Scaffolding – PIRs strapped in place with cable ties, UltraDIAL hidden away.

• Workshops, sheds & garages – PIRs inside, UltraDIAL stored out of reach.

• Boats – PIR mounted under canopy, UltraDIAL hidden below deck.

• New builds or renovations – Protect sites before they’re weatherproof.

• Exhibition stands & shows – Quick, temporary, and effective security.
