Ajax EN54 FireProtect (VAD) Jeweller

FireProtect (VAD) Jeweller is a wireless visual alarm device (VAD) that complies with the European fire safety standards EN 54-23 and EN 54-25, as well as the Radio Equipment Directive RED (2014/53/EU). The device uses Ajax's robust Jeweller radio protocol, providing a reliable and secure connection to the EN54 Fire Hub control panel or via Fire ReX.

Visual alarm (VAD)

• The device gives a visual alarm via an LED frame that flashes in a 90 ms on / 1,910 ms off pattern, with a cycle period of 2,000 ms (0.5 Hz).

• Particularly suitable for noisy environments or areas with limited audibility, such as wide corridors, large halls and ice rinks, or for ensuring the safety of people with hearing impairments.

Audible signal

• The VAD relies on visual signalling and has no audible alarm (unlike the Sounder/VAD model).

Communication and security
