Frequently asked questions
Smoke detector or heat detector?
A smoke detector (Smoke) responds to smoke particles and is suitable for most rooms. A heat detector (Heat) responds to temperature and is better for dusty, smoky or steamy rooms such as kitchens, garages or technical rooms.
What does the Sounder variant mean?
With a Sounder variant, the detector itself contains a siren (85 dB, EN 54-3), so that the detector also sounds an audible alarm directly.
What do the EN 54 standards mean?
EN 54-7 = point smoke detector, EN 54-5 = point heat detector, EN 54-3 = fire alarm sounder, EN 54-25 = wireless components.
Do I need a Fire Hub?
Yes. The detectors are controlled by the Ajax EN54 Fire Hub and are not compatible with a standard Ajax hub.
