System Design - EMS SmartCell Programming Manual

System design

All installation work should be carried out in accordance with the system design.
Wireless zone monitor (WZM)
230 VAC and 24 VDC powered WZMs are available.
Communication between devices and the WZM is bidirectional and operates in the European harmonised
868 MHz frequency band. The WZM's features are detailed in the 'Controls and Displays' section.
The WZM can be connected to conventional and addressable fire systems. See pages 25 to 26 for wiring
configurations.
Wireless dual smoke and heat detectors
Detectors are available as standalone devices and alternatively with integrated sounders or integrated
sounder and beacons. Their fire detection can be configured for smoke, heat or dual smoke and heat.
Available sensitivities are listed below. When configuring as dual detectors, one smoke and one heat
sensitivity is selected. If either of these settings is reached, the detector will send an alarm condition to the
WZM. The detectors are programmable via the WZM.
Smoke
sensitivities
Normal 58˚c static (A2S)
Normal + AVF * 58˚c rate of rise (A2R)
72˚c static (BS)
72˚c rate of rise (BR)
Wireless fire sounders and beacons
Sounders can be set to high or low volume, whilst sounder or beacons can also be independently
enabled or disabled. The default fire sounder tone is tone 5.
Sounders have 31 tones available, that can be played on the configuration tool for verification.
Available tones are shown overleaf:

remains alarm, before acting on the event.
