WSD505 W IRE LESS SMO KE DET EC T OR (AEC 200
SERIES)
The Alpha Communications® WSD505 W ireless Smoke Detector
is for us e with the AlphaEcall™ 200 series (AlphaECall200)
Wireless Emergency Call System.
Th e W SD505 is built upon photoelectric ESL technology, that
continually monitors its own sensitivity and operational status.
The detector provides drift compensation and visual display of
over- or under sensitivity so that corrective action can be taken
to reduce false alarms. Wireless frequency hopping technology
maximizes range and reliability. The W SD505 is powered by two
(2) included 3V Lithium batteries, and battery life is estimated at
up to five (5) years, reducing the inconvenience and cost of
replacing batteries. The WSD505 Wireless Smoke Detector
features a low profile design and blends in with any decor.
