wLSN Smoke Detector
(ISW-BSM1-SX)
Under normal conditions, the red LED on the wLSN Smoke
Detector flashes once every 8 sec while the sensor monitors the
surrounding environment. When the sensor detects smoke, the
LED changes from flashing to steady and the sounder produces
a loud continuous tone. Refer to Table 5.20, Page 46, and
Table 5.21, Page 46.
A self-diagnostic feature monitors detector sensitivity and
operational status.
A cover tamper switch transmits a tamper signal when the
cover is removed from its base.
The optical chamber is removable for easy maintenance.
The detector complies with EN14604.
