ISW BSM1-SX WLSN SMOKE DETECTOR

The wLSN Smoke Detector is a non-latching wireless detector that transmits alarm signals to the wLSN Hub using the wireless Local SecurityNetwork (wLSN) protocol.

Functions:

Alarm Mode

When the detector goes into alarm mode, the detector's built-in sounder turns on steady and an RF signal indicating the alarm condition is sent to the wLSN Hub. The Hub signals the control panel identifying the specific detector in alarm. Alarm conditions are non-latching so if the alarm condition goes away – smoke dissipates – the detector returns to normal. The photoelectric smoke detector acquires ambient obscuration data every 8 seconds. The red LED blinks every time a sample is taken. If any one sample is above the calibrated alarm threshold, two more samples are taken at 4-second intervals. If all three samples are above the calibrated alarm threshold, the detector goes into alarm mode. 

Status Indicator 

The LED and sounder indicate the status of the detector but not of the RF signaling circuitry. Refer to the wLSN Reference Guide (P/N: F01U009440) for details.
