Externally-visible LED indicates smoke detector status
▶
Supervised for low-battery and detector head removal
conditions
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.
Test-Silence Button Operation
A Test-Silence Button allows performance of sounder and
sensitivity tests and silencing of alarm sounder and trouble
chirp. Refer to the wLSN Reference Guide (P/
N: F01U009440) for details.

Installation/Configuration Notes
Compatibility Information
The wireless Local SecurityNetwork (wLSN) including the
wLSN Smoke Detector is compatible with the Easy Series
Control Panel.
Mounting Considerations
Mount smoke detectors on interior ceilings preferably at or
near the center of the ceiling. Where mounting in the center
of the ceiling is not practical, mount on the ceiling no closer
than 10 cm (4 in.) to walls or corners or on an inside wall
between 10 cm (4 in.) and 15 cm (6 in.) from the ceiling
near the middle of the wall.
Note Do not mount smoke detectors on drop ceiling
tiles. Mount to a metal runner. Since
installation on metal surfaces can affect the RF
propagation pattern of the radio transceiver,
verify the suitability of the installation site
using the wLSN Installation Tool before
detector installation.
The RF transceiver has a range of approximately 1000 m
(3000 ft) in open air. However, in normal operation, the
actual RF range depends on building construction.
