wLSN Relay Module
(ISW-BRL1-WX)
The wLSN Relay Module allows the control panel to control
external devices through a Form C relay. This module also
provides a supervised point for monitoring external devices.
Refer to
Section 5.4 wLSN Door-Window Contact, page 26
for
device wiring options.
Auxiliary power input terminals are also provided to
supplement battery power when relay use is high.
A cover-and-wall tamper switch transmits a tamper signal when
the cover is removed from its base, or when the unit is pulled
away from the wall.
An LED provides status for RFSS and Discovery Modes.
