1. Program the zone/point as “Supervisory” type with
keypad-only announciation when in alarm. Do NOT
use a zone/point that is normally used for 2-wire
smoke detectors.
2. The power supervision relay (RM-2) is only used
when the LE4020 is not powered by the control
panel. The relay is not required since a loss of input
power to the control panel will generate a signal to
the CMC.
3. Output 4 on the LE4020 must be set as “Active
High” (default).
4. This equipment has no mains on/off switch. The plug
of the direct plug-in power supply is intended to
serve as the disconnecting method if the equipment
must be quickly disconnected. Ensure that access to
the mains plug and associated mains socket/outlet is
never obstructed.
The following wiring diagrams are examples of ULC Listed Fire Monitoring Installation connections.
