This circuit cannot be T-tapped or branched in any fashion.
1. Connect the normally open contacts of the alarm initiating devices to
a single two-wire circuit.
2. Terminate across the last device by a listed 47K, 1/2 watt ELR
(part number R-47K, supplied with module).
3. Connect the circuit to M500MJ terminals 6 (-) and 7 (+).
This circuit cannot be T-tapped or branched in any fashion. No external
ELR is required for Style D wiring.
1. Connect the normally open contacts of the alarm initiating devices to
a single four-wire circuit.
2. Connect the four-wire circuit to M500MJ terminals 6 (-) and 9 (-),
then 7 (+) and 8 (+).
The M500MJ includes a magnetic test switch located near the center front
of the module. Activation of this switch causes an open circuit indication
for the indicating appliance circuit.
The M501MJ Monitor Module is an addressable module that is
functionally and electrically identical to an M500MJ Monitor Module, but
offers a smaller package for mounting directly into the electrical box of the
contact-type device being monitored. This module can only monitor a
Style B initiating device circuit and does not have an integral test switch or
LED indicator.
Set the module address
with these switches.
