2-wire detectors being monitored must be UL or ULC compatible

with the module. The M502M module is addressed through the

communication line of an intelligent system. It transmits the status

of one zone of 2-wire detectors to the fire alarm control panel. Status

conditions are reported as normal, open, or alarm. The interface

module supervises the zone of detectors and the connection of the

external power supply.

M500S Control Module

The M500S Control Module provides supervised monitoring of

wiring to load devices that require an external power supply to

operate, such as horns, strobes, or bells. It is capable of Styles Y and

Z supervision. Upon command from the control panel, the M500S

module will disconnect the supervision and connect the external

power supply across the load device. The disconnection of the

supervision provides a verification to the panel that the control relay

actually turned on. The external power supply is always relay isolated

from the communication loop, so that a trouble condition on the

power supply will never interfere with the rest of the system. Full

analog measurement of the supervised wiring is transmitted back to

the panel and can be used to detect impedance changes or other

special test functions.

M500R Relay Module

The M500R Relay Module contains two isolated sets of Form C

contacts, which operate as a DPDT switch. The module allows the

control panel to switch these contacts on command. No supervision

is provided for the notification appliance circuit.

M500DR Dual Audio Riser Module

The M500DR module is a special applications control module that is

designed to supervise a loop of speakers under normal conditions.

When commanded by the control panel, the module then connects

either of two audio amplifier circuits to the speakers. In this way,

two separate audio messages can be broadcast over a single set of

speakers with a single module.

M500FP Firefighter Phone Module

The M500FP module is intended to monitor and control a loop of

firefighter phones. It has the ability to differentiate between normal,

off-hook, and trouble conditions. When taken off-hook, a phone will

immediately receive a ringing tone, and the panel will receive an off-

hook indication. The panel can then connect that off-hook phone to

the main riser for the system.
