continued
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.
