Systemsensor M500M Intelligent module Datasheet

500 Series
Intelligent Modules
The System Sensor intelligent module products are
designed to meet a wide range of applications.
Features
• SEMS screws for easing wiring
• Panel controlled status LED (except M501M)
• Analog communications
• Rotary address switches (except M500X)
• Low standby current
Monitor and control modules can be used to supervise and activate
sounders, strobes, door closers, pull stations, waterflow switches,
conventional smoke detectors, and more. Each module is rigorously
designed and tested for electromagnetic compatibility and
environmental reliability, in many cases exceeding industry standards.
Modules are addressed with easy-to-use rotary code switches. Full
size modules mount in standard 4 in × 4 in × 21⁄8 in junction box.
Wiring terminals are easily accessible for troubleshooting.
• Mounts in standard 4˝ junction box
M500M Monitor Module, M501M Mini Monitor Module, and
M500DM Dual Input Monitor Module
System Sensor monitor modules provide an interface to contact
devices, such as security contacts, waterflow switches, or pull
stations. They are capable of Styles A and B supervised wiring to
the load device (M500M device is capable of Style D). Conventional
4-wire smoke detectors can be monitored through their alarm
and trouble contacts, wired as an initiating loop to the module.
In addition to transmitting the supervised state of the monitored
device (normal, open, or short), the full analog supervision
measurement is sent back to the panel. This allows detection of
impedance changes in the supervised loop to the monitored device.
The M500DM module is capable of monitoring two separate Class B
circuits simultaneously, making it ideal for waterflow tamper switch
and flow switch monitoring. The compact size of the M501M module
allows it to fit inside devices or junction boxes behind devices.

M500X Isolator Module
The M500X Isolator Module is an automatic switch that opens
when the line voltage drops below four volts. Isolator modules
should be spaced between groups of sensors or modules in a loop
to protect the rest of the loop. If a short occurs between any two
isolators, then both isolators immediately switch to an open circuit
state and isolate the devices between them. The remaining units
on the loop continue to fully operate. A maximum of 25 devices are
recommended for each group.
M502M Zone Interface Module
The M502M Zone Interface Module allows intelligent panels to
interface and monitor 2-wire conventional smoke detectors. All
continued
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 offhook indication. The panel can then connect that off-hook phone to
the main riser for the system.
