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
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.
