3.9 Optional
Modules
3.9.1
Class A Option Module (CAOM)
The Class A Option Module (CAOM) provides Class A signaling for the
notification appliance circuits and Class A, Style 6 or 7 signaling for the signaling
line circuits. Style 7 wiring requires the use of an M500X Isolator Module on both
sides of a device. It also provides a disconnect switch for each signaling line
circuit and a common disconnect switch for both notification appliance circuits.
See Table 3-4 for wiring connections.
3.9.2
Municipal Circuit Option Module (MCOM)
The Municipal Circuit Option Module (MCOM) provides output for a local energy
city master box, releasing solenoid programmed via the FCP or CAMWORKS, or
reversed polarity output for leased line connection intended for connection to a
polarity reversal circuit of a remote station receiving unit having compatible
ratings. See Table 3-4 for wiring connections. Refer to the Compatibility
Addendum P/N 9000-0427 for a list of compatible solenoids.

Printer Transient Module (PTRM)
The Printer Transient Module (PTRM) provides sufficient transient protection to
the RS-232 output to comply with the applicable codes for wiring leaving the
confines of the control box, as well as the proper isolation of the signal to prevent
damage or interference caused by a connection to certain EDP devices.
