4-20mA Analog Input Module
Before InstAllIng
This information is included as a quick reference installation guide. Refer to
the control panel installation manual for detailed system information. If the
modules will be installed in an existing operational system, inform the opera-
tor and local authority that the system will be temporarily out of service. Dis-
connect power to the control panel before installing the modules.

generAl DescrIptIon
The M500M-4-20 4-20mA Analog Input Module is intended for use in intel-
ligent, two-wire systems, where the individual address of each module is
selected using the built-in rotary switches. This module allows intelligent pan-
els to interface and monitor two-wire or three-wire sensors, that produce a
4-20mA signal output. It transmits the status (normal, open, or alarm) of one
sensor back to the control panel. The M500M-4-20 has a panel controlled LED
indicator. Only one sensor can be connected to the M500M-4-20.
coMpAtIBIlIty requIreMents
To ensure proper operation, this module shall be connected to a listed compat-
ible system control panel only.
MountIng
The M500M-4-20 mounts directly to 4-inch square electrical boxes (see Figure
1). The box must have a minimum depth of 2
1
/
8
inches. Surface mounted
electrical boxes (SMB500) are available from System Sensor.
