The M500M-4-20 Analog Input Module allows the connection

of 4-20 mA output sensors to a fire alarm control panel (FACP). The

module converts the sensor output to a common communication

protocol that can be interpreted by the FACP for monitoring and

display. There are numerous sensors available in the marketplace

that communicate using a 4-20 mA output, including gas sensors,

temperature sensors, air speed sensors, and more.

The M500M-4-20 Module includes numerous safeguards and

protective features to ensure trouble-free operation. The module

accepts both 3-wire (device sink) and 2-wire configurations. The

external power supply is isolated from the communication line. In

addition, a 500 mA current limiter and a cutoff circuit protect the

module’s electrical supply from short circuits. In the event of a

short, the output voltage will cycle within safe limits until the short

is removed. The output signal is sampled and filtered for transients

and noise prior to passing the signal on to the FACP. If the current

running through the sensing circuitry exceeds 25 mA, the output

voltage will shut down and the short protection process will begin.

As with all of the System Sensor intelligent modules, the

M500M-4-20 Analog Input Module is rigorously designed and

tested for electromagnetic compatibility and environmental

reliability, in most cases exceeding industry standards. The device is

equipped with a panel-controlled red LED for local status indication.

The standard SEMS terminals will accept wiring from 18ga to 12ga

(AWG).
