4-20 mA Configuration

Output 4-20 mA, J9

The 4-20 mA output option will provide a real time analog readout of the gas concentration read by the 301EM
for each of its sensors. It can be connected to a third-party controller, DDC, BMS, etc.
Polarity must be observed.
Do not apply electrical power to the 301EM until
all connections are made. Significant damage
can result from incorrect wiring.
Contact Input, J16
The contact input is mainly used to connect a manual break glass switch to comply with the mechanical code.
It is also possible to connect a third break glass switch in series if needed.
The drawing illustrates the ASHRAE 15 configuration where:
Contact 1 = Electrical shut down (ASHRAE 15 config.)
Contact 2 = Fan activation (ASHRAE 15 config.)
