Eaton’s 4 to 20mA addressable modules interface with gas detection modules to enable alarms to be reported on Eaton’s range of addressable fire alarm system panels. The interfaces have unique addresses on the loop and built-in isolators for loop short circuit protection.
Each of the DIL switches JP1, JP2 and JP3 can be programmable to set the threshold level for pre-alarm 1, pre-alarm 2 and alarm respectively. This can be expressed as a percentage of L.E.L (lower explosion limit) or PPM (parts per million).
