DESCRIPTION
The NRX-M711 radio input-output module is a battery operated RF
device designed for use with the NRXI-GATE radio gateway, running
on an addressable fire system (using a compatible proprietary
communication protocol).
It is a dual module having separate input and output capability,
combined with a wireless RF transceiver and is supplied with a
wireless back box.
This device conforms to EN54-18 and EN54-25. It complies with the
requirements of 2014/53/EU for conformance with the RED directive.

Input Module
requires 47K EOL for normal operation.
Output Module
requires 47K EOL at the load for normal
operation in supervised mode.
If the load is a low impedance (compared to the EOL) a
series diode should be added for correct load supervision
(see
Figure 2
for diode polarity).
