3.3.2 Relay Output
The following wiring connection diagrams shows wiring the detector when a relay output is
required. Reversal of polarity across terminals 1 & 2 enables Micropack RS485 communication
on terminals 3 & 4. This communication protocol when used with Micropack applications allows
configuration changes to the detector.

NOTE: EOL and Alarm resistors values are defined by the client and the
control system/fire panel which the detectors are being integrated into.
