If the Optional plug-in communication board is fitted, connect terminal 15 and 14 of the indicator to (+) and (-) terminals of the
Master device.
For reliable noise free communication, use a pair of twisted wires inside screened cable as shown in Figure
11.6. The wire should have less than 100 ohms/km nominal DC resistance (Typically 24 AWG or thicker). Connect the
terminating resistor (Typically 100 to 150 ohm) at one end to improve noise immunity.
REMOTE ALARM ACKNOWLEDGMENT INPUTS
(Terminals : 14,15)
(Applicable if the Option plug-in module for Remote Alarm Acknowledge is fitted).
