Note
Any unused hardwire zones should always have a 2K resistor wired
across the zone terminals to terminate them.
Possible wiring types are:
l Supervised EOLR (normal open or normal closed)
l Double balanced
l Triple balanced.
All types are described in detail further below.
3.8.2.1 Supervised EOLR
For a normally open circuit, you wire
the sensor (N.O.) in parallel to the
EOL resistor R1.
For a normally closed circuit, you wire
the sensor (N.C.) in series with the
EOL resistor R1.

Acceptable EOL values for R1 are defined in the table below. The electrical
bands for each R1 value are indicated below:
Alarm < Ready < Alarm / Fire & CO trouble
R1 = 1K
