Zone Inputs
The Reader Expander has 8 zone inputs. The Reader Expander also monitors 16 trouble zones used to report
trouble conditions such as module communication problems.
4.1
Zone Inputs
The Reader Expander can monitor the state of up to 8 zone inputs EOL monitored or dry contact devices such
as magnetic switches, PIR motion detectors and temperature thermostats. Devices connected to these zones
can be installed to a maximum distance of 300m (1000ft) from the Reader Expander when using 22 AWG wire.
Each zone input may be individually configured for normally opened and normally closed configurations with or
without EOL resistors for tamper and short condition monitoring.
When using a zone with the EOL resistor configuration, the controller generates an alarm condition when the
state of a zone changes between open and closed and generates a tamper alarm condition when a wire fault
(short circuit) or a cut wire (tampered) in the line occurs.
When using the EOL resistor configuration, the EOL resistor option must be enabled in the zone programming
so that the tamper and short states can be monitored (for details, refer to the Zones Section in the Protege
Reference Manual).

EOL Resistor Zone Configuration
Each zone input can use a different input configuration. When using the No Resistor configuration, the system
controller only monitors the opened and closed state of the connected input device generating the (OPEN)
Alarm and (CLOSED) Sealed conditions.
