PRT-RDE2-PCB
Protege Ethernet 2 Reader Expander
Installation Manual | June 2017

Zone Inputs
The Protege Reader Expander has 8 Zone Inputs. The reader expander also monitors 16 trouble zones used to
report trouble conditions. A trouble zone is in most cases not physically connected with a device, rather it is
related within the system. For example, a module communication fault causes a trouble zone to open as a result
of the communication failure.
5.1
Zone Inputs - Reader
The Protege Reader Expander can monitor the state of up to 8 zone inputs such as magnetic contacts, motion
detectors and temperature sensors. Devices connected to these zones can be installed to a maximum distance
of 300m (1000ft) from the Controller when using 22 AWG. The Controller supports normally opened and
normally closed configurations with or without EOL resistors on a per zone configuration setting.
UL
ULC
Magnetic contacts shall be listed to UL 634 to comply with UL installation standards and
ULC/ORD-C634 to comply with ULC installation standards.
Motion detectors and temperature sensors shall be listed to UL 639 to comply with UL installation
standards and ULC-S306 to comply with ULC installation standards.
The PRT-RDI2-PCB has been evaluated for UL 294 and CAN/ULC-S319 standalone access
control.
Zones can be programmed from the Protege LCD Keypad (PRT-KLCD) or using the Protege System
Management Suite (PRT-SMGT). RD001:01 to RD001:08 represent Zone 1 to Zone 8 on the Protege Reader
Expander (Substitute the module address for the appropriate address being programmed).
When using a zone with the EOL resistor configuration, the controller generates an alarm condition when the
state of a zone changes 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 turned on for the zone(s) so that the
tamper and short states can be monitored (refer to Zones Section in the Protege Reference Manual).
