Inputs
The reader expander can monitor the state of up to 8 inputs. These inputs can be connected to a variety of EOL
monitored or dry contact devices such as magnetic switches and PIR motion detectors. Devices connected to the
inputs can be installed to a maximum distance of 300m (1000ft) from the module when using 22 AWG wire. Each
input may be individually configured for normally opened and normally closed configurations with or without EOL
resistors for tamper and short condition monitoring.

⦁
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 reader expander has been evaluated for UL 294 and CAN/ULC-S319 standalone access
control.
When using an input with the EOL resistor configuration, the controller generates an alarm condition when the
state of an input 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 input programming so
that the tamper and short states can be monitored. For more information, refer to your Protege programming
reference manual.
EOL Resistor Input Configuration:
Each input can use a different input configuration. To program a large number of inputs with the same
configuration use the multiple selection feature within the Protege software.
When using the 'No Resistor' configuration the controller only monitors the opened and closed state of the
connected input device, generating the alarm (open) and restore (closed/sealed) conditions.
