Inputs
The input expander can monitor the state of up to 8 inputs (16 with input duplex mode). 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 should 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 should be listed to UL 639 to comply with UL
UL
installation standards and ULC-S306 to comply with ULC installation standards.
ULC
The Protege input expander has been evaluated for UL 1610, UL 1635, CAN/ULC-S304 and
⦁
CAN/ULC-S559.
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.
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.
To utilize the input duplex mode configuration shown below, simply assign additional inputs to the expander
from within Protege to create a duplexed pair.
