4.3.7
Unmonitored General Purpose Input (GPI)
The Unmonitored GPI is a programmable input which can be configured to initiate a number of different
actions, including, by default, a Remote Reset function. Refer to Section 5.5.11 on page 66 for further
information.
A voltage input of between 5V and 30V signals GPI ON. Less than 2V signals GPI OFF. The input is isolated
from the system by an opto-coupler device.
4.3.8
Monitored General Purpose Input (GPI) Wiring
The monitored GPI senses contact closure and is configurable to initiate the same actions as the unmonitored
GPI. "Remote Reset" is the default setting. A closed contact signals GPI ON and open contact signals GPI
OFF.
A 10K end of line resistor is used to allow the detector to monitor for open circuit faults in the wiring from the
detector to the contact. Refer to Section 4.3.11 for information on correct wiring of the End of Line resistor.
