Supervised (Software Configurable) Alarm Inputs

Note: For termination resistor values, refer to the
The eight (8) inputs that are available on the DDC are software configurable alarm inputs that can be used
for alarm device monitoring. Each of these inputs can be configured, via the Access Control software, as
either N/O (normally open) or N/C (normally closed) in combination with either supervised or unsupervised
wiring. These alarm inputs are connected using Inputs 1 - 8. Inputs 1 and 6 are used for the door contacts,
inputs 2 and 5 are used for request to exit switches, and inputs 3, 4, 7, and 8 are available for auxiliary inputs
points.
Each input that is configured as a supervised alarm must be terminated with two (2) 1K (1000) ohm resistors
(1% tolerance - 1/4 (0.25) watt. N/O and N/C alarms are terminated identically.)
