4 Alarms and Relay Connections
4.1 Alarm Inputs
The AutoDome provides seven alarm inputs. Each input can be
activated by dry contact devices such as pressure pads, passive
infrared detectors, door contacts, and similar devices. The
table below summarizes the size and distance wires.
Table 4.1 Alarm wire guide
You wire alarms either Normally Open (N.O.) or Normally
Closed (N.C.), and must program the alarm inputs N.O. (the
default) or N.C. through the AutoDome main menu.
The AutoDome incorporates two (2) types of alarms: Non-
supervised and Supervised. In addition to transmitting an alarm
condition, a supervised alarm also transmits a tamper
condition. Depending on how the alarm is configured, a short or
a break in the alarm’s circuit can trigger the tamper signal.
4.2 Configuring Supervised Alarms (inputs 1
and 2)
To configure Alarm 1 or 2 (pin 5 or 6) for supervision, you must
install a 2.2 K end-of-line resistor in the circuit. Then, you
program the alarms through the AutoDome main menu to either
Normally Open Supervised (N.O.S.) or Normally Closed
Supervised (N.C.S.).

NOTICE!
Only Alarms 1 and 2 (pins 5 or 6) can be configured for
supervision. Once a supervised alarm is programmed it does
not need to be enabled to indicate a tamper condition.
