5 Alarms and Relay Connections
5.1 Alarm Inputs
The AutoDome provides seven alarm inputs. Each input can be activated by dry contact
devices such as pressure pads, passive infra-red detectors, door contacts, and similar devices.
The table below summarizes the size and distance wires.
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 addi-
tion 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.
5.2 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 resis-
tor 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.).
5.2.1 Configuring a Normally Open Supervised Alarm
1. Install a 2.2 K end-of-line resistor in the alarm circuit.
2. Connect the alarm to input 1 or 2 (pin 5 or 6) and to the ground (pin 7) at the AutoDome.

3. From the AutoDome main menu, select Alarms Setup>Inputs Setup, and set the Alarm
Input # to N.O.S. See the table below for contact and condition details.

NOTICE! Only Alarms 1 & 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.
