6.4 Alarm Outputs
The AutoDome incorporates two (2) types of alarm outputs: a dry contact relay and three (3)
open collector outputs or transistor outputs.
6.4.1 Configuring a Dry Contact Relay
The dry contact relay acts like an on/off switch. It has a maximum voltage rating of 2 A @
30 DC.
1. Connect the appropriate stripped wire to the AutoDome COM connector.
2. Connect the appropriate stripped wire to the N.O. or N.C. connector, depending on your
requirement.
6.4.2 Configuring an Open Collector Output
Outputs 1, 2, and 3 are open collector types. These outputs must be connected to a positive
voltage between 5 and 32 V to complete the circuit, with a maximum voltage rating of 32 VDC
@ 150 ma.
1. Connect the appropriate stripped wire to the open connector (1, 2, or 3) of the
transistor.
2. Connect the appropriate stripped wire to the ground (GND) connector.
