Attaching an External Device to an EDVR
The EDVR provides facilities to report 3 auxiliary alarm outputs for associated equipment – such as the spotlight,
buzzer, or blinker alarm – and 16 alarm inputs for the 16CH EDVR version (9 for the 9CH; 4 for the 4CH).
The alarm outputs are related to the alarm indication.
The input alarms are reported to the management system and are activated by a closed or open loop condition.
Connect an alarm out, alarm input, and a peripheral device as shown in the following diagram.

Alarm Input: An input connection to the EDVR that triggers the EDVR unit to active (buzzer and
message display) if one of the alarm input links (the sensor of each channel) is activated (that is, turned
ON).

Alarm Output: An output connection to the warning devices that triggers the warning unit to turn on an
alarm with sound or light. When combining a warning device to the EDVR, connect the Pin#1 GROUND
and the Pin#3/15/16 ALARM OUTPUT.
