Setup Considerations > Alarm Input

In addition to the PIR trigger, the unit has an additional alarm input that can be used to trigger a secondary message. This is ideal for a door contact, push button, break beam, a secondary PIR in fact any closing contact even the output from a DVR or NVR such as the Zip range.

For example a shopkeeper might use a push button to “activate” the playing of message 2 when a group of school children enter updating the message to

“Only 2 school children in the store at any one time, CCTV is in operation”

Whichever alarm trigger type you decide to use it will only need to go to to GROUND (GND) momentarily to trigger and play the message. If you wish to continuously loop the playback of the message then a continuous low input trigger would do this.

Alarm Input and PIR Triggering

The Alarm Input (TG-GND / Trigger and Ground) will always override the PIR message, even if the message is playing.

If the Alarm input trigger is released before the message has finished playing, the message will still play out in its entirety.

If the Alarm input trigger is then triggered again, before the message has finished, the message will start from the beginning.
