Honeywell HD-DVR-1008, HD-DVR-1004, HD-DVR-1016 Alarm Input and Output Connection, Audio Output

Installation and Connections

Audio Output

The audio output signal parameter is usually over 200mv 1KΩ (BNC). It can directly connect to low impedance earphones, active sound box or amplifier-drive audio output device.

If the sound box and the pick-up cannot be separated spatially, it is easy to cause a squeaking noise. In this case you can adopt the following measures:

•Use better sound pick-up with better directing property.

•Reduce the volume of the sound box.

•Use more sound-absorbing materials in decoration to reduce voice echo and improve acoustics environment.

•Adjust the layout to reduce the occurrence of the squeaking.

Alarm Input and Output Connection

Please refer to the following sheet for alarm input and output connection.

There are two alarm input types for you to select: normal open (NO) and normal close (NC).

1. Alarm input

aPlease make sure alarm input mode is grounding alarm input.

bGrounding signal is needed for alarm input.

cWhen you are connecting two DVRs or connecting one DVR and one other device, please use a relay to separate them

2.Alarm output

The alarm output port should not be connected to a high power load directly (It shall be less than 1A) to avoid high current which may result in relay damage. Please use the co contactor to realize the connection between the alarm output port and the load.

3.Please make sure the front-end devices have been well earthed. Improper grounding may result in chip damage.
