DLM-4/DLM-4L

Video Transmission Module

The DLM-4 is the video capture, compressor and transmission module and must be used on all

Downlook applications, the DLM-4 connects to one of the listed Alarm Panels, Communicator or

with the DLM-4L onto the Power 832 - 5108L Module.

One single BNC post provides for a direct single video connection with 75 ohm termination.

The DLM-4 can capture and store 4 video pictures and transmit those images when instructed

to do so by the Alarm panel or communicator. Time of first image capture is programmable in

the control panel and the time spacing between additional captures is fully programmable on

the DLM-4 by way of dip switches.

A programmable time for first image capture allows for the flexibility of Downlook activation from

Infrared detectors, Door contacts, Hold up buttons and glass break detectors.

A rotary feature provides for alternate image capture for up to four cameras.

All DLM-4L function and features are programmed into and provided by the Power832 control

panel.

E.g. If used with two cameras, on a common alarm condition the first image will be taken by

camera one, second by camera two, third by camera one, fourth by camera two.

Dip switch selection provides for a switched output on camera supervision, after the cameras

are connected and power applied disconnection of a camera or loss of video signal will result in

the output changing state.

No Video adjustment or calibration is required. Power requirements are 10.5 - 16 VDC; 300ma

@12V.
