Model ALARM INTERFACE

Installation & Operations Manual

Product description

The ALARM INTERFACE allows an emergency system to trigger a pre-recorded
emergency DMX512 backup look. In normal operation, the ALARM INTERFACE
passes DMX512 signals untouched. While triggered, the incoming DMX signal is
disconnected and the ALARM INTERFACE sends the emergency backup look. The
emergency backup look can be set to any lighting levels required by the installer.

Environmental

Operating temperature: 0-40º C
Operating humidity: 10-90% non-condensing
Indoor use only

Electrical ratings

Input: 90 - 132 VAC, 50 - 60Hz, 0.25A

Mounting

The ALARM INTERFACE enclosure can be mounted on any flat surface meeting the
environmental requirements above. Conduit knockouts are provided for ease of
installation of wiring.

Power wiring

The ALARM INTERFACE is powered by 120VAC, 0.25A. Line and neutral connections
are made via terminal blocks. Care must be taken to avoid routing power wiring over
the circuit board or in the vicinity of low voltage wiring.

DMX512 wiring

The incoming DMX512 signal (from the control console) must be connected to the
DMX_IN terminal block. Connections are provided for common (C), data minus (-), and
data plus (+). DMX512 cabling to the dimmers and/or fixtures must be connected to the
DMX OUT terminals. Similar connections are provided.

Alarm closure wiring

The CLOSURE FROM ALARM terminals must be connected to the system which will
trigger the emergency condition. The closure must be a maintained form C type
capable of carrying 80mA at 5VDC. While the contacts are shorted, the emergency
look will be activated. While the contact closure inputs are not shorted, the incoming
DMX512 signal will be passed to the output unchanged.

Recording the emergency backup look

The emergency backup look comes from the factory defaulted to all 512 channels set to
full. If some other emergency backup look is required, perform the following procedure
to record the new lighting levels.

- Connect a DMX512 source to the DMX INPUT.

- Set the emergency backup lighting levels using the control source just connected.

- Press the “RECORD PRESET” switch.

- The red REC/PWR LED will flash indicating that the recording process has begun.

- After about 1 second, the green REC DMX LED will turn on indicating that the ALARM
INTERFACE is receiving a good DMX512 signal. The red REC/PWR LED will
continue to flash.

- After another second, the green REC DMX LED will turn off and the red REC/PWR
LED will turn on solid. This indicates that the emergency backup look has been
recorded and that the ALARM INTERFACE has returned to normal operation.

Note 1: If the green REC DMX LED does not turn on during this process, this indicates
that no valid DMX signal is being received. The recording process is aborted without
changing the existing emergency backup look.

Note 2: The emergency backup look is held in non-volatile flash memory. No power or
battery is required to retain the contents of the emergency backup look.

Verifying the emergency backup look

A test jumper has been provided to allow the installer to verify that the proper
emergency backup look has been recorded. To verify the contents of the emergency
backup look, perform the following procedure.

- Turn off the normal source of DMX512 signals. Verify that the room lighting is off.

- Move the test jumper from the NORM position to the TEST position. The jumper is
located just above and between the DMX OUT and CLOSURE FROM ALARM
terminal blocks.

- Verify that the room lighting goes immediately to the emergency backup look levels.

- Move the test jumper back to the NORM position.

- Verify that the normal source of DMX512 can now control the room lighting.

If the emergency backup look is not as desired, record a new look as described earlier.
