ALARM INTERFACE UNIT
OPERATION
Power Sources
Power is supplied via the appended 3-wire power cord. Power
consumption is approximately eight watts.
The AD2096A is configured for 120VAC, 50/60Hz,
primary power source. Operating power voltages must be
held within the 105V and 125V range.
The AD2096-1 is configured for a 230VAC, 50/60 Hz
primary power source. Operating power voltages must be
held within the 198V and 250V range.
Powering Up
The AD2096A AIU does not contain a power On/Off switch.
A green POWER LED indicator, located on the rear panel,
illuminates when power is applied. If an alarm input is
activated, the green ALARM LED on the rear panel will
illuminate.
The 120 VAC units are supplied with a pendant 3-wire cord
and plug for mating to the primary source outlet. The 230 VAC
units are supplied with a Euro-style IEC 320 type inlet. A
suitable, detachable cord should be connected between the IEC
320 inlet and power source. The cord should conform to all
national and local use code requirements.
Note: DO NOT CONNECT THE EQUIPMENT TO THE
POWER SOURCE UNTIL READY TO POWER UP.
THE SOCKET OUTLET SHALL BE LOCATED
NEAR THE EQUIPMENT, AND SHALL BE
READILY ACCESSIBLE.
Make all connections to the AD2096A Alarm Inputs and
Output Relay connections and set the DIP switches as
indicated on page 2 before applying power to the AD2096A.
Alarm Response Operation
Each alarm input signal is assigned an alarm contact number
(ACN) by the AD2096A. The setting of DIP switch S1 (see
page 2) determines the range of ACN's for each AD2096A.
Depending on the Matrix Switching System capabilities, a
maximum of 1024 alarm contacts (ACN's) can be programmed
for alarm event response by that system.
When an alarm condition exists, the AD2096A AIU detects the
closure (or opening) of the contact, depending on the DIP
switch configuration (S2, page 2). The AD2096A AIU then
issues an alarm message containing the corresponding alarm
contact number (ACN), via the RS-232 COM OUTPUT Port,
to the Matrix Switching System for camera callup to monitors.
When an alarm contact is detected, the AD2096A AIU also
activates an internal relay, providing both an output closure
(NO pin) and an opening (NC pin); this relay output can be
used to turn on/off lights, VCRs, etc. The alarm relay output
continues to be active until the alarm condition is removed.
Once the alarm condition is deactivated (contact is cleared),
the alarm relay is held for 10 seconds, then is deactivated.
Programming Alarm Contacts
Each alarm contact (ACN) input to an AD Matrix Switching
System is armed for camera callup on a specific monitor.
Individual camera inputs and camera salvos, each with preset
scenes and auxiliary actions, may be programmed for
automatic callup to monitors in response to alarm inputs.
When the switching system is armed for alarm contact (ACN)
inputs, the video input associated with the ACN is
automatically displayed when that alarm input is detected by
the AD2096A AIU and sent to the switching system. Refer to
the Alarm Programming sections in the appropriate Matrix
Switching System Installation Manual for the commands to
arm alarm contacts, monitors, and cameras.
