980 System Module Accessories.
In systems without a control panel, it is usually desirable
to add “outboard” switches for remote operation of
certain 980 system management tools.
Remote Power Switch.
If your system does not include a Control Panel, you may
want to turn the system on and off using a remote key
switch or toggle switch.
• Use any SPST (single-pole, single-throw) switch you
prefer. Low current switches will work perfectly well.
• Connect the switch between the “POWER” and
“COM” pins of the 980’s ”REMOTES” terminal block.
TheftAlert
™
TheftAlert
is an optional feature of the Access
™
System that provides a merchandise sentinel or security
system for the products on display.
TheftAlert
can sound an alarm in the event that products are removed
from the display without prior authorization. This feature is available upon request at the time of purchase,
or you can install it later. Contact your Audio Authority Account Manager for details.
Once
TheftAlert
is armed, a special monitoring circuit continually looks to see that all electronic products
connected to the system maintain continuity to ground. If products are disconnected without prior entry of
an authorization code, then
TheftAlert
senses the loss of continuity in the system and sounds an external
alarm (not included). No additional circuitry or buffers are ever in the audio signal path with
TheftAlert
.
TheftAlert
™
can send output to many types of warning devices, such as sirens, buzzers, lamps, and so on.
• Connect a 12 volt DC siren or other device, drawing less than 1 amp, to the (+) and (–) “12V Siren” termi-
nal block on the Model 980 (see Figure 38).
If you wish to connect
TheftAlert
to an existing alarm or security system’s control box, use the relay con-
tacts of the “TheftAlert” terminal block on the 980’s circuit board. There are 3 pins to consider in this type
connection:
COM
= Common Ground
NO
= Normally Open Contacts
NC
= Normally Closed Contacts
• Do not exceed a 1 Amp, 120 volt AC load on these relay contacts.
TheftAlert
can be turned on and off with a 902 or 903 Control Panel. However, if you do not have a Control
Panel, you must have a method of “resetting” the
TheftAlert
circuit when the alarm or siren goes off.
TheftA-
lert
can be reset with a remote switch regardless of whether or not your system has a control panel. Many
users who have a control panel prefer a separate reset switch as an addition to the control panel’s reset
function.
• Connect a SPST (single pole, single throw) switch between the “TA” (reset) and “COM” pins on the
“Remotes” terminal block located on the 980’s circuit board.
• To ACTIVATE the
TheftAlert
circuit, with or without a control panel, cut or remove the wire jumper on the
980 circuit board labeled “Cut To Activate.”
• If you have a control panel, consult your 902/903 User’s Guide for more information on
TheftAlert
secure
commands.
