TERMINALS 1 & 2

The system is powered with a 16.5V 20VA "non-fused" UL listed
class II transformer. The AC transformer is connected to terminal
1 and 2. It is recommended that the AC transformer be connected
with a minimum of 18 gauge wire at a distance of no more than 50
feet. The AC fail system monitor has a built in 15 second fault delay
that minimizes nuisance alarms caused by momentary power
outages.

To maintain proper operation, the SC system must have a 12 volt
rechargeable gel type battery installed. The system was designed
to support a 4 to 18 amp hour (AH) battery. The system provides a
float charge of 13.75VDC and provides continuous charging current
when operating at the suggested rated power output.

Once AC power is lost to the system, the battery automatically takes
over. The SC system continuously monitors the battery condition
with or without the AC power removed. If the battery voltage falls to
an 11.0VDC level, the low battery detector will activate and a low
battery trouble condition will be annunciated at the keypad. The
trouble condition will exist until the battery voltage reaches an
acceptable level.
To silence the trouble enter the fault mode key sequence at the

keypad. [PPPP]

auxiliary power fuse F2. Negative termination for auxiliary devices
are wired to terminals 5 or 6.

nation for smoke detectors are wired to terminal 11. To enable this
feature a “7” must be programmed in item 30 - Second Miscella-
neous Function select. Once programmed, pressing the [1] and [3]
keys simultaneously will reset the smoke output for approximately 5
seconds.

ARNING OUTPUT

(TERMINAL 14)

Output is available for connecting a remote prealarm device (piezo
or equivalent). The device must operate at 12.5VDC and requires
no more than 50mA of current. Connect the positive (+) wire of the
device to terminal 3 or 4, return the negative (-) wire to terminal 14.
The device will produce a steady tone when in entrance delay and
a pulsating tone when in exit delay, test or trouble modes. When the
Chime feature is enabled this output will operate along with the
keypad sounder for chime, creating a short tone any time a chime
zone is violated or restored.
