DESCRIPTION
1 & 2
TRANSFORMER:
Connect the 16.5VAC 25VA transformer, utilizing 18awg wire at a
distance not to exceed 15 feet from the panel, to an unswitched 120VAC
outlet.
Do not use any other transformer, since this may result in improper
operation or damage to the unit.
The “AC/LOW BAT” keypad LED will remain ON while AC power is
present. If an AC loss occurs, the “AC/LOW BAT” LED will turn off
immediately. If AC power remains OFF for 15 minutes, the system will
pulse the keypad buzzer and transmit a power-loss message to the
central station, if programmed to do so. THE KEYPAD BUZZER CAN BE
SILENCED by entry of any valid user code. When AC restores, the
“AC/LOW BAT” LED will light immediately, and a Restore code will be
reported, if programmed.
3
EARTH GROUND:
Connect this grounding lug to a cold water pipe utilizing #18awg wire at
a distance of no greater than 15 ft. Use a noncorrosive metal strap firmly
secured to the pipe to which the lead is electrically connected and
secured. If the premises pipes terminate in PVC, this terminal must be
connected to a 6-foot grounding rod.
4(+) & 5(-)
BELL OUTPUT:
The total output power available for sounding devices is 1 amp at 11.5 -
13.1VDC. These terminals will deliver CONSTANT output on
BURGLARY, AUDIBLE PANIC and BELL TEST. On a FIRE condition, a
PULSED or TEMPORAL output can be generated. There are separate
bell cutoff times programmable for Burglary and Fire conditions within
the programming sequence. For UL Household Fire Warning System
installations, the speaker must be mounted indoors for best audibility.
Also, for UL installations, use only one speaker.
NOTE: Before connecting sounding devices, please consult their
specifications for proper current draw. Otherwise, the bell fuse (F1) may
be blown.

SIREN SUPERVISION INPUT:
The Bell Output may be supervised when a conventional bell or a
self-contained siren is connected. When connecting a conventional bell or
a self-contained siren to the bell output terminals (4 & 5), the jumper JP3
must be placed across pins 1 and 2. When connecting an external siren
driver to the bell output terminals, the supervision wire is connected to
the siren supervision terminal of the siren driver, and the jumper JP3
must be placed across pins 3 and 4. A supervisory condition will generate
a pulsing keypad sounder. Also, the supervisory LED on the keypad will
pulse. The sounder may be silenced by entering a valid user code while
the system is disarmed. The LED will continue to pulse until the
supervision is fixed. If a bell, self-contained siren, or external siren driver
is not connected to the bell output terminals, a 100-ohm resistor must be
placed across the siren supervision input to prevent a bell supervision
error. Bell supervision will be reported to the CS if enabled.
