SPEAKER SUPERVISION (679S Siren/Driver)
To supervise a speaker connected to the 679S Siren Driver, connect a
5.6K Ohm resistor between terminal 5 of the 679S and terminal 6 (+) of
zone 4 programmed as a fire zone (program question #14, locations 1 and
2). Replace the 2.2K Ohm EOL resistor on zone 4 with a 5.6K Ohm
resistor. Supervise the speaker for an open circuit (not a short circuit)
across the speaker terminals (4 and 5) of the 679S. Also supervise the
connection between the bell output terminals and the 679S Siren Driver.
If a supervisory occurs, the keypad will indicate that a fire trouble
condition has occurred on zone 4, and fire trouble is reported to the CS, if
enabled (program question #20, location 3). If the siren is already
sounding, the supervision will not take effect until after bell cutoff time.

TRANSFORMER:
Connect the 12VAC 20VA 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 as this may result in improper
operation or damage to the unit.
The AC/LOW BAT LED on the keypad will remain ON while AC power is
present. If an AC loss occurs, the AC/LOW BAT LED will turn off
immediately. If AC remains OFF for 15 minutes, the system will pulse
the keypad buzzer and transmit to the central station, if programmed.
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.
BACKUP BATTERY:
The RED (+) and BLACK (-) flying leads must be connected to a 12VDC,
4-6AH gel cell to serve as backup power in the event of AC loss.
A battery test occurs approximately every 4.5 minutes. Low battery
condition occurs at nominal 11VDC. The keypad AC/LOW BAT LED and
buzzer will pulse slowly when a low-battery condition is detected. The
system reports this condition to the CS, if programmed. Battery
restoration will occur within 4.5 minutes at the next battery test. The
buzzer may be silenced by entry of any valid User Code.
