Terminal Connections

TERMINALS
1 & 2
3(+) & 4(-)
NFPA 72 REQUIREMENT: All the
interconnecting pathways (cable, wire,
etc.) between the alarm system initiating
device (control panel) and the signaling
device (bell, speaker, siren, etc.) shall
be monitored for an occurrence of an
open circuit, which prevents the normal
operation of the system. An occurrence
of an open circuit shall be indicated by a
distinctive trouble signal
2-2
DESCRIPTION
TRANSFORMER:
Connect the 16.5VAC 40VA transformer, utilizing 18awg or larger wire
at a distance not to exceed 15 feet from the panel, to an unswitched
120VAC outlet.
The system can supply up to 1.8 amps of total current.
Do not use any other transformer, as this may result in improper
operation or damage to the unit.
The "AC/LOW BAT" keypad LED remains ON while AC power is
present. If an AC loss occurs, the "AC/LOW BAT" LED turns off
immediately. If AC power remains OFF for 15 minutes, the system
pulses 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 lights immediately, and a Restore code is reported,
if programmed.
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.
BELL SUPERVISION (Bell )
any zone as a fire zone. The bell is then supervised for an open circuit
(not a short circuit) across the bell output terminals; a bell supervision
fault will be displayed at the keypad and reported to the central station
if a report code is enabled. If the bell is already ringing, the supervision
will not take effect until after bell cutoff time.
SIREN SUPERVISION (Self-Contained Siren/Speaker)
(Not for use in UL installations.) To meet the NFPA 72 requirement
program any zone as a Fire Zone. The siren is then supervised for an
open circuit (not a short circuit) across the bell output terminals; the
keypad will indicate that a supervision condition has occurred and bell
supervision is reported to the CS if enabled (program mode 2, Question
79, locations 1,2). If the siren is already sounding, the supervision will
not take effect until after bell cutoff time.
