For UL Household Fire Warning System installations, the speaker must be mounted indoors for
U L
best audibility. Also, for UL installations, use only one speaker.
NFPA 72 REQUIREMENT: All the inter-
connecting 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.

BELL OUTPUT:
The total output power available for sounding devices is 1 amp at 10.5 -
15.5VDC for residential applications, or 12.0 - 14.4VDC for commercial
installations (650mA for UL installations). These terminals will deliver
CONSTANT output on BURGLARY, AUDIBLE PANIC, and BELL
TEST. On a FIRE condition, a PULSED output will be generated.
There are separate bell cutoff times programmable for burglary and fire
conditions within the programming sequence.
NOTE: Before connecting sounding devices, refer to their individual
specification sheets to determine current draw. Otherwise, the PTC may
cause continuous circuit interruption. An option exists to supervise the
bell output terminals if any zone is programmed as a fire zone (see Pro-
gram Questions 17–23); refer to the following information.
BELL SUPERVISION (Bell) - To meet the NFPA 72 requirement, pro-
gram any zone as a Fire Zone (Program Question 22, Locations 1 and 2).
The bell is then supervised for an open circuit (not a short circuit) across
the bell output terminals; the keypad will indicate that a fire trouble
condition has occurred and fire trouble is reported to the CS if enabled
(Program Question 32, Location 3). If the bell is already ringing, the su-
pervision will not take effect until after bell cutoff time. Refer to the fol-
lowing diagram:

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 (Program Question 22, Location 1). The siren is then super-
vised for an open circuit (not a short circuit) across the bell output termi-
nals; the keypad will indicate that a fire trouble condition has occurred
and fire trouble is reported to the CS if enabled (Program Question 32,
Location 3). If the siren is already sounding, the supervision will not take
effect until after bell cutoff time.
NOTE: Use FBII models ZR-815C, ZR-815EC, or ZR-830EC. Refer to the
