current draw. Otherwise, the bell fuse (F3) may be blown. An option
exists to supervise the bell output terminals if zone 4 is programmed as a
fire zone (see program questions #10-13); refer to the following notes:
P1: VBELL (+) T1 (-) TRIGGER #1 OUTPUT:
P1-VBELL (+) & P1-T1 (-) or terminals 12 & 13 can be used for a trigger
#1 output. See programming question #07, location 3 for valid trigger
types. NOTE: In order to connect devices to the triggers use connector
XL-2GTC (trigger cable). Unless otherwise specified, the trigger output is
normally floating and actively sinks on activation (switched negative).
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.
BELL SUPERVISION (Mechanical Bell)
- To meet the NFPA 72 requirement
program zone 4 as a Fire Zone (program question #13, locations 1
& 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 #18, location 3). If the bell is already ringing,
the supervision will not take effect until after bell cutoff time. See the
diagram on the next page:

SIREN SUPERVISION (Self Contained Siren/Speaker)
- To meet the NFPA 72
requirement program zone 4 as a Fire Zone (program question #13,
location 1). The siren 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 #18, 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. See the
diagram below:

SPEAKER SUPERVISION (VS-299 Siren/Driver)
- To supervise a speaker
connected to the VS-299 Siren Driver connect terminal 1 of the
VS-299 to the positive terminal of any zone programmed as a 24
Hour Trouble zone (program questions #10 - 13, locations 1 & 2).
The speaker is then supervised for an open circuit across the speaker
terminals (4 & 5) of the VS-299 and a code is reported to the CS if
enabled (program question #10 - 15, locations 3 & 4). Also, the connection
between the bell output terminals and the VS-299 Siren Driver may be
supervised by programming zone 4 as a Fire Zone (program
