Installing External Sounders - Honeywell VISTA-128BPT Installation And Setup Manual

Installing External Sounders

The VISTA-128BPT/VISTA-250BPT provides a bell circuit output for operating fire and burglary alarm notification
appliances. The alarm output is rated as follows: 10VDC – 14VDC, 1.7A max., power-limited.
•
For Household Fire and combination Household Fire/Burglary installations, the total current drawn from the
U L
auxiliary power, polling loop, and alarm output combined must not exceed 750mA.
•
For Household Burglary installations, the total current drawn from the alarm output must not exceed 1.7A. A
battery must be installed, as it supplies the current for the combined auxiliary power, polling loop, and alarm
output in excess of 750mA.
The output has the following options:
•
Selectable for supervision.
•
Selectable for confirmation of arming ding.
•
Selectable to chime when entry/exit or perimeter zones are faulted.
•
Selectable for a timeout of 2-30 minutes.
U L
Burglary bell circuits must be programmed for a timeout of 16 minutes or longer.
UL985 Household Fire or Combination Household Fire/Burglary Installations
For installations that must provide UL Listed protection, the total combined current drawn from the alarm output,
auxiliary power output, and polling loop must not exceed 750mA in order to comply with the battery independence
requirements.
UL1023 Household Burglary Installations
For Household Burglary installations, the total current drawn from the alarm output must not exceed 1.7A. A battery
must be installed, as the battery supplies current from the combined auxiliary power, polling loop, and alarm output in
excess of 750mA.
Non-UL Installations
For non-UL installations, the total current drawn from this output can be up to 1.7A. A battery must be installed, as the
battery supplies current in excess of 750mA. Up to two 719 sirens can be used wired in parallel.
This control complies with National Fire Protection Association (NFPA) requirements for temporal pulse sounding
U L
of fire notification appliances
Alarm Output Supervision
When supervision is enabled, the VISTA-128BPT/VISTA-250BPT monitors the alarm output wiring for open and short
circuit faults while the output is inactive. The system provides a trouble indication (Zone 970) when an open occurs; or
when a short occurs between the Bell (+) and Bell (-) terminal wiring, or between the Bell (+) terminal wiring and earth
ground.
NOTE:
U L When supervising the bell output (zone 970), only one device can be connected to the alarm output
(terminals 4 and 5) for UL and Fire installations.
The VISTA-128BPT/VISTA-250BPT indicates the trouble condition regardless of whether the system is armed or
disarmed. The zone displays on the keypads, reports to the event log, and transmits to the central station (if
programmed) on Partition 1. The Contact ID event code is 321, Bell Trouble. The trouble is cleared from the display by
entering the user code + OFF.
Wiring the Alarm Output
The wiring of the alarm output depends upon whether you are going to supervise the output or not. Use the appropriate
procedure below for your application.
U L
Use only UL Listed sounding devices for UL installations.
