Connecting The Transformer - Honeywell VISTA-128BPT Installation And Setup Manual

VISTA-128BPT/128BPT-SIA/250BPT INSTALLATION AND SETUP GUIDE

Connecting the Transformer

This product uses the 1361 or 1361-GT transformer (1361CN or 1361CN-GT in Canada).
NOTE: Upon a total power failure, the control unit will ignore and not transmit alarm supervisory information for a
stabilization period of 120 seconds following restoration of power. Within 60 seconds at the end of the
stabilization period, the control unit shall initiate the transmission of a power restoration signal code. If this
report code is enabled (see report code programming in the Programming Guide), this is the report that will be
sent.
UL
Use 1361CN or 1361CN-GT Transformer in Canadian installations.
Power Limiting Outputs
All outputs are power-limited as per UL985/UL1023. The following table shows the maximum current that may be
drawn from each output.
Output
Auxiliary Power
Polling Loop
Alarm Output
For Household Fire or Combination Household Fire/Burglary Installation: The total current drawn from the
auxiliary power, the polling loop, and the alarm output combined must not exceed 750mA to comply with the battery
independence requirements in UL985.
For Household Burglary-Only Installations: The total current drawn from the alarm output may be up to 1.7A. A
battery must be installed to supply the current of the combined auxiliary power, polling loop, and alarm output in
excess of 750mA.
Failure to observe the polling loop current rating will cause polling loop malfunction. Failure to observe
the auxiliary power current rating will result in a battery that does not charge properly or possibly a tripped
circuit breaker.
To connect the transformer to the control, perform the following steps:
1. Connect all installed devices to the control.
2. Wire the 1361 or 1361-GT Transformer (1361CN or 1361CN-GT in Canada) to the panel (before
connecting the battery) as shown in Figure 35.
3. Plug the transformer into a 24-hour, uninterrupted, 120VAC, and 60Hz outlet. After a few seconds, the
keypad display appears.
