Installing External Sounders; Figure 3-5: Using A Supplementary Power Supply - Honeywell VISTA-128BPEN Installation And Setup Manual

Vista-128BPEN Installation and Setup Guide
Supplementary Power Supply for Additional Keypads
When the control's auxiliary power load for all devices exceeds 750mA, you can power additional keypads from a
regulated 12VDC power supply (e.g., ADEMCO AD12612 (1.2A)). Use a UL Listed, battery-backed supply for UL
installations.
Connect the additional keypads as shown in Figure 3-5, using the keypad wire colors shown. Be sure to observe the
current ratings for the power supply used.
• Make connections directly to the screw terminals as shown in Figure 3-5 . Make no connection to the blue wire (if
present).
• Be sure to connect the negative (–) terminal on the power supply unit to terminal 7 (–) on the control.

Installing External Sounders

The VISTA-128BPEN 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 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. If, for example, two System Sensor MH piezo alarm sounders, wired in parallel, are used (24mA total),
then 726mA (750mA – 24mA) is available for auxiliary output and polling loop use.
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.
