VISTA-128B Installation and Setup Guide

Installing 2-Wire Smoke Detectors to Zone 1

Zone 1 has the added capability of supporting 2-wire smoke detectors. The zone provides
enough standby current (2mA) to power up to 16 of the smoke detectors listed below. When
assigned zone type 9, the second entry of a User Code + OFF sequence at a keypad will
interrupt power to these zones to allow detectors to be reset following an alarm.
Compatible 2-Wire Smoke Detectors
You may use up to 16 2-wire smoke detectors on zone 1 listed in the table below.
DETECTOR TYPE
Photoelectric, direct wire
Photoelectric w/heat sensor,

These smoke detectors are UL Listed for use with the VISTA-128B and are the only 2-wire
U L
smoke detectors that may be used.
