Compatible 2-Wire Smoke Detectors; Wiring 4-Wire Smoke Detectors To Zones 1-8 - ADEMCO VISTA-32FB Installation And Setup Manual

Compatible 2-Wire Smoke Detectors

Zone 1 and zone 2 may each contain up to 16 2-wire smoke detectors. A list of approved
smoke detectors are contained in the following table.
DETECTOR TYPE

These smoke detectors are UL Listed for use with the VISTA-32FB and are the only 2-wire
U L
smoke detectors that may be used.

Wiring 4-Wire Smoke Detectors to Zones 1-8

When programmed for fire warning usage, all zones can monitor 4-wire smoke detectors
(zone types 9, 16), N.O. fire alarm initiating devices (zone types 9, 17), or N.O. sprinkler
system supervisory devices (zone type 18).
The installer may use as many 4-wire smoke detectors as can be powered from the panel's
Auxiliary Power 1 output without exceeding the output's rating (see Section 19: Final Power-
Up Procedure for auxiliary power ratings).
Auxiliary power to 4-wire smoke detectors is not automatically reset after an alarm. It must,
therefore, be momentarily interrupted using the built-in auxiliary relay as described below. This
allows the detectors to be reset via the second entry of a [User Code] + [OFF] sequence. Field
3 61 Aux Relay Function must be programmed as a 2.
1. Connect 12-volt power for the detectors as follows: Wire the [+] side of Auxiliary Power
(Terminal 10) to the N.C. contact of the Aux. Relay (Terminal 9). Wire the Pole of the
Aux Relay (Terminal 8) to the [+] Power side of the smoke detector. Connect the [-] side
of the smoke detector to [-] Aux. Power (Terminal 12). Observe proper polarity when
connecting detectors (see Figure 6-2).
Power to 4-wire smoke detectors must be supervised with an EOL device (use a System Sensor
U L
A77-716B EOL Relay Module connected as shown in Figure 6-2 ).
