VISTA-128FBP/VISTA-250FBP Installation and Setup Guide

3-12

• These smoke detectors are UL Listed for use with the VISTA-128FBP/VISTA-250FBP and are the only 2-

wire smoke detectors that may be used.

• A combination of heat detectors and smoke detectors is not permitted on a zone programmed for fire

verification.

• Fire installations require the use of a synchronization module to synchronize the sounders and strobes on

the system.

Wiring 2-Wire Smoke Detectors to Zones 1 and 2

2K EOL resistors must be used on fire zones and must be connected across the loop wires of each zone at the

last detector.

To wire 2-wire smoke detectors to zone 1 and/or zone 2, perform the following steps:

Step Action

1 Select 2-wire smoke detectors from the list of compatible detectors.

2 Connect 2-wire smoke detectors across zone 1 (terminals 15 and 16), and/or zone 2 (terminals 17 and 18) as

shown in Figure 3-10. Observe proper polarity when connecting the detectors.

Connect the EOL resistor at the last detector in the loop across the zone 1 terminals. The EOL resistor

must be connected across the loop wires at the last detector.

Using 4-Wire Smoke Detectors on Zones 1-8

You may use as many 4-wire smoke detectors as can be powered from the panel's Auxiliary Power output without

exceeding the output's rating (1A).

Auxiliary power to 4-wire smoke detectors is not automatically reset after an alarm, and therefore must be

momentarily interrupted using the auxiliary relay.

Compatible 4-Wire Smoke Detectors

Use any UL Listed 4-wire smoke detector that is rated for 12VDC operation and that has alarm reset time not exceeding

6 seconds. Some compatible 4-wire smoke detectors are listed below.
