Honeywell 3.5 manual Installing the Control, Using 2-WireSmoke Detectors on Zone, Step Action

Using 2-Wire Smoke Detectors on Zone 1

Zone 1 can support up to 16 2-wire smoke detectors.

The alarm current on zone 1 supports only one smoke detector in the alarmed state.

Figure 3-10: 2-Wire Smoke Detector on Zone 1

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 (750mA).

Auxiliary power to 4-wire smoke detectors is not automatically reset after an alarm, and therefore must be momentarily interrupted using a 4204 Relay Module.

Compatible 4-Wire Smoke Detectors

Use any UL Listed 4-wire smoke detector that is rated for 10-14VDC operation and that has alarm reset time not exceeding 6 seconds. Some compatible 4-wire smoke detectors are listed below.

These smoke detectors are UL Listed for use UL with the VISTA-40 and are the only 2-wire

smoke detectors that may be used.

Wiring 2-Wire Smoke Detectors to Zone 1

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, perform the following steps:

Step Action

1Select up to 16 2-wire smoke detectors from the list of compatible detectors.

2Connect 2-wire smoke detectors across zone 1 terminals (10 and 11) as shown in Figure 3- 10. Observe proper polarity when connecting the detectors.

3Connect 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.

Wiring 4-Wire Smoke Detectors
UL	Power to 4-wire smoke detectors must be
	supervised with an EOL device (use a System

Sensor A77-716B EOL relay module connected as shown in Figure 3-11).

To wire 4-wire smoke detectors to zones 1-8, perform the following steps:

Step Action

1Select 4-wire smoke detectors (see list of compatible detectors shown previously in this section).

2Connect detectors (including heat detectors, if used) across terminals of the zone selected. All detectors must be wired in parallel. See Figure 3-11.

3Connect the EOLR at the last detector in the loop across the zone’s terminals. You must connect the EOLR across the loop wires at the last detector.
