Honeywell VISTA 20P, VISTA-20PSIA, VISTA-15P, VISTA-15PSIA Mounting and Wiring the Control, Zones

	Mounting and Wiring the Control
Smoke Detector Notes	• Fire Verification (zone type 16): The control panel will “verify” a fire alarm by
	resetting the smoke detectors after the first alarm trigger, and then waiting 90 seconds
	for a second alarm trigger. If the smoke detector or thermostat does not trigger again,
	the control will disregard the first trigger, and no alarm signal will occur. This feature
	eliminates false alarms due to electrical or physical transients.
	SIA Installations: If using fire verification on zones other than zone 1, UL Fire Alarm
	Listed relay accessories must be used to reset power as described in the Power Reset
	paragraph above.

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

•Clean Me Option: If enabled (field *174 = 1; *56 zone programming, response time prompt = 3), certain ESL smoke detectors send “clean me” reports as appropriate. If used, the maximum number of detectors is reduced to 10 (not standard 16). Refer to the ESL documentation included with the smoke detector for information regarding compatibility with the clean-me option.

•Do not use 4-wire smoke detectors on zone 1.

4219/4229 Expansion	1. Connect each module to the control’s keypad terminals and set the device addresses.
Zones	• VISTA-20P: Up to 40 expansion zones using up to 5 Zone Exp. Modules.

•VISTA-15P: Up to 16 expansion zones using up to 2 Zone Exp. Modules.

2.Connect sensors to the module’s loops. See Figure 8 on the following page.

• Use 1000 ohm end-of-line resistors at the end of loops connected to the 4219/4229 modules. (EOLRs used on the control terminals are 2000 ohms.)

• Expansion zones have normal response time (300–500 msec), except zone connected to each module’s loop “A,” which can be set for fast response (10–15 msec).

3.If using relays with the 4229, connect the desired field wiring to the unit's relay contact terminals.
