© Smoke Detector Notes 4219/4229 Expansion Zones Mounting and Wiring the Control • 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 up to 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. +5 AUX PWR OUTPUT TERMINALS _ PROGRAM RELAY AS ZONE TYPE 54 (FIRE ZONE RESET) 4 CONTACT OPENS MOMENTARILY UPON FIRE ALARM RESET RELAY BLK _ + N.O.

Connect each module to the control's keypad terminals and set the device addresses. See the Table of Device Addresses to select an appropriate address for each module. • 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. © © 2-7
