Figure 3-13: 4-Wire Smoke Detectors - Honeywell VISTA-32FBPT Installation And Setup Manual

Wiring 4-Wire Smoke Detectors
Power to 4-wire smoke detectors must be supervised with an EOL device (use a System Sensor EOLR-1 EOL
•
U L
relay module connected as shown in Figure 3-13).
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.
To wire 4-wire smoke detectors to zones 1-8 or polling loop expansion module zones, perform the following steps:
Step Action
1 Select 4-wire smoke detectors (see list of compatible detectors shown previously in this section).
2 Connect detectors (including heat detectors, if used) across terminals of the zone selected. All detectors must
be wired in parallel. See Figure 3-13.
3 Connect 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.

Zone 6 Tamper Configuration
Zone 6 may be used as a tamper loop for the VISTA-32FBPT Cabinet Door Tamper Switch.
Assign zone 6 to a burglary partition. Program it for day trouble/night alarm (zone type 5) when only one burglary
partition is used. Program it for 24-hr. audible alarm (zone type 7) when more than one burglary partition is used.
Enable the Zone 6 Alternate Tamper Function (program field 3∗17).
Tamper Supervision for the Hardwired Zones
The system can be programmed to monitor for either an open condition or a short condition of a tamper switch on zones
1-8. End-of-line supervision is required for this option.
Wiring a Tamper Switch to Zones 1-8
The wiring of the tamper switch depends on whether the tamper switch and the sensor are normally open or normally
closed.
If you are using a normally closed sensor, the tamper switch must be normally open. Refer to Figure 3-14 for
•
the wiring configuration.
If you are using a normally open sensor, the tamper switch must be normally closed. Refer to Figure 3-15 for
•
the wiring configuration.
To wire a tamper switch on a hardwired zone, connect the EOL resistor at the last detector in the loop across the zone's
terminals. You must connect the EOL resistor at the last detector for proper operation of the tamper
supervision.
NOTE: For the normally closed sensor, program the zone for trouble on short. For the normally open sensor,
program the zone for trouble on open.
NOTE: For zones with a response type of 9 or 16 (Fire), the tamper selection must be "0" none.
