Figure 3-11: 4-Wire Smoke Detectors - Honeywell VISTA-128BPEN Installation And Setup Manual

Power to 4-wire smoke detectors must be supervised with an EOL device (use a System Sensor EOLR-1 EOL relay
U L
module connected as shown in Figure 3-11 ).
To wire 4-wire smoke detectors to zones 1-8, perform the following steps:
Step Action
1 Select 4-wire smoke detectors (see list of compatible detectors shown previously).
2 Connect detectors (including heat detectors, if used) across terminals of the zone selected. All detectors must
be wired in parallel. See Figure 3-11.
NOTE: If you are using the J7 output trigger to reset the smoke detectors, refer to Smoke Detector Reset later
in this section for the wiring instructions.
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.

Using 2-Wire Latching Glassbreaks on Zone 8
Zone 8 can support 2-wire glassbreak detectors. The zone provides enough standby current to power up to 50 2-wire
glassbreak detectors meeting the requirements listed below.
Compatible Glassbreak Detectors
Use detectors that meet the following ratings:
Standby 5VDC–13.8VDC
Voltage:
Standby Greater than 20k ohms (equivalent
Resistance: resistance of all detectors in parallel)
Alarm Less than 1.1k ohms (see note below)
Resistance:
Alarm 2mA–10mA
Current:
Reset Time: Less than 6 seconds
NOTES:
•
You can use detectors that exceed 1.1k ohms in alarm, provided they maintain a voltage drop of less than 3.8 volts in
alarm.
•
The ADEMCO ASC-SS1 detector has been tested and found to be compatible with these ratings.
