Section 4. BASIC HARD-WIRED ZONES 1–6
This section provides general information for the hard-wired zones in the
system, plus specific instructions for installing 4-wire smoke/combustion
detectors.
Also included is a procedure for programming the hard-wired zones.
Installing the Hard-Wired Zones
Common Characteristics for Zones 1–6
• Response time from 300 –500 milliseconds (400 milliseconds nominal).
• Zone 3 can be programmed (in field ✱ 52) for normally closed sensor fast
response (10 msec max) to an open (suitable for vibration type contacts).
Default response is 400 msec nominal, which should be used for most
standard contacts.
• EOLR supervised zones support both open-circuit & closed-circuit devices.
• As many 4-wire smoke detectors as can be powered from Aux Power on
the control (on zone 5).
Wiring Burglary and Panic Devices To Zones 1–6
1. Connect sensors/contacts to the hard-wired zone terminals (8 through 16).
See the Summary of Connections diagram .
2. Connect closed circuit devices in series in the high (+) side the loop. The
EOL resistor must be connected in series with the devices, following the
last device. See the Summary of Connections diagram.
3. Connect open circuit devices in parallel across the loop. The 1,000 ohm
EOLR must be connected across the loop wires
at the last device.
If the EOLR is not at the end of the loop, the zone will not be properly
supervised, and the system may not respond to an open circuit on the zone.
Wiring 4-Wire Smoke/Combustion Detectors on Zone 5.
The system will support as many 4-wire detectors as can be powered from
Auxiliary Power on the control on zone 5. Refer to the detector’s instructions
for complete details regarding its proper installation and operation.
1. Connect 12 volt power for the detectors from Auxiliary Power terminals 4
and 5, (which will interrupt power for fire alarm reset). Observe proper
polarity when connecting detectors. See Figure 7.
2. Connect detectors (including heat detectors, if used) across terminals of
zone 5. All detectors must be wired in parallel.
Remove 1000 ohm EOL resistor if connected across the zone terminals. You
must connect the EOL resistor across the loop wires at the last detector.
3. To meet NFPA 72 requirements, you must use a supervisory module to
supervise power (e.g., System Sensor No. A77-716B Relay module).
