Section 6: BASIC HARDWIRED ZONES 001-008
This section provides the following information:
• Common characteristics of hardwired zones
• Wiring burglary and panic devices to zones 1-8
• Wiring 2-wire smoke detectors to zones 1 and 2
• Wiring 4-wire smoke detectors to zones 1-8
• Compatible smoke detectors (2- and 4-wire)
• Wiring 2-wire glassbreak detectors to zone 8
• Check-out procedure for hardwired zones
Common Characteristics of Hardwired Zones 1-8
• EOLR supervision (optional for zones 3-8) supporting N.O. or N.C. sensors
(EOLR supervision required for fire and UL Burglary installations)
• Individually assignable to one of 8 partitions
• Up to 16 2-wire smoke detectors each on zones 1 and 2 (32 total)
• 4-wire smoke or heat detectors on zones 1-8 (power to 4-wire smokes must
be supervised with an EOL device)
• Up to 50 2-wire latching glassbreak detectors on zone 8
• Individually assignable to bell outputs and/or aux. relay
Wiring Burglary and Panic Devices to Zones 1-8
1. Connect sensors/contacts to the hardwire zone terminals (15 through 27).
• Connect N.C. devices in series with the high (+) side of the loop. The
2K EOL resistor must be connected in series with the devices,
following the last device.
• Connect N.O. devices in parallel (across) the loop. The 2K EOL resistor
must be connected across the loop wires at the last device.
The maximum zone resistance is 100 ohms for zones 1, 2 and 8, and 300 ohms
for all other zones (excluding the 2K EOL resistor).
Wiring 2-Wire Smoke Detectors to Zones 1 and 2
Zones 1 and 2 have the added capability of supporting 2-wire smoke detectors.
Each zone provides enough standby current (2 mA) to power up to sixteen of the
smoke detectors listed below. Each zone provides only enough alarm current
(20 mA) to power one smoke detector in the alarmed state. When assigned
zone type 9 or 16, the second entry of a User Code + OFF sequence at a keypad
will interrupt power to these zones to allow detectors to be reset following an
alarm.
1. Connect 2-wire smoke detectors across zone 1 and/or zone 2 terminals (15
through 18) as shown in Figure 6. Observe proper polarity when connecting
the detectors.
2. If EOL resistors are presently connected across zone 1 and zone 2 terminals,
remove them. The EOL resistors must be connected across the loop
wires of each zone at the last detector.
610-7 2K EOLR resistors must be used on fire zones (standard, discrete 2K
EOLR resistors may be used on burglary and panic zones).
3. See “Programming Hard-Wired Zones” later in this section for a detailed
programming procedure.
