Section 5. BASIC HARD-WIRED ZONES 1-5
This section provides the following information:

• General information about hardwired zones

• Installing 2-wire smoke detectors
• Installing 4-wire smoke/combustion detectors
• Programming hardwired zones
• Checkout procedure for hardwired zones
General Information about Hardwired Zones
Provides 5 Style B supervised hardwired zones having the following
characteristics:
• EOLR supervision supporting N.O./N.C. contacts from a listed fire alarm
• 300 – 500ms response time
• Individually assignable to bell output and/or aux. relay
• Supports up to 16 2-wire smoke detectors on Zone 5
• Supports 4-wire smoke detectors on any zone (power to these should be
• Tolerance of 300-ohms on Zones 1-4, 100-ohms on Zone 5 (excluding EOLR)

Wiring Devices To Zones 1-5

1. When used as a slave DACT for a listed FACP, wire the FACP's alarm,
2. Connect closed circuit devices in series in the high (+) side the loop. The
3. Connect open circuit devices in parallel across the loop. The 2,000 ohm EOL
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 Zones 1-5

The system will support as many 4-wire detectors as can be powered from
Auxiliary Relay Power on the control. 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 Relay Power
2. Connect detectors (including heat detectors, if used) across zone terminals.
control panel or N.O./N.C. sensors, including:
– fire alarm sensors (N.O. only)
– 24-hr. alarm sensors
– fire sprinkler supervisory sensors
supplied from the control's aux. relay power output; see "Installing 4-Wire
Smoke Detectors" later in this section).
supervisory and trouble contacts to the 5110XM's hardwired zones
(terminals 9-16). Fire alarm initiating devices such as smoke detectors
should be wired to the FACP and not the 5110Xm. When used as a stand
alone control, wire alarm initiating devices to the 5110Xm's hardwired
zones. See the summary of connections diagram.
2,000 ohm EOL resistor must be connected in series with the devices,
following the last device. See the Summary of Connections diagram.
resistor must be connected across the loop wires at the last device.
terminals 7 (+) and 18 (-). Be sure to program the Aux Power Relay for the
smoke detector reset function in program field *34. Observe proper polarity
when connecting detectors.
All detectors must be wired in parallel with the 2,000 ohm resistor wired in
parallel at the last device in the loop.
