Common Characteristics of Hardwired Zones 1-9
EOLR supervision (optional for zones 2-8) 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 zone 1
4-wire smoke or heat detectors on zones 1-8 (power to 4-wire smoke detectors must be
supervised with an EOL device)
Up to 50 2-wire latching glassbreak detectors on zone 8
Wiring Burglary and Panic Devices to Zones 1-9
1. Connect sensors/contacts to the hardwire zone terminals (10 through 23). See
Figure 6-1
.
2. 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.
3. 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 and 8, and 300 ohms for all other zones
(excluding the 2K EOL resistor).
