Protection Zones
10.1 Terminals 13–24
Zones 1 to 8 (terminals 13 to 24) on the XR500/XR500N panel are all grounded burglary zones. For programming
purposes, the zone numbers are 1 through 8. Listed below are terminal 13 to 24 connection functions.

Zone 8 voltage sensing
The voltage sensing terminal measures the voltage through a 1k Ohm End-of-Line resistor to ground. Use DMP Model
311 1k Ohm resistors. Dry contact sensing devices can be used in series (normally-closed) or in parallel (normally-
open) with any of the burglary protection zones.

10.2 Operational Parameters
Each protection zone detects three conditions: Open, Normal, and Short. Listed below are voltage and resistance
parameters for each condition:
Condition
Resistance on zone
Voltage on positive terminal
Open
over 1300 ohms
over 2.0 VDC
Normal
600 to 1300 ohms
1.2 to 2.0 VDC
Short
under 600 ohms
under 1.2 VDC
10.3 Zone Response Time
A condition must be present on a zone for 500 milliseconds before it is detected by the XR500/XR500N panel.
Ensure detection devices used on the protec tion zones are rated for use with this delay. Zones 1-10 can also be
programmed for a fast response delay of 160 milliseconds.
10.4 Keyswitch Arming Zone
Using a keyswitch on an Arming type zone allows you to arm and disarm selected areas without having to enter a
user code.
Powered Zones for 2-Wire Smoke Detectors
11.1 Terminals 25–26 and 27–28
Panel terminals 25 through 28 provide two resettable Class B, Style A, 2-wire powered zones. For programming
purposes the zone numbers are 9 and 10.
Note
: The maximum wire length for either zone 9 or zone 10 is 3000 feet using 18 AWG or 1000 feet using 22 AWG.
When using 725 Zone Expansion Modules, use UL Listed Model 316 EOL resistors. The UL compatibility identi
Þ
er for
the zones using 725 Zone Expansion Modules is B. When using all other zone expansion modules, use UL Listed Model
309 EOL resistors. The UL compatibility identi
Þ
er for the zones is A.
Note
: Do not mix detectors from different manufacturers on the same zone.
Caution
: Performing a Sensor Reset momentarily drops power to the devices on Zones 9 and 10. The
panel views these zones (9 and 10) as “Open” while the power is absent.
