Protection Zones
10.1 Terminals 13–24
Zones 1 to 8 (terminals 13 to 24) on the XR500 Series 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.
Terminal Function Terminal Function
13 Zone 1 voltage sensing 19 Zone 5 voltage sensing
14 Ground for Zones 1 and 2 20 Ground for Zones 5 and 6
15 Zone 2 voltage sensing 21 Zone 6 voltage sensing
16 Zone 3 voltage sensing 22 Zone 7 voltage sensing
17 Ground for Zones 3 and 4 23 Ground for Zones 7 and 8
18 Zone 4 voltage sensing 24 Zone 8 voltage sensing
The voltage sensing terminal measures the voltage across 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 Series 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.
The maximum voltage is 14 Vdc and the maximum normal standby current is 1.25mA DC. The maximum line
impedance is 100 Ohms. The maximum short circuit current is 56mA.
When using all other zone expansion modules, use listed Model 309 EOL resistors. The compatibility identier
for the zones is A.
Note: Do not mix detectors from dierent manufacturers on the same zone.
Caution: Performing a Sensor Reset momentarily drops power to the devices on Terminal 11 (SMK), Zones 9
and 10. The panel views these zones (9 and 10) as “Open” while the power is absent.
