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.
