INSTALLATION
10.3 Zone Response Time
A condition must be present on a zone for 400 milliseconds before it is detected by the XR150INT/XR550INT
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 13.8 VDC and the maximum normal standby current is 1.25 mA DC. The
maximum line impedance is 100 Ohms. The maximum short circuit current is 56mA.
When using zone expansion modules, use Model 309 EOL resistors. The compatibility identifier 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.
Dry Contact Relay Outputs
12.1 Description
The XR150INT/XR550INT Series panel provides two programmable auxiliary SPDT relays when equipped
with two DMP Model 305 relays in sockets OUTPUT 1 and OUTPUT 2 and a Model 431 Output Harness on the
OUT1-OUT2 6-pin Header. Each relay provides one SPDT set of contacts that can be operated by any of the
functions listed below:
1) Activation by zone condition: Steady, Pulsing, Momentary, and Follow
2) Activation by 24-hour 7-day schedule: One on and one off time a day for each relay
3) Manual activation from the DMP LCD keypad menu
4) Communication failure
12) Ready
5) Armed area annunciation
13) Armed
6) Fire Alarm, Fire Trouble or Supervisory
14) Disarmed
7) Ambush Alarm
15) Burglary
8) Exit and Entry timers
16) Phone Trouble
9) System Ready
17) Device Fail
10) Late to Close
18) Sensor Reset
11) Panic Alarm
19) Closing Wait
Refer to the XR150INT/XR550INT Series Programming Guide (LT-1232INT) for specific information.
12.2 Contact Rating
The Model 305 relay contacts are rated for 1 Amp at 30VDC (allows .35 power factor). Connect auxiliary
power to the Relay Output 1 common terminal by installing the gray harness wire to terminal 7. Current
draw for all connected devices must not exceed the panel maximum current rating.
