INSTALLATION
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 13.8VDC and the maximum normal standby current is 1.25mA DC. The maximum
line impedance is 100 Ohms. The maximum short circuit current is 56mA. 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.
Note:
Refer to the Compliance Listing Guide (LT-1330 )for list of compatible DMP 2-wire smoke detectors.
Dry Contact Relay Outputs
12.1 Description
The XR150/XR550 Series panel provides two programmable auxiliary SPDT relays when equipped with two DMP Model
305 relays in sockets K6 (Output 1) and K7 (Output 2) and a Model 431 Output Harness on the J2 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 XR150/XR550 Canadian Series Programming Guide (LT-1232CAN) for specific information.
12.2 Contact Rating
The Model 305 relay contacts are rated for 1 Amp at 30VDC (allows .35 power factor). You can 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.
12.3 Model 431 Output Harness Wiring
The relay contacts are accessible by installing the DMP 431 Output Harness on the 6-pin header labeled J2. Output
2 uses the top three prongs, and Output 1 uses the bottom three prongs. The wire harness and contact locations are
shown below:
