12.2 Operational parameters

Each burglary protection loop detects three conditions: open, normal, and short.

The parameters for each are listed below:

Condition Resistance on loop Voltage on right 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

12.3 Loop response time

A condition must be present on a loop for 500 milliseconds (1/2 second) before it's detected by the 1912XR

panel. Make sure any detection devices you use on the protection loops are rated for use with this delay.

Loops can also be programmed for a Fast Response delay of 160 milliseconds.

12.4 Keyswitch arming loop (maintained)

Programming a loop as an Arming Type, allows selected areas to arm when the loop is placed into a short

condition. The selected areas disarm when the loop is placed into a normal (1K Ω EOL) condition. If placed

into an open condition from a normal (disarmed ) condition, a trouble is reported. If placed into an open

condition from a short (armed) condition, an alarm is reported and the loop is disabled until another

disarming occurs within the system. The areas controlled by the loop and the relay outputs that indicate

their armed or disarmed status are selected in the panel's Programmer.

Dry Contact Relay Outputs

13.1 Description

Two Form C (SPDT) relay outputs can be provided on the 1912XR by installing two DMP Model 305 relays

into the sockets labeled K9 (Output 1) and K5 (Output 2). Both relays can be operated by the functions

listed below:

1) Activation by loop condition

Steady

Pulsing

Momentary

2) Activation by 24 hour 7 day schedule

One on and one off time a day for each relay

3) Manually from the Security Command keypad User Menu

4) Communication failure output

5) Armed area annunciation

6) Fire Alarm or Fire Trouble

7) Other system conditions. See the 1912XR Programming Manual (LT-0171).

13.2 Contact rating

The DMP 1912XR relay contacts are rated for 1 Amp at 30 VDC or 0.5 Amp at 120 VAC. The auxiliary

output power from terminal 7 can be internally connected to the common terminal of Relay Output 1 by

installing the J15 jumper across both pins.

13.3 Harness wiring

The relay contacts are accessible by installing the DMP 304 Harness on the 10-pin header labeled J2. The

contact locations are shown below:

Contact Color Wire

Output 1 normally closed Violet 10

Output 1 common Gray 9

Output 1 normally open Orange 8

Output 2 normally closed Violet 7

Output 2 common Gray 6

Output 2 normally open Orange 5

The relay contacts must be connected to devices located within the same room as the 1912XR panel.
