Bell Output, Keypad Data Bus | DMP Electronics LT-0229 (5 97)

Installation

Bell Output

7.1Terminals 5 and 6

Nominal 12 VDC is supplied by terminal 5 on the panel to power alarm bells or horns. The output is rated for a maximum output of 1.5 Amps. This output can be steady or pulsed depending upon the Bell Action specified in Output Options. Terminal 6 is the ground reference for the bell circuit.

Keypad Data Bus

8.1Description

Terminals 7, 8, 9, and 10 of the XR10/XR20 panel are designated as the keypad data bus. In addition to keypads, the XR20 allows the connection of any combination of zone expanders, 5845LX Glassbreak Detectors, 6155LX PIRs, and DS775LX PIRs to the data bus up to the maximum of four devices.

8.2Terminal 7 - RED

Nominal 12 VDC is supplied at terminal 7 to power Security Command keypads and zone expanders. This is also where power for any auxiliary device is supplied. The ground reference for terminal 7 is terminal 10. The maximum output is rated at 500mA. All auxiliary devices totalled together must not exceed the panel's maximum current rating of 500mA.

8.3Terminal 8 - YELLOW

Data receive from keypads and zone expanders.

8.4Terminal 9 - GREEN

Data transmit to keypads and zone expanders.

8.5Terminal 10 - BLACK

Terminal 10 is the ground reference for Security Command keypads, zone expanders, and any auxiliary devices being powered by terminals 7 and 11.

Smoke and Glassbreak Detector Output

9.1Terminal 11

Nominal 12 VDC at 100mA maximum (shared by terminal 25) is supplied at terminal 11 to power 4-wire smoke detectors or other auxiliary powered devices. This output can be turned off by the user for 5 seconds using the Sensor Reset Menu Option. Terminal 10 is the ground reference for terminal 11.

Burglary Zones

10.1Description

Terminals 12 to 24 are the nine burglary zones. For programming purposes, the zone numbers are 1 to 9. The zone configurations on terminals 12 to 24 are described below.

Terminal	Function	Terminal	Function
12	Zone 1 voltage sensing	19	Ground for zones 5 & 6
13	Ground for zones 1 & 2	20	Zone 6 voltage sensing
14	Zone 2 voltage sensing	21	Zone 7 voltage sensing
15	Zone 3 voltage sensing	22	Ground for zones 7, 8, & 9
16	Ground for zones 3 & 4	23	Zone 8 voltage sensing
17	Zone 4 voltage sensing	24	Zone 9 voltage sensing
18	Zone 5 voltage sensing

The voltage sensing terminal measures the voltage flowing through the 1k Ω End Of Line resistor to the zone's ground terminal. Dry contact sensing devices can be used in series (normally-closed) or in parallel (normally- open) with any of the burglary protection zones.
