Digital Monitoring Products Inc PC0096 User Manual

Nominal 12 VDC is supplied by terminal 5 on the panel to power alarm bells or horns. The output is rated

for a maximum of 1.5 Amps with a 40 VA transformer. This output can be steady, pulsed, or Temporal Code 3

depending upon the Bell Action specified in Output Options programming. Terminal 6 is the ground reference

for the bell circuit. If using a horn or siren, a 1k 0hm 1/2W resister should be added across the bell circuit

for supervision.

Terminals 7, 8, 9, and 10 of the panel are designated as the keypad data bus. In addition to keypads,

the XT30/XT50 allows the connection of any combination of zone expansion modules, 5845LX Glassbreak

Detectors, and 6155LX PIRs to the keypad bus up to the maximum of five devices.

Nominal 12 VDC is supplied at terminal 7 to power 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 totaled together must not exceed the Terminal 7 maximum

current rating of 500mA.

Data receive from keypads and zone expanders.

Data transmit to keypads and zone expanders.

Terminal 10 is the ground reference for LCD keypads, zone expanders, and any auxiliary devices being

powered by terminals 7 and 11.

A locking 4-pin header (J8) is provided to connect a keypad when using a DMP Model 330 Programming Cable.

This provides a quick and easy connection for programming the panel.

Keypad Bus expansion zones are numbered in groups of four corresponding to the address. Example: address

1 is zones 11-14 and address 5 is zones 51-54. There are a maximum of 20 zones possible on the Keypad Bus.

All keypad zones terminate with a 1k 0hm EOL resister.

The Overcurrent LED (OVC) lights Red when the devices connected to the Keypad Bus and LX-Bus(es) draw

more current than the panel is rated for. The OVC is located above Outputs 1 and 2 on the panel and turns a

steady Red when lit. When the OVC LED lights Red, the LX-Bus(es) and Keypad bus are shut down.

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 option in the User Menu. Terminal 10 is the ground reference for terminal 11.
