Using the CS1050 Expander Board

The CS1050 is a plug-on board that adds an additional 8 inputs and 8 outputs

to the CS1000 and CS2000 range of Dualcom units.

To install:

1. Remove power to the Dualcom when fitting or removing the CS1050 Expander

board.

2. Slide the CS1050 Expander into the two guides on the Dualcom with the

white connector towards the Dualcom board. Push the CS1050 down to

ensure it connects fully to the Dualcom.

3. Connect the triggering inputs to the INPUT terminals labelled 9 to 16, as

required. See page 13 and Appendix 2.

4. Connect the outputs to the OUTPUT terminals, labelled 1 to 8, as required.

These outputs are ‘open collector pull-down to 0v. Each will supply up to

50mA and may operate lights or relays with a supply up to +28 volts. Where

relays are used, they should be fitted with a diode across their coil to reduce

‘back EMF’ voltages. See Fig 7.

Note: If you use a seperate Power Supply, remember to connect the 0v

terminals of all of the parts of the system.

The Dualcom NVM will need to be programmed for ‘16 channels’ enabled. Your

ARC will normally provide a programming service. If a programming service is

unavailable, contact the CSL Technical Support Desk. See page 10.

All of the normal input programming options apply to the CS1050 Expander.

These are: Positive applied / removed triggering, self learning, restore reporting,

open/close reporting, VDN failure report, PSTN failure report and alarm abort.
