3.Alarm inputs will be programmed in the Programming section for normally open or normally closed operation.

Normally closed operation = current flow = alarm switch or relay closed Normally open operation = no current flow = alarm switch or relay open

In the example in Figure 8, current flows through the contacts (switch) in the door when it is closed. When the door is open, no current flows. To cause an alarm when the door is opened, program the alarm input for normally closed (door is normally closed). To cause an alarm when the door is closed, program the alarm input for normally open (door is normally open).

4.If your VCR has an alarm input to change the VCR to its alarm recording speed when the multiplexer receives an alarm, connect the VCR alarm input to the normally open (NO) relay contact on the multiplexer. Connect a wire from the relay’s common (C) connection to ground on the VCR.

Proceed to the Powering the Multiplexer section.

POWERING THE MULTIPLEXER

It is recommended that multiplexers being powered up for the first time or after extended storage be initialized using the following procedure. This will clear any random data remaining in the multiplexer and initialize the memory for user programming.

1.Turn on power to your cameras, monitors, and any other equipment that is connected to the multiplexer.

2.Plug in one end of the power cord into the multiplexer.

3.Press and hold the VIEW button on the front panel of the multiplexer while you plug the power cord into an electrical outlet. When the Initialization Menu appears, release the VIEW button. The monitor will indicate PLEASE WAIT and begin a 20-second countdown. When the countdown has been completed, the Initialization Menu will disappear, all programming menus will be at their default settings, and the multiplexer will be ready for use.

If you are installing your system with a KBD4000 keyboard or MX4000SVR Multiplexer Server, proceed to the appropriate section for further installation instructions.

MULTIPLEXER WITH KBD4000 KEYBOARD

Refer to Figure 2 in the Applications section for an overview of a typical installation.

1.Follow the instructions in the Basic Installation section to mount the multiplexer; to connect cameras, monitors, VCR, and alarms; and to power-up the multiplexer.

2.A maximum of 16 multiplexers can be daisy-chained together. If you are going to daisy-chain multiplexers, use the 6-foot (1.8 m) data cables that are supplied with the multiplexers. Connect a cable from the COM OUT port of the first multiplexer to the COM IN port of the second multiplexer, then connect the COM OUT port of the second multiplexer to the COM IN port of the third multiplexer, etc.

3.Proceed to the KBD4000 Genex™ Multiplexer Keyboard Installation/Operation Manual to complete the installation, which involves setup and connection of the KBD4000 keyboard, and programming the multiplexer.
