The alarm package may be enabled/disabled via a keyswitch fitted

across alarm contacts pins 1 and 2. When the switch is closed the alarm

package is disabled, opening the switch and the alarm package is active.

This may be used to control the alarm package, i.e. enabled at night

when the building is empty etc.

Note that cutting the switch cable will activate the alarm package.

Action on alarm

Each alarm can be programmed to switch monitor 1 to display a specific camera and goto a pre-set position for that

camera. An alarm message is displayed on the screen and the alarm output relay closes for a programmed length of

time.

If the sequence is running then the alarm time is added to the sequence time and the sequence continues to run after

the alarm times out. If the sequence is not running the alarm message and selected camera remain on monitor 1 until

a manual camera selection.

The camera selected and the pre-set command issued is programmable via the keypad, press the program key and

follow the on screen commands.

The length of time the contacts close is also programmable. Press the program key and follow the instructions on the

screen

To disable the program key remove the shorting link from the small rectangular slot below monitor 2 output

To use the goto pre-set feature you must have fitted Rx400P or Rx400DC receivers and pre-set PTZ heads.

Alarms and the BBV Rx100 dome interface, Rx400DC high/variable speed DC receiver.

These receivers have 4 & 8 local alarm inputs respectively and a single normally closed relay output that opens

momentarily when a local alarm is activated. This output can be wired to an alarm input on the Tx1000.

A receiver local alarm will cause the relevant pre-set position to be automatically selected without the intervention of a

telemetry transmitter, see the receiver installation guide. If the transmitter also generates a goto pre-set command,

then the receiver’s goto pre-set will be overruled. To overcome this, alarm pre-set 16 now becomes a special that

disables a goto pre-set command.

If the local alarm feature of any receiver is used then set the alarm pre-set position to 16 from the Tx1000 menu.

The standard AC Rx400P receiver can be programmed to goto pre-set position 1-15 during an alarm.

If you require to call preset 16 then software is available from BBV.

If at all unsure, please call BBV for assistance.
