Connecting the Input Alarm devices

You will need to decide how many alarm channels will be utilised. For each alarm channel you

will need a pair of cable connections and it is recommended that a CAT5 twisted pair be utilised.

Connect one core to the selected input alarm channel and the other to the ground (GND)

connection. The ground is a common connection for all four alarm channels. At the alarm end

connect to the alarm device. This must be a 0 volt switch and maybe for example a door switch.

Check that the alarm device passes a voltage free switch as any other input signal may damage

the dome.

Each of the four alarm channels call a different dedicated preset number when the 0v switch is

detected by the dome. This allows the dome to move immediately to the selected preset position

in an alarm condition. The following alarm channels call the stipulated preset number when

activated:

when Alarm Channel No 1 is activated it calls preset number 29

when Alarm Channel No 2 is activated it calls preset number 30

when Alarm Channel No 3 is activated it calls preset number 31

when Alarm Channel No 4 is activated it calls preset number 32.

To set these special presets, if you have set up alarm channel 1, move the dome camera to

where you wish alarm 1 preset to move to, and using the keypad press the preset button

followed by 29. Then if you have set up alarm channel 2, move the dome camera to where

you wish alarm 2 preset to move to, and using the keypad press the Preset button followed by

30 and so on.

When more than one alarm channel is utilised and activated, the dome will respond to each

alarm by calling the relevant preset and switching to the next preset after two seconds. The

dome will lock on to the last alarm activated and will not resume a patrol, auto scan or record

pattern until the alarm condition is cleared or the Alarm Setup options in the dome System

Setup menu are set to restart a tour/patrol etc.

Example: Connecting Alarm 1 channel to a door contact

Here is an example scenario. A company requires a dome to run a patrol (tour) continuously

viewing four preset points. One of the preset points is the main entrance door to the building.

The requirement is to ensure that during out of hours the entrance door is not breached. The

dome alarm 1 channel is connected to a door contact on the main entrance door. A CAT5 twisted

pair is connected at the dome end to the RED Alarm 1 and the BLACK Ground connection on

the dome alarm cable. At the door contact end the twisted pair is connected either way round.

The dome is then set up for a tour using presets 01 to 04 and called TOUR 1. In addition preset

29 is set up focusing the dome camera at the door entrance. When the building is vacated the

dome is left running a tour of the four presets. If the door contact is closed a voltage free switch

is made on the Alarm 1 channel. The dome then automatically calls preset 29 which locks onto

the main entrance door. In the System Setup menu select Alarm Setup, Alarm No., set PATROL

1 in Action menu and switch Alarm to ON. The dome will revert to PATROL/TOUR 1.
