The alarms are associated with cameras by default. There is a panic alarm available using the panic
button on the remote, or on a connected SD keyboard. This will put all cameras into alarm recording.
There is also a contact alarm that is configured as a keyswitch via Alarm input 17.
Alarms support tamper proof detection to detect short circuit, open circuit and contact closure.

This box specifies which alarm response profile is being
configured.
Use the drop down to select whether the contact is normally open
(N/O), normally closed (N/C) or disabled.
The pulse extension is used to prevent double triggers on a single
alarm. The pulse extension time starts on an alarm trigger. If that
contact is triggered again after the first alarm has finished but
within the pulse extension, the second trigger will not restart the
alarm, but will extend the current alarm duration.
The End Of Line (EOL) is part of the advanced alarm feature and
enables the inputs to detect any changes in the input electronic
resistance, e.g. 0 – 800Ω. A change will result in a Tamper Alarm
(short circuit) being detected and the system switching to alarm
mode (refer to 'End Of Line Circuitry' in the 'Installing The SD'
section). By default the EOL contacts are disabled for each input.
An alarm can activate two cameras if required. The primary
camera will take the still image used for e-mailing on alarm
and adding to the event database. It is also the camera that is
displayed first on the Operator monitor.
If the Primary camera is enabled for telemetry, it can be sent on
alarm to the preset nominated here.
If the alarm triggers two cameras, the second camera should
be defined here.
