Alarm I/O Setup
The Alarm In setting options are NO (Normally Open), NC (Normally Closed), or OFF. The
Alarm Out setting options are AH (Active High) or AL (Active Low) TTL output. The Exit
option saves the changes and returns to the Alarm Setup menu.
Alarm Action Setup
There are two screens for the Alarm Action Setup as shown below. The Next and Back
buttons toggle between the two screens. The Exit button saves the settings and returns to
the main Alarm Setup menu.
Buzzer: When set to ON, the multiplexer’s internal buzzer sounds upon an alarm
condition.
Alarm Screen: When set to ON, the screen display changes to the one defined in the
Alarm Screen Format menu during an alarm condition.
Network Relay: When set to ON, the multiplexer sends the alarm information to an
external relay box via the network during an alarm condition.
Message Latch: When set to ON, an “A” displays on the screen when an alarm
conditions occurs. It remains on the screen until it is cleared.
Recording: This allows the user to select how video will be recorded during an alarm
condition. INT interleaves images from the camera with an alarm every other field,
thereby providing more images from the camera. When there are multiple alarms, the
cameras with alarms are interleaved. The ONLY option records images from only the
camera with an alarm condition. UNC leaves the recording parameters unchanged.
