C. ALARM OPERATION
When an alarm is activated, the associated camera video displays full screen, the word ALARM
displays on screen, a buzzer, if programmed "30 SEC", generates a continuous audible alarm for 30 seconds and
the alarm output relay activates.
If the second or third sensor is activated while the first alarm is operating, the screen will switch to the second or
third sensing camera. Pressing the VCR KEY resets the alarm condition.
*When connected to a time lapse VCR, the VCR will automatically switch to the normal mode when an alarm is
sensed. If the VCR was programmed (ex:24hrs, 72hrs then the VCR will automatically switch back once the alarm
is released.
(1) ALARM INPUT specification (Normally in “H” state due to FULL UP resistance of the MULTIPLEXER itself.)
(2) ALARM OUT specification.
The points of contact of RELAY are used as output (HOT/COLD, no polarity), and the points of contact are
open (NORMAL OPEN) during normally. However, the points of contact are closed (MAKE) during HOLD TIME
resulted from ALARM occurred.
The specification of points of contact is 5A 250VAC (Avoid connecting with the product that has higher capacity
than the specification).

To cancel ALARM, press any one of CH1~4, QUAD, AUTO, LIVE/PB, ZOOM, PB THRU, and FREEZE keys.
ALARM is canceled even if ALARM HOLD TIME is in progress.
The date, time and channel ALARM occurred are stored in the ALARM/LOSS LIST.
BUZZER sounds during ALARM HOLD TIME specified in ALARM MENU. ALARM and BUZZER sound
