The shelf alarm panel telco alarm interface relay circuits are capable of carrying
60 VDC or 1 A with a max. rating of 30 VA. The shelf alarm panel accepts timed
pulse inputs for clearing minor and major alarm states. Reset is accomplished by
asserting a voltage differential from 3.3 V to 48 V for between 200 and 300 ms.
The acceptance voltage range is from 0 to 48 VDC continuous (handles up to 60
VDC at a 50% duty cycle). The current drawn by a reset input does not exceed 12
mA.
The alarm LED reset button activates the alarm cutoff (ACO) state for major,
minor, and user-defined alarms. You cannot reset critical alarms with the alarm
LED reset button.
When the ACO state is activated, active alarm LEDs blink and all of the alarm
relays are deactivated. The alarm reset button activates the ACO state but does
not clear the alarm completely.
