Alarm Management - Elkron HP602L Manuel D'installation

•
The siren generates an alarm only when both the TC signal and the block signal are down.
•
The block signal alone is sufficient to stop an alarm in progress.
•
TC1 input can be biased with both positive or negative reference. When the system is in standby, TC1 is tied to its
reference. In alarm condition TC1 is floating, no reference is applied. Should TC1 be biased with its reference
during an alarm cycle, this will cause the siren
•
BL1 input provides a "blocking" command to the siren when its reference is present. Conversely, it will trip an
alarm when reference is removed (at the same time of TC1).
•
After blocking the alarm, the flasher will continue blinking to signal the alarm presence until the TC signal is
received (to deactivate the system).
•
The alarm counter is reset either each time the system is switched off or after 24h from the beginning of the first
sounder operation. Only sounder cycles longer than 25s are considered for this purpose.
•
The sounder counter and the alarm memory are cut off by connecting TC1 and BL1 in parallel.
