Nortech Addressable Wall Mount Sounder/Beacon
د.إ99.00
The NGA-504 ASB is a wall mounted Addressable Sounder /
Beacon with low power consumption. Up to 32 individually
addressed sounders can be installed per loop occupying
address 94 to 125. The address is set using switches 1 to 5 of
the 8 way DIL switch. Four different tones are available and
selected using DIL switches 6 and 7.
SPECIFICATION
When individual address reporting is not required, NGA-504 ASB can be configured as a Shadow
sounder. In this case sounders do not occupy and address i nthe loop thus freeing up addresses for
more detection devices. Shadow sounders do not report back to the control panel so their presence on
the loop is not monitored. Shadow sounders draw current from the loop (10mA in alarm) and must be
included in loop load calculations.
