The VALKYRIE AS is a surface mount Addressable sounder with low power consumption available in either Red or White housings. Up to 32 individually addressed sounders can be installed per loop occupying address 94 to 125.
 
When individual address reporting is not required, VALKYRIE AS can be ordered as a Shadow sounder. In this case sounders do not occupy an address in the 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 (10 mA in alarm) and must be included in loop load calculations.
