Installation Procedures
This section contains installation information for PS12/24ADA series
strobes and sounder/strobes. Mounting instructions and wiring
information are provided.
Installation procedures must conform to all applicable codes and the
requirements of the authority having jurisdiction.
For strobe placement, read and be familiar with:
●
NFPA 72-National Fire Alarm Code
Both slotted-head and Phillips-head screws are supplied with the
speaker/strobe.
●
Use the slotted-head screws to mount the semi-flush plate to the
electrical box.
●
Use the Phillips-head screws to attach the PS12/24ADA to a
semi-flush plate or to the electrical backbox.
Note: The rated output of the sounder is specified at ten feet on axis.
It cannot be assumed that the output will meet the NFPA standard
of 15 dB over ambient noise at all locations within a room.
Additional sounders may be needed to ensure that the sound output
level complies with NFPA requirements.
Strobe and sounder/strobe combination are designed for wall mounting
only. The PS12/24ADA is intended for mounting to a standard 2-1/2 inch
deep single gang box which allows for sufficient clearance for conduit
entrance.
All strobes must be mounted where the top of the lens is 24 inches below
ceilings or as required by the authority having jurisdiction.
For mounting the sounder/strobe, note the following figures:
