The SPP-401 outdoor sounder is used for acoustic alarm signaling. It is designed to operate
in the detection line of the ACSP-402 addressable fire alarm control panel.
1. Features
Acoustic signaling by means of piezoelectric transducer.
Signaling controlled by the control panel:
–different tones for different alarm conditions.
–32 selectable tones.
Double-sided short-circuit isolator.
Power supply from the detection line.
2. Installation
Disconnect power before making any electrical connections.
The sounder is designed for installation outdoors and indoors in places where condensation
of water vapor may occur.
1. Turn the cover counter-clockwise and remove it (Fig. 1).
2. Drill the holes for screws in the enclosure base. Use the countersunk screws (Fig. 2) or
the non-countersunk screws (Fig. 3) to fasten the enclosure base to the wall.
3. Drill the hole(s) for cables in the enclosure base. The markings for the holes are provided
on the bottom (Fig. 4) and on the sides (Fig. 5) of the base. If you drill the holes in the
sides of the base, use cable glands (recommended cable gland: PG-11).
4. Place the enclosure base against the wall and mark the location of mounting holes.
5. Drill the holes for wall plugs (screw anchors) in the wall.
6. Run the cables inside the enclosure base.
7. Use wall plugs and screws to secure the enclosure base to the wall. Select wall plugs
specifically intended for the mounting surface (different for concrete or brick wall, different
for plaster wall, etc.). If you drilled the holes for wires and/or wall plugs on the bottom of
the base, seal them using silicone.
