SERIES HIGH
PERFORMANCE
PIEZO “SCREAMERS”

Model numbers:
MPI-46W, MPI-47, MPI-47B, MPI-47C, MPI-47E

• Five models to meet every
installation requirement:

- MPI-46W (2 sounds) & MPI-47 for

standard wall mount applications

- MPI-47B small and economical with

convenient bracket

- MPI-47C mounts into dropped ceilings

- MPI-47E fits single gang electrical box

• Patented piezo technology provides
more sound with less current

The MPI-46W & MPI-47 “screamers” are a complete
and advanced range of piezo devices. Patented
technology provides a powerful sound output with a
minimum of current consumption. This makes the piezo
“screamer” suitable for use with many of today’s control
panels, even those that provide only limited power for
audible devices.

Unlike a conventional speaker, a piezo is a crystal
type resonator, which provides a broad sound
dispersion and a longer service life. Piezos emit a
piercing high frequency sound, which is very intense
close-up – ideal for smaller houses or stores,
apartments or pre-alarm applications.

The MPI-46W and the MPI-47 are housed in attractive
enclosures for surface mounting. The MPI-47B, 47C
and 47E provide a variety of mounting options:

- MPI-47B is a small round device which can be easily

installed on a wall or a ceiling, using the metal bracket.

- MPI-47C is designed for mounting directly into a

dropped ceiling and includes an attractive circular
faceplate for an easy and neat installation. It can also
be flush-mounted in any wall or ceiling.

- MPI-47E fits directly into a NEMA standard electrical

box of at least 2.0" (5.1 cm) width. A plastic (PVC)
box of 2.0" (5.1 cm) x 3.5" (8.9 cm) is recommended.
If a metal box is used, it should be at least 2.1" (5.3 cm)
wide. The device is fitted with an attractive faceplate.

The MPI-46W provides both a bell and a pulsating
horn sound. The other products in the range provide a
single high/low sound.

Moose MPI-46W and MPI-47 range of piezo “screamers”

The Moose piezo range consists of surface mount models
(MPI-46W & MPI-47), a compact round model on a metal
bracket (MPI-47B), a model for mounting in dropped ceilings
(MPI-47C) and a model for installation in a NEMA standard
electrical box (MPI-47E).
