DESCRIPTION
The Fenwal Series MIZ piezoelectric Mini Horns are
compact electronic alarm signals that are listed under UL
464 for Audible Appliances in public mode Fire Protection
Systems. They are ideal for alarm signaling in individual
rooms, apartments, hotels, motels and offices where
attractive appearance dependable performance and economical installation are prime concerns.
The MIZ-TC models offer field selectable setting for Temporal (Code 3) or Continuous Horn along with an attractive appearance and dependable performance. The
Series MIZ offers high sound output along with low current draw and are available with color choices of red or
off-white which will blend with any decor.
The Series MIZ signals are rated for 24 Vdc input and
may be used with filtered or unfiltered (full-wave-rectified)
input voltages. The Series MIZ Signals have IN/OUT wiring terminations that accept two #12 to #18 AWG wires at
each terminal. Inputs are polarized for compatibility with
standard reverse polarity type supervision.

instructions could result in improper installation, application, and/or operation of
these products in an emergency situation,
which could result in property damage and
serious injury or death.
1.
Mini Horn models are listed for indoor use with a
temperature range of 32°F to 120°F (0°C to 49°C)
and maximum humidity of 85% RH.
2. Rated input voltage (either filtered DC or unfiltered
full-wave-rectified FWR): 18-31 Vdc (for 24 Vdc MIZ
models) and 16-33 Vdc (for 24 Vdc MIZ-TC models).
3. Contact Fenwal for Installation Instructions on these
products. These materials contain important information that should be read prior to specifying or
installing these products including:
• Total current required by all appliances connected to system secondary power sources.
• Fuse ratings on notification appliance circuits to
handle peak currents from all appliances on
those circuits.
• The voltage applied to these products must be
within their rated voltage range.
• Conductor size (AWG), length and ampacity
should be taken into consideration prior to design
and installation of these products, particularly in
retrofit installations.
4. Fenwal notification products must be used within the
published specifications and must be PROPERLY
specified, applied, installed, operated, maintained
and operationally tested in accordance with their
installation instructions at the time of installation and
at least twice a year or more often and in accordance with local, state and federal codes, regulations and laws. Specification, application ,
installation, operation, maintenance and testing
must be performed by qualified personnel for proper
