General
The SpectrAlert® Advance series of mini-horn sounders are
designed to simplify installation to provide primary and sec-
ondary signaling for fire and security applications.
The MHR and MHW mini-horns are ideal for residential, hotel
or motel fire system applications, where a smaller notification
device is desired. The mini-horns come in versions that offer
high and low volume settings, temporal or non-temporal tones,
synchronization and silencing to meet the intent of the
National Building Code Section 3.2.4.18.9. The mini-horns can
be mounted to single-gang backboxes for aesthetically sensi-
tive applications. Synchronization is provided on certain mod-
els when using the MDLA module. Mini-horns with silencing
have an accelerated silence test feature which allows testing
of the silence operation without waiting for the entire time-out
period.
The MHR and MHW mini-horns can operate between 0°C to
49°C (32°F to 120°F) from a regulated DC or full-wave recti-
fied, unfiltered power supply.
Features
• 12 and 24V operation.
• High and low volume settings.
• Temporal and non-temporal tones.
• Mounts to a single-gang backbox.
• Low current draw.
• Accelerated silence test feature on silenceable models.
• Mechanically and electrically compatible with PA400 series
Mini-Alert™ sounders.

Specifications
MHRZA/MHWZA
Mini-horns shall be a System Sensor Model MHRZA or
MHWZA capable of operating at nominal 12 or 24 VDC and
shall mount to a single-gang backbox. Mini-horn shall be listed
to Underwriter’s Laboratories of Canada CAN/ULC S525. Mini-
horns shall operate between 0 and 49 degrees Celsius (32
and 120 degrees Fahrenheit) from a regulated DC, or full-wave
rectified, unfiltered power supply. When used with the
Sync•Circuit™ Module Model MDLA, 12-volt rated notification
appliance circuit outputs shall operate between 9 and 17.5
volts; 24-volt rated notification appliance circuit outputs shall
operate between 16 and 33 volts. Mini-horns shall have set-
tings for Hi/Low volume and temporal/continuous tones. A
silence feature shall be included to allow silencing of the mini-
horn to meet the intent of the National Building Code Section
3.2.4.18.9. Mini-horns shall have the ability of an accelerated
silence test feature and shall be able to operate from either
continuous or coded NAC circuits.
MHRA/MHWA
Mini-horns shall be a System Sensor Model MHRA or MHWA
capable of operating at nominal 12 or 24VDC and shall mount
to a single-gang backbox. Mini-horn shall be listed to Under-
writer’s Laboratories of Canada CAN/ULC S525. Mini-horns
shall operate between 0 and 40 degrees Celsius (32 and 120
degrees Fahrenheit) from a regulated DC, or full-wave recti-
fied, unfiltered power supply. When used with a Sync•Circuit
Module Model MDLA, 12-volt rated notification appliance cir-
cuit outputs shall operate between 9 and 17.5 volts; 24-volt
rated notification appliance circuit outputs shall operate
between 16 and 33 volts. Mini-horns shall have settings for Hi/
Low volume and temporal/continuous tones. Mini-horns shall
be able to operate from either continuous or coded NAC cir-
cuits.
MHR1A/MHW1A
Mini-horns shall be a System Sensor Model MHR1A or
MHW1A capable of operating at nominal 12 or 24VDC and
shall be mounted to a single-gang backbox. Mini-horn shall be
listed to Underwriter’s Laboratories of Canada CAN/ULC
S525. Mini-horns shall operate between 0 and 49 degrees
Celsius (32 and 120 degrees Fahrenheit) from a regulated DC,
or full-wave rectified, unfiltered power supply. Mini-horns shall
be able to operate from either continuous or coded NAC cir-
cuits.
