INSTALLATION INSTRUCTIONS
MIZ-MINI HORNS
Electronic MIZ-Mini Horns are designed to produce high sound output with minimal current requirements. They are UL Listed under
UL 464, Standard for Audible Signal Appliances and ULC Listed under Standard CAN/ULC-S525-99, Standard for Audible Signal
Appliances For Fire Alarm Systems. All inputs are polarized for compatibility with standard reverse polarity supervision of circuit
wiring by a Fire Alarm Control Panel (FACP). MIZ-Mini Horns are recommended for alarm signaling for individual rooms in
apartments, motels, hotels and offices. These appliances are attractive in appearance and reliable performers. They mount to standard
backboxes to reduce the cost of installation. All models are Listed for indoor use with the backboxes specified in these instructions
(See Mounting Options).
They provide a selectable Continuous or Code 3 horn tone when connected directly to a Fire Alarm Control Panel (FACP). They can
also provide a synchronized Code 3 horn tone when used in conjunction with a Sync Module (SM), Dual Sync Module (DSM) or
Wheelock’s Power Supplies.

WARNING: OPERATING THE SERIES MIZ-TC12 UL VERSION, AT MINIMUM VOLTAGE (8.0VDC TO 12.0VDC) WILL NOT
MEET THE 75dBA MINIMUM UL REVERBERANT SOUND LEVEL REQUIRED FOR PUBLIC MODE FIRE PROTECTION
SERVICE (NOTED BY * IN TABLE 1). THIS IS ACCEPTABLE ONLY FOR GENERAL SIGNALING (NON-FIRE ALARM) USE.
WARNING: OPERATING THE MIZ-TC12 AND MIZ-TC24 AT MINIMUM VOLTAGE (8.0VDC TO 12.0VDC FOR 12 VOLT
MODEL AND 16.0 FOR 24.0VDC MODEL) WILL NOT MEET THE 85dBA MINIMUM ULC ANECHOIC SOUND LEVEL REQUIRED
FOR FIRE PROTECTION SERVICE (NOTED BY ** IN TABLE 1). THIS IS ACCEPTABLE ONLY FOR GENERAL SIGNALING
(NON-FIRE ALARM) USE.
WARNING: FOR UL APPLICATIONS THESE APPLIANCES WERE TESTED TO THE OPERATING VOLTAGE LIMITS OF
16.0-33.0 VOLTS FOR 24.0VDC MODELS AND 8.0-17.5 VOLTS FOR 12.0VDC MODELS USING FILTERED (DC) OR UNFILTERED
FULL-WAVE-RECTIFIED (FWR). DO NOT APPLY 80% AND 110% OF THESE VOLTAGE VALUES FOR SYSTEM OPERATION.
WARNING: FOR ULC APPLICATIONS THESE APPLIANCES WERE TESTED TO THE OPERATING VOLTAGE LIMITS OF
20.0-31.0 VOLTS FOR 24VDC MODELS USING FILTERED (DC) OR UNFILTERED FULL-WAVE-RECTIFIED (FWR). APPLY 80%
AND 110% OF THESE VOLTAGE VALUES FOR SYSTEM OPERATION.
: 1. Anechoic dBA is measured in anechoic chamber with fast meter response. 2. Reverberant dBA is rated per UL 464,
NOTE
Standard for Audible Signal Appliances. 3. As per ULC requirement, the -3dB off-axis is 15° and the -6dB off-axis is 30°.

WARNING: CHECK THE MINIMUM AND MAXIMUM OUTPUT OF THE POWER SUPPLY AND STANDBY
BATTERY AND SUBTRACT THE VOLTAGE DROP FROM THE CIRCUIT WIRING RESISTANCE TO DETERMINE
THE APPLIED VOLTAGE TO THE STROBES.
WARNING: MAKE SURE THAT THE CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO
THE SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES, NAC CIRCUITS, SM, DSM SYNC MODULES OR
WHEELOCK’S POWER SUPPLIES DO NOT EXCEED THE POWER SOURCES’ RATED CAPACITY OR THE
CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO WHICH THESE APPLIANCES ARE WIRED.
OVERLOADING POWER SOURCES OR EXCEEDING FUSE RATINGS COULD RESULT IN LOSS OF POWER AND
FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY, WHICH COULD RESULT IN PROPERTY DAMAGE
AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
When calculating the total current: use Table 1 to determine the highest value of “Rated Average Current” for an individual horn
(across the expected operating voltage range of the device); then multiply this value by the total number of devices; be sure to add the
current for any other devices powered by the same source and include any required safety factors.
WARNING: MAKE SURE THAT ALL FUSES USED ON SIGNALING CIRCUITS ARE RATED TO HANDLE THE
MAXIMUM INRUSH OR PEAK CURRENT FROM ALL APPLIANCES ON THOSE CIRCUITS. FAILURE TO DO THIS
MAY RESULT IN LOSS OF POWER TO THE SIGNALING CIRCUIT AND THE FAILURE OF ALL APPLIANCES ON
THAT CIRCUIT TO OPERATE, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR
DEATH TO YOU AND/OR OTHERS.

1) Appliances have in-out wiring terminals that accept two #12 to #18 American Wire Gauge (AWG) wires at each screw terminal.
Strip leads 3/8 inches and connect to screw terminals.
2) Break all in-out wire runs on supervised circuits to assure integrity of circuit supervision shown in Figure 1. The polarity shown
in the wiring diagrams is for the operation of the appliances. The polarity is reversed by the FACP during supervision.
