WARNING: OPERATING THE SERIES MIZ-TC12 UL VERSION, SET ON “CODE 3 TONE”
dBA AT MINIMUM VOLTAGE (8.0VDC) WILL NOT MEET THE 75 dBA MINIMUM UL
REVERBERANT SOUND LEVEL REQUIRED FOR PUBLIC MODE FIRE PROTECTION SERVICE
(NOTED BY * IN TABLE 1). MODELS WITH SETTINGS THAT PRODUCE LESS THAN 75 dBA
MAY NOT BE HEARD. THIS SETTING IS ACCEPTABLE ONLY FOR GENERAL SIGNALING (NON-
FIRE ALARM) USE.
WARNING: OPERATING THE MIZ-TC12 AND MIZ-TC24 AT MINIMUM VOLTAGE (8.0VDC
FOR 12 VOLT MODEL AND 16.0 FOR 24VDC MODEL) WILL NOT MEET THE 85 dBA MINIMUM
ULC ANECHOIC SOUND LEVEL REQUIRED FOR FIRE PROTECTION SERVICE (NOTED BY IN
TABLE 1). MODELS WITH SETTINGS THAT PRODUCE LESS THAN 85 dBA MAY NOT BE HEARD.
THIS SETTING IS ACCEPTABLE ONLY FOR GENERAL SIGNALING (NON-FIRE ALARM) USE.
The UL Listed “Regulated Voltage” range is shown in Table 1 using either
filtered (DC) or unfiltered full-wave-rectified (FWR) voltage. 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 signaling appliance.
NOTE:**
- Anechoic dBA is measured in anechoic chamber with peak meter response.
- Reverberant dBA is rated per UL standard 464.
- As per ULC requirement, the -3dB off-axis is 15° and the -6dB off-axis is 30°.

WARNING: MAKE SURE THAT THE TOTAL CURRENT REQUIRED BY ALL APPLIANCES THAT
ARE CONNECTED TO THE SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES AND
SIGNALING CIRCUITS DOES NOT EXCEED THEIR RATED CURRENT. OVERLOADING THESE
SOURCES 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.
CAUTION: This product is not designed to be used with the SM or DSM Sync
Modules.
WIRING INFORMATION
- 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.
- Break all in-out wire runs on supervised circuits to assure integrity of circuit supervision shown in Figure 2. The polarity shown in the wiring diagrams is for the operation of the appliances. The polarity is reversed by the FACP during supervision.
NOTE: Code 3 (shorted) Continuous (open)
Unit is shipped from factory with Code 3 selected (jumper to right). Installer
can select continuous audible signal by moving the factory installed jumper to
the left one position. The jumper will be placed only on the left pin, leaving
the circuit open to select Continuous.
MOUNTING OPTIONS
CAUTION: The following figures show the maximum number of field wires
(conductors) that can enter the backbox used with each mounting option. If
these limits are exceeded, there may be insufficient space in the backbox to
accommodate the field wires and stresses from the wires could damage the
product.
Although the limits shown for each mounting option comply with the National
Electrical Code (NEC), Wheelock recommends use of the largest backbox option
shown and the use of approved stranded field wires, whenever possible, to
provide additional wiring room for easy installation and minimum stress on the
product from wiring.
MOUNTING PROCEDURES
CAUTION: Check that the installed product will have sufficient clearance and
wiring room prior to installing backboxes and
conduit, especially if sheathed multiconductor cable or 3/4″ conduit fittings
are used.
- Mounting hardware for each mounting option is supplied.
- Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product. When extension rings are required, conduit should enter through the backbox, not the extension ring. Use Steel City #53151 (1-1/2″ deep) or #53171 (2-1/8″ deep) extension rings (as noted in the mounting options) or equal with the same cut-out area.
- When terminating field wires, do not use more lead length than required. Excess lead length could result in insufficient wiring space for the signaling appliance.
- Use care and proper techniques to position the field wires in the backbox so that they use minimum space and produce minimum stress on the product. This is especially important for stiff, heavy gauge wires and wires with thick insulation or sheathing.
- Do not pass additional wires (used for other than the signaling appliance) through the backbox. Such additional wires could result in insufficient wiring space for the signaling appliance.
- For Fire Alarm applications using white MIZ-Mini Horns, a red “Fire” Label is provided. Affix this label to the front of the mounting plate to identify the function of the alarm appliance.
- All models are UL 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.
