INSTALLATION INSTRUCTIONS

STROBE APPLIANCES

Use this product according to this instruction manual. Please keep this instruction manual for future reference.

GENERAL:

The Strobe Appliances are UL Listed under Standard 1638 for outdoor Fire Protective Service. They are listed for outdoor use, wall

mount, with the backboxes specified in these instructions (See Mounting Option). The Strobe Appliances use a Xenon flashtube with

solid state circuitry enclosed in a rugged Lexanlens to provide maximum visibility and reliability for effective visible signaling. All

inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring by a Fire Alarm Control Panel

(FACP).

NOTE: All CAUTIONS and WARNINGS are identified by the symbol . All warnings are printed in bold capital letters.

WARNING: READ THESE INSTRUCTIONS CAREFULLY. FAILURE TO COMPLY WITH ANY OF THE

FOLLOWING INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION,

INSTALLATION AND/OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD

RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

WARNING: THE STROBE APPLIANCES ARE NOT TO BE USED AS AN INDOOR VISUAL EVACUATION

SIGNAL OR FOR THE HEARING IMPAIRED.

2W in models number indicates white or clear lens. Substitute R for optional red lens (does not apply to WM models). Derate

intensity by 60% for red lens.

WARNING: ALTHOUGH UL TESTING HAS VERIFIED THAT THESE STROBES FUNCTION EVEN AT 80% OF

THEIR MINIMUM RATING AND 110% OF THEIR MAXIMUM RATING, WHEELOCK STRONGLY RECOMMENDS

THAT THE VOLTAGE APPLIED TO THESE PRODUCTS BE WITHIN THEIR RATED INPUT VOLTAGE RANGE.

THE APPLICATION OF IMPROPER VOLTAGE MAY RESULT IN DEGRADED OPERATION OR DAMAGE TO

THESE PRODUCTS, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO

YOU AND/OR OTHERS.

The UL Listed "Rated Input Voltage Range" is 18.0-31.0VDC for WHT-24, WH1T-24, WH3T-24, WM3T-24 and 12VDC for WHT-

12, WHIT-12, WH3T-12 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 strobes.

P82774 C

Sheet 2 of 5

Figure 1.

(For full-wave-rectified input voltage,

multiply 1.41 by percent value shown in

Figure 1.)

WARNING: MAKE SURE THAT THE TOTAL AVERAGE CURRENT REQUIRED BY ALL APPLIANCES THAT

ARE CONNECTED TO THE SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES AND APPLIANCE

CIRCUITS 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 value of "Rated Average Current" for an individual strobe then

multiply this value by the total number of strobes; be sure to add the current for any other appliances, including audible signaling

appliances, 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.

When calculating the maximum inrush or peak current: use Figure 1 to determine the highest value of "Rated Inrush Current" for a

strobe (across the expected operating voltage range of the strobe); then multiply that value by the total number of strobes on the

circuit; be sure to add the inrush or peak currents from any other appliances, including audible signaling appliances, on that circuit

and include any required safety factors. The time duration of the maximum strobe inrush is shown in Figure 1.

CAUTION: Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.

WIRING INFORMATION:

Figure 2. Figure 3.

1. Strobe Appliances have in-out wiring terminals that accepts 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 3. The polarity shown

in the wiring diagrams is for the operation of the appliances. The polarity is reversed by the FACP during supervision.

GROUNDING: Connect ground wire to backbox. Install the lockwasher (provided in hardware bag) under head of each mounting

screw and mount strobe appliance to backbox.

MOUNTING OPTIONS:

CAUTION: The following figure shows the maximum number of field wires (conductors) that can enter the backbox used with

this 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.

P82774 C

Sheet 4 of 5

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.

1. Mounting hardware for each mounting option is supplied.

2. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product.

3. 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.

4. 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.

5. 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.

6. All models are UL Listed for outoor use with a temperature range of +31°F to +150°F (-35°C to +66°C) and maximum

humidity of 95% RH.

WARNING: A SMALL POSSIBILITY EXISTS THAT THE USE OF MULTIPLE STROBES WITHIN A PERSON'S

FIELD OF VIEW, UNDER CERTAIN CIRCUMSTANCES, MIGHT INDUCE A PHOTO-SENSITIVE RESPONSE IN

PERSONS WITH EPILEPSY. STROBE REFLECTIONS IN A GLASS OR MIRRORED SURFACE MIGHT ALSO

INDUCE SUCH A RESPONSE. TO MINIMIZE THIS POSSIBLE HAZARD, WHEELOCK STRONGLY RECOMMENDS

THAT THE STROBES INSTALLED SHOULD NOT PRESENT A COMPOSITE FLASH RATE IN THE FIELD OF VIEW

WHICH EXCEEDS FIVE (5) Hz AT THE OPERATING VOLTAGE OF THE STROBES (SEE TABLE 2 AND 3).

WHEELOCK ALSO STRONGLY RECOMMENDS THAT THE INTENSITY AND COMPOSITE FLASH RATE OF

INSTALLED STROBES COMPLY WITH LEVELS ESTABLISHED BY APPLICABLE LAWS, STANDARDS,

REGULATIONS, CODES AND GUIDELINES.

NOTE: NFPA 72/ANSI 117.1 conform to ADAAG Equivalent Facilitation Guidelines in using fewer, higher intensity strobes within

the same protected area.

CAUTION: Check the installation instructions of the manufacturers of other equipment used in the system for any guidelines or

restrictions on wiring and/or locating Notification Appliance Circuits (NAC) and notification appliances. Some system

communication circuits and/or audio circuits, for example, may require special precautions to assure electrical noise immunity (e.g.

audio crosstalk).

ANY MATERIAL EXTRAPOLATED FROM THIS DOCUMENT OR FROM WHEELOCK MANUALS OR OTHER
