WARNING: MAKE SURE THAT THE TOTAL AVERAGE CURRENT AND TOTAL PEAK REQUIRED BY ALL APPLIANCES
THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES, NAC CIRCUITS, SM, DSM SYNC
MODULES AND PS-12/24-8 POWER SUPPLY 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 average or peak currents: Use Table 3 and 3A to determine the highest value of “Rated Average Current”
for an individual strobe (across the expected operating voltage range of the strobe), or use Table 3 to determine the highest value of
“Rated Peak Current” (whichever is higher) of an individual strobe (across the expected voltage range of the strobe), then multiply the
value by the total number of strobes; be sure to add the currents for any other appliances, including audible signaling appliances,
powered by the same source and include any required safety factors.
If the peak current exceeds the power supplies’ inrush capacity, the output voltage provided by the power supplies may drop below the
listed voltage range of the appliances connected to the supply and the voltage may not recover in some types of power supplies. For
example, an auxiliary power supply that lacks filtering at its output stage (either via lack of capacitance and/or lack of battery backup
across the output) may exhibit this characteristic.
CAUTION
: Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.

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.
1. The NS4-MCW model has an integrated NS Mounting Plate (NSMP).
2. The NS Mounting Plate (NSMP) must be oriented correctly when it is mounted to the backbox. Turn the NSMP so that the
arrow below the word “Top” points to the top side of the NSMP.
3. The NS4-MCW model can be flush mounted to a standard single-gang backbox (Figure A), 4” or 100mm backbox (Figure B) or
double-gang backbox (Figure C). The NS4-MCW can also be surface mounted to a 4” or 100mm backbox (Figure B), doublegang backbox (Figure C) or the SHBB (Figure D).
4. Mount the NSMP first to the backbox. Next slide the Beauty Plate over the NSMP until the 2 side snaps of the NS Beauty Plate
engage with the NSMP.
5. The NS Beauty Plate can be removed from the strobe assembly once engaged. First, gently insert a screwdriver into one of the
slots located on the side edges of the NS Beauty Plate. Second, gently pull away from the wall with the inserted screwdriver to
disengage the snap. Third, repeat the first and second steps for the second slot. Finally, gently lift the Beauty Plate away from
the NSMP.
6. Mounting hardware for each mounting option is supplied.
7. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product.
8. 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.
9. 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.
10. Do not pass additional wires (used for other than the signaling appliances) through the backbox. Such additional wires could
result in insufficient wiring space for the signaling appliance.
11. The effect of shipping and storage temperatures shall not adversely affect the performance of the appliance when stored in
original cartons and are not subjected to misuse or abuse. The NS4-MCW strobe is listed for indoor use.
WARNING: WHEN INSTALLING STROBES IN AN OPEN OFFICE OR OTHER AREAS CONTAINING
PARTITIONS OR OTHER VIEWING OBSTRUCTIONS, SPECIAL ATTENTION SHOULD BE GIVEN TO THE
LOCATION OF THE STROBES SO THAT THEIR OPERATING EFFECT CAN BE SEEN BY ALL INTENDED
VIEWERS, WITH THE INTENSITY, NUMBER, AND TYPE OF STROBES BEING SUFFICIENT TO MAKE SURE
THAT THE INTENDED VIEWER IS ALERTED BY PROPER ILLUMINATION, REGARDLESS OF THE VIEWER'S
ORIENTATION. FAILURE TO DO SO COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR
DEATH TO YOU AND/OR OTHERS.

CAUTION: If these appliances are operated within 15 inches of a person's ear, they can produce a sound pressure level that
exceeds the maximum 120dBA permitted by ADA and OSHA rules. Exposure to such sound levels can result in damage to a person's
hearing.
The 110 candela strobe model is Listed for use in sleeping or non-sleeping areas when installed in accordance with appropriate NFPA
Standards and the Authority Having Jurisdiction.
WARNING: INSTALLATION OF WHEELOCK 110 CANDELA STROBE PRODUCTS IN SLEEPING AREAS
SHOULD BE WALL MOUNTED AT LEAST 24" BELOW THE CEILING AS FOLLOWS: (1) THE ON AXIS
(DIRECTLY IN FRONT OF LENS) LIGHT OUTPUT SHOULD BE DIRECTED AT THE EYE-LIDS OF THE SLEEPING
PERSON, E.G. PILLOW END OF BED, BED HEAD; (2) NO PART OF THE BED SHALL BE MORE THAN SIXTEEN (16)
FEET FROM THE STROBE NOTIFICATION APPLIANCE. INSTALLERS MUST ADVISE OWNERS AND
OPERATORS OF BUILDINGS WITH SLEEPING OCCUPANTS, E.G. HOTELS AND MOTELS, TO WARN GUESTS,
RESIDENTS AND EMPLOYEES TO NOT MOVE THE BED LOCATION TO A POSITION VIOLATING POINTS (1)
AND (2) ABOVE OR SERIOUS INJURY AND/OR LOSS OF LIFE MAY OCCUR DURING A FIRE EMERGENCY.
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. 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.
These appliances can produce a distinctive three pulse Temporal Pattern Fire Alarm Evacuation Signal (for total evacuation) in
accordance with NFPA 72, 1999 Edition.
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).
