SERIES MAX INDUSTRIAL STROBES

INSTALLATION INSTRUCTIONS

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

GENERAL:

Wheelock's Series Max Strobes are UL 1638 Listed for indoor or outdoor use. They are high intensity visible warning
appliances that are designed for use in either stationary locations or mobile equipment. All Series Max Strobes are weather­resistant. They produce a powerful double flash light burst at the rate of 60 double flashes per minute. Series Max Strobes can
be installed using 1/2-inch pipe mount, surface mount or flange mount (an integral 1/2-inch pipe thread, a flange mounting ring
and a weather-resistant gasket are included with each unit). They can also be mounted to standard 4-inch square electrical boxes,
100mm European boxes and Wheelock's WBB outdoor box. There are four models of Series Max Strobes: The AC-MAX and
AC-MAXS Models for 120VAC applications and the DC-MAX and DC-MAXS Models for use with any DC voltage from

10.5VDC to 31.0VDC. The AC-MAX and DC-MAX are strobe only models while the AC-MAXS and DC-MAXS models offer
a steady-light feature along with the strobe operation. All models are available with either clear, amber, red, or blue lens color.

NOTE

All wiring must comply with the NEC and all local electrical codes.

AC–MAX and AC-MAXS MODELS

Weight 2lbs.

: The Series MAX Strobe is not designed to operate on a synchronized circuit.

Base - high strength, high temperature G.E. Lexan 

Lens - high strength, high temperature G.E. Lexan 

The AC Industrial Strobes are designed to operate on 120VAC. Two #18 AWG leads are provided on both models for electrical
hook-up of the strobe circuit. Two #18 AWG leads are provided on the AC-MAXS model for electrical hook-up of the steady­lights. The AC power source should be suitably fused and #18 AWG minimum wire size is recommended.

When wiring the AC-MAXS models, the blue wires are for the steady light. The black wire and white wire are for the high
intensity strobe.

DC–MAX and DC-MAXS MODELS

The DC Industrial Strobes are designed to operate from 10.5VDC to 31.0VDC. Two #18 AWG leads are provided on both
models for electrical hook-up of the strobe circuit, red positive and black negative. The circuit is reverse polarity protected and
will not operate if connected improperly. A 10 Amp fuse and #18 AWG minimum wire size is recommended. Inrush current
draw at 12 volts is 5A max, 24 volts is 10A max, and 31 volts is 12A max. Two #18 AWG leads are provided on the DC-MAXS
model for electrical hook-up of the steady-lights. The steady-light connection is not polarity sensitive.

MOUNTING INFORMATION:

: The Series MAX Strobes are not intended for use in wash down areas.

NOTE

All mounting methods must comply with the NEC and all local electrical codes.
A. 1/2”

PIPE MOUNT

(See Figure A)

Use 1/2-inch NPT threaded conduit making sure there is an adequate length of wire to work with. Follow the wiring

procedures outlined in the wiring section. Use appropriate wiring box or conduit for high voltage applications as required
by electrical codes. Carefully thread strobe over conduit by hand until it is secure.

CAUTION

: Over tightening may result in damage to base.

B. 4" or 100mm BACKBOX (tamper resistant installation) (See Figure B)
Remove the three screws securing the strobe lens to the base and remove the lens. Using a screwdriver and hammer,

remove the appropriate plastic knockouts located in the strobe base. Use the mounting gasket supplied when mounting the
strobe to a recessed backbox over a flat surface when a water-resistant seal is required. Feed the lead wires through the
center hole of the mounting gasket and keep the gasket in place against the strobe base. If the strobe is to be mounted to a
weather-resistant backbox use the gasket supplied with the backbox. Make the wiring connections as outlined in the wiring
section. Neatly tuck the wiring connections into the backbox and position the strobe over the mounting surface. Use four
#8-32 x 1" screws, (customer supplied) to fasten the strobe to the backbox for weather-resistant applications, otherwise two
diagonally placed #8-32 x 1" screws, (customer supplied) will be adequate. Reassemble the strobe lens to the base taking
care to ensure that the sealing gasket is properly seated and the screws are uniformly tightened.

SURFACE MOUNT

C.

(See Figure C)

Remove the three screws securing the strobe lens to the base and remove the lens. Using a screwdriver and hammer,

remove the appropriate plastic knockouts located in the strobe base. Using the mounting gasket as a template, mark the
mounting surface for drilling. Drill one 3/8-inch wire access hole and either two or four appropriately sized mounting
holes, as the application requires. Remove all burrs from the wire access hole to prevent damage to the wires. Use the
mounting gasket supplied when mounting the strobe to a flat surface where a weather-resistant seal is required. For
weather-resistant applications it is recommended to use four mounting screws (customer supplied), otherwise two
diagonally placed screws, (customer supplied) will be adequate. Place the gasket on the mounting surface and feed the lead
wires through the center hole while positioning the strobe. Make the electrical connections as outlined in the wiring
section. Use appropriate wiring box for high voltage applications as required by electrical codes. Fasten the strobe base to
the mounting surface using the appropriate hardware. Reassemble the strobe lens to base taking care to ensure that the
sealing gasket is properly seated and the screws are uniformly tightened.

FLANGE MOUNT

D.

(See Figure D)

Position the strobe on the mounting surface with the lead wires exiting straight out from the center. Place the mounting

flange over the strobe and mark the locations of the three flange mounting screws. Drill three 1/4-inch pilot holes. Drill a
3/8-inch wire access hole in the center of the mounting hole pattern. Remove all burrs from the wire access hole to prevent
damage to the wires. For weather-resistant applications place the mounting gasket over the mounting surface. Feed the
lead wires through the access hole and mount the strobe using the mounting ring and the supplied hardware. Make the
wiring connections as outlined in the wiring section. Use appropriate wiring box for high voltage applications as required
by electrical codes.
