WIRING INFORMATION:
NOTE:
The Series MAX Strobe is not designed to operate on a synchronized circuit.
1. Jumper desired speakers together in parallel on the terminal block (Figure 5) using the same gauge wire as input. (Refer to
Figure 2, 3 and 4 for proper model numbering sequence.)
2.
Attach the speaker input wire to the proper terminals on the terminal block.
3.
Attach the 24VDC strobe input wires to the ± 24VDC terminals on the terminal block.
NOTE
: Strobe connections do not apply to the STH-2R, STH-3R or STH-4R models.

STROBE CONNECTION
ASSEMBLY:
1. Connect
±
24VDC pre-wires from the terminal block to the strobe pre-wires on the enclosure box cover plate using the wire-
nuts (provided). (Red to red. Black to black.)
2.
Replace enclosure box cover to the enclosure box and tighten the 4 Phillips Screws.
3.
Adjust the angle for the speakers to point in the directions desired.
CAUTION:
Always operate audio amplifiers and speakers within their specified ratings. Excessive input may distort sound
quality and may damage audio equipment. Do not 130% of speaker input voltage per UL 1480. Improper input voltage can
damage speaker. If distortion is heard, check for clipping of the audio appliance with an oscilloscope and reduce the amplifier input
level or gain level to eliminate any clipping.
NOTE:
NFPA 72/ANSI 117.1 conform to ADAAG Equivalent Facilitation Guidelines in using fewer, higher intensity strobes
within the same protected area.
