40 WATT EXPLOSION PROOF HORN

V-5331215A

INTRODUCTION

Explosion Proof Horn Speakers are constructed so

that all electrical components are sealed from the

atmosphere and may be used in areas where

flammable substances are present. The explosion

proof speakers require some assembly before

installation (See Figure 1).

Explosion proof speakers are mounted, using the

U-shaped mounting bracket (Attached to each

speaker). These brackets are intended primarily for

mounting on flat surfaces, and each bracket has three

holes which may be used for installing mounting

hardware. Speaker position in the vertical axis may be

adjusted by loosening the bolts that secure the

bracket to the speaker body (See Figure 1).

INSTALLATION

Mounting

Separate the horn and the base of the speaker by

holding the base of the speaker tightly and turning the

horn counterclockwise (See Figure 1, View 1).

Separate the two halves of the speaker base by

removing the eight bolts (See Figure 1, View 2).

Make the conduit entry into the speaker as required

by local ordinances for the class and type of speaker

used (See Figure 1, View 3).

On the speaker cable, separate the inner wires for a

distance of 3 or 4 inches by stripping away insulation

from the main cable. If using shielded cable, the inner

wire without insulation is the shield wire. Strip

approximately 1/2 inch of insulation from the end of

each of the smaller insulated wires.

Note: The cable must enter the speaker through a

conduit that has been installed according to local

ordinances for the class and type of speaker used.

Connect the wires on terminals 1 and 2. If shielded

cable is used, either splice the shield wire to provide a

continuous shield to the next speaker or clip the

shield wire at the point where it emerges from the

main cable, as appropriate. The shield wire should not

be terminated on the speaker.

POWER ADJUSTMENTS

If necessary, remove the power tap selection wire

(White wire) and reattach it to the desired power tap.

The numbers on the terminal strip indicate the output

in Watts for a 70Volt paging system (On a 25Volt

paging system, the output will be approximately 1/8 of

that indicated (See Table 1). Reassemble the two

halves of the speaker case by reinstalling the eight

bolts.
