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. ET70/90 models have an integrated Speaker Mounting Plate.
2. The Speaker Mounting Plate must be oriented correctly when it is mounted to the backbox. Turn the Speaker Mounting Plate so
that the arrow above the words “Horizontal Strobe” points to the top side of the Speaker Mounting Plate.
3. First mount the Speaker Mounting Plate to the backbox with the Cone Protector on; after the Speaker Mounting Plate is attached
to the backbox, remove the Cone Protector before installing the grille. Next slide the grille over the Speaker Mounting Plate
strobe and attach with (2) screws.
4. 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.
5. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product.
6. 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.
7. Mounting hardware for each mounting option is supplied.
8. All models can be flush mounted to a 4” square by 1-1/2” deep backbox with a 4” square 1-1/2” extension ring (Figure A or B).
ET70 models can also be surface mounted to a SBB (Figure C or D).
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.
CAUTION: Always operate audio amplifiers and speakers within their specified ratings. Excessive input may distort sound
quality and may damage audio equipment. Do not exceed +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.
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.
ET70-24110W strobe models are Listed for use in sleeping or non-sleeping areas when installed in accordance with appropriate
NFPA Standards and the Authority Having Jurisdiction.
