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. Mounting hard ware for each mounting option is supplied. The two unused mounting holes on the speaker grille can be filled
using short screws and retaining nuts (provided in hardware bag) prior to mounting appliance to backbox.
2. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product. When
extension rings are required, conduit should enter through the backbox, not the extension ring. Use Steel City #53151 (1-1/2"
deep) or #53171 (2-1/8" deep) extension rings (as noted in the mounting options) or equal with the same cut-out area.
3. 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.
4. 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.
5. 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.
6. ET-1010 speakers (without strobe) are UL listed for indoor/outdoor use with a temperature range of -31oF to 150oF (-35oC to
66oC) and maximum humidity of 95% RH. For weather resistant installation use Mounting Option F. Outdoor backbox must be
mounted vertically with "TOP" as marked to allow any moisture or condensation to drain properly through drain holes on bottom
of backbox. Use threaded conduit entrance to insure water tightness. Do not use knockout entrance. All other models are UL
Listed for indoor use with a temperature range of 32oF to 120oF (0oC to 49oC) and maximum humidity of 85% RH.
7. Each doubling of rated Watts increases sound output by 3 dBA. Field selectable input terminals are provided on each unit. The
following wattage selections are available: 1/8W, 1/4W, 1/2W, 1W, 2W, 4W, and 8W. Frequency range of speakers is 400-
4000Hz.
8. A 10
µ
F blocking capacitor for DC supervision of audio lines by the FACP is factory wired in series with the speaker input.
CAUTION
:
Always operate audio amp lifiers 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.
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.
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 (SEE TABLE 4). 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.
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).
ANY MATERIAL EXTRAPOLATED FROM THIS DOCUMENT OR FROM WHEELOCK MANUALS OR OTHER DOCUMENTS
DESCRIBING THE PRODUCT FOR USE IN PROMOTIONAL OR ADVERTISING CLAIMS, OR FOR ANY OTHER USE, INCLUDING
DESCRIPTION OF THE PRODUCT'S APPLICATION, OPERATION, INSTALLATION AND TESTING IS USED AT THE SOLE RISK
OF THE USER AND WHEELOCK WILL NOT HAVE ANY LIABILITY FOR SUCH USE.
