GROUNDING: Connect ground wire to backbox. Install signaling appliance to backbox using mounting screws provided.
WARNING: Verify the electrical ratings specified in Tables 1 and 2 (as appropriate) to ensure proper input. Ensure the speaker wir-
ing is connected to speaker terminals only and strobe wiring is connected to strobe terminals only. Ensure the wiring at FACP is
correct. Improper electrical input can damage the product or cause it to malfunction, which could result in property damage and
serious injury or death to you and/or others.

Each doubling of rated watts increases sound output by 3 dBA. Field selectable input terminals are provided on each unit. The follow-
ing wattage selections are available: 1/8W, 1/4W, 1/2W, 1W and 2W.

Each letter corresponds to a plug position of the header located on the printed circuit board. Select voltage and wattage as shown in
Table 4 below.

A 1.5
µ
F blocking capacitor for DC supervision of audio lines by the FACP is factory wired in series with the speaker input.
NOTE
: Use needlenose pliers to pull and properly insert the jumper plug to the desired tap setting.
WARNING: The speaker strobe appliance must be field set to the desired dBA sound output level before it is installed. This is done
by properly inserting jumper plugs in accordance with these instructions. Incorrect settings will result in improper performance,
which could result in property damage and serious injury or death to you and/or others.

NOTE:
The E70-24MCW comes pre-set at 15cd.
WARNING: The candela select switch must be field set to the required candela intensity before installation. When changing the
setting of the candela select switch, make certain that it clicks in place. After changing the candela setting, the appliance must be
retested to verify proper operation. Improper setting of the candela select switch, may result in operation at the wrong candela,
which could result in a current draw exceeding the power supply’s capacity.
MOUNTING PROCEDURES
1. The E70-24MCW can be flush mounted to a 4-inch square by 2-1/8-inch deep backbox with a 4-inch square 1-1/2-inch extension
ring (Figure A) or surface mounted to a surface backbox (Figure B). Mounting hardware for each mounting option is supplied.
2. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product. 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.
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. E70-24MCW model has an integrated speaker mounting plate which 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.
6. To move selector switch, insert screwdriver into slot shown on the bottom side of the strobe. The setting is indicated by a pointer and
can be seen on the bottom side of the lens. See Figure 5.
7. Mount the speaker mounting plate to the backbox. Next slide the grille over the speaker mounting plate strobe and attach with (2) screws.
WARNING: The speaker strobe appliance is a fire alarm device - DO NOT PAINT.
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, regard-
less of the viewer’s orientation. Failure to do so could result in property damage and serious injury or death to you and/or others.
The 110 candela strobe setting is Listed for use in sleeping or non-sleeping areas when installed in accordance with appropriate NFPA
Standards and the Authority Having Jurisdiction.
WARNING: Installation of Cooper Notification 110 candela strobe products in sleeping areas should be wall mounted at least 24
inches below the ceiling as follows: (1) the on-axis (directly in front of lens) light output should be directed at the eye-lids of the
sleeping person, e.g., Pillow end of bed, head of bed; (2) no part of the bed shall be more than sixteen (16) feet from the strobe
notification appliance. Installers must advise owners and operators of buildings with sleeping occupants, e.g., Hotels and motels,
to warn guests, residents and employees to not move the bed location to a position violating points (1) and (2) above or serious
injury and/or loss of life may occur during a fire emergency.
If this appliance is required to produce a distinctive three-pulse Temporal Pattern Fire Alarm Evacuation Signal (for total evacuation) in
accordance with NFPA 72, the appliance must be used with a fire alarm control unit that can generate the temporal pattern signal. Refer to
manufacturer’s installation manual for details.
NOTE:
NFPA 72/ANSI 117.1 conform to ADAAG Equivalent Facilitation Guidelines in using fewer, higher intensity strobes within the same
protected area.
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, Cooper Notification 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.
Cooper Notification 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.
CAUTION:
Verify 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).
