SERIES ET70-24MCCH, ET90-24MCCH MULTI-HIGH-CANDELA SPEAKER STROBE
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
Cooper Notification’s Series ET70-24MCCH and ET90-24MCCH Multi-High-Candela Low Profile Speaker Strobe is UL Listed under Standard 1971 for
(Signaling Devices for the Hearing Impaired) for indoor fire protection service. Models with amber, red, blue or green lens are UL Listed under Standard
UL1638 (Visual Signaling Appliance) for Private Mode Emergency and General Utility Signaling. These speaker stobes are designed for multiple power
requirements with high dBA output at each power tap and offer a choice of field selectable taps, 1/8W to 8W for either 25.0VRMS or 70.0VRMS audio
systems. The low profile design incorporates a high efficiency speaker for maximum output at minimum power across a frequency range of 400Hz to
4000Hz, and features a sealed back construction for extra protection and improved audibility. The Multi-High-Candela models provide two selectable
light output intensities in one unit and incorporates a speaker mounting plate attached to the speaker for ease of installation. The Low Profile Speaker
Strobe can provide a non-synchronized strobe appliance when connected directly to a fire alarm control panel (FACP), or provide a synchronized strobe
appliance when used in conjunction with a Sync Module (SM), Dual Sync Module (DSM) or Cooper Notification power supplies. The strobe uses a
xenon flashtube with solid state circuitry enclosed in a polycarbonate
lens to provide maximum visibility and reliability for effective visible signaling.
These models are Listed for
indoor use, ceiling mount only
with the backboxes specified in these instructions (see wiring and mounting information).

NOTES:
1.
The strobe will produce 1 flash per second over the "Regulated Voltage" range.
2.
Strobes with clear and amber lens meet the required light distribution patterns defined in UL 1971.
3.
All models are UL Listed for indoor use with a temperature range of +32
F to +120
F (0
C to +49
C) and maximum humidity of 85% RH. The
effect of shipping and storage temperatures shall not adversely affect the performance of the appliance when it is stored in the original cartons and
is not subjected to misuse or abuse.
4.
The maximum supervision voltage is 33 volts DC.
5.
Frequency range of speakers is 400-4000Hz.
6.
Ratings listed in Table 1 are for clear lens. Derate approximately 25% for amber lens, 55% for green, 70% for blue and 80% for red.
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 100% 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: CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT.

When calculating the total currents use Table 2 to determine the highest value of RMS current for an individual strobe, then multiply these values by the
total number of strobes. Be sure to add the currents for any other appliances, including audible signaling appliances powered by the same source, and
to include any required safety factors.
NOTE:
The maximum number of strobes on a single notification appliance circuit shall not exceed 50.
CAUTION:
These strobes are UL Listed as “Regulated”. They are intended to be used with FACPs whose notification circuits are UL Listed as
“Regulated.” These appliances shall not be used on UL Listed “Special Application” notification circuits unless the appliances are identified to be
compatible in the installation instructions of the FACP or unless the FACP is identified to be compatible in this instruction manual.
WARNING: THESE STROBES WERE TESTED TO THE REGULATED VOLTAGE LIMITS OF 16.0-33.0 VOLTS FOR 24V MODELS USING
FILTERED DC OR UNFILTERED FULL-WAVE-RECTIFIED VOLTAGE. DO NOT APPLY VOLTAGE OUTSIDE OF THIS RANGE.
