SERIES CH70/90 ELECTRONIC CHIMES AND CHIME STROBES
INSTALLATION INSTRUCTIONS
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
Wheelock’s Series CH70/90 Electronic Chimes and Chime Strobes are UL Listed under Standard 1971 for Signaling Devices for the
Hearing Impaired and UL Standard for Private Mode Audible Signal Appliances. CH70/90 Chimes are designed for low current draw
and versatile performance. All models offer a choice of single stroke or vibrating operation, have adjustable sound level to 83dBA
(peak anechoic) at 10 feet, and have a chime tone adjustable from 800 to 1200Hz. The Series CH70/90 appliances also incorporate a
Chime Mounting Plate attached to the chime for ease of installation. CH70 Chime Strobe models 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) or a Dual Sync Module (DSM). The strobes use a Xenon flashtube with solid state
circuitry enclosed in a rugged Lexan lens to provide maximum visibility and reliability for effective visible signaling. The
241575W candela wall mounted strobes are listed at 15 candela under UL Standard 1971 and meet 75 candela intensity on axis with
low current draw. The CH70 Chime Strobes for wall mounting only
2415W, 241575W, 2430W, 2475W and 24110W. The CH90 Chime Strobes for ceiling mounting only
are available with a choice of five UL Listed strobe options:
are available with a choice of
two UL Listed strobe options: 2475C and 24100C. The CH90 Chime is for wall or ceiling mounting. All models are Listed for
indoor use only

Table 1: UL Listed Models and Ratings
* 241575W models are UL Listed at 15cd and meet 75cd on axis.
Notes:
1. Models with strobe will produce 1 flash per second over the listed voltage range.
2. All models are UL Listed for indoor use with a temperature range of +32oF to +120oF (0oC to +49oC) and maximum humidity
of 85% RH.
3. Chimes must be set at maximum volume for Private Mode Fire Protective Service per UL 1638 listing requirements (see Wiring
Information Note 2).
4. Anechoic dBA is measured in an anechoic chamber with peak meter response. Reverberant dBA is rated per UL Standard 464.
5. The chimes produce a brief inrush current of 0.100 Amps with filtered DC input (0.140 Amps with full-wave-rectified (VRMS)
input) with a time duration of 100 milliseconds.
The UL Listed "Rated Input Voltage" is 20.0-31.0VDC using either filtered (DC) input or unfiltered full-wave-rectified (VRMS)
voltage.
Check the minimum and maximum output of the power supply and standby battery and subtract the voltage drop from the circuit
wiring resistance to determine the applied voltage to the strobes.

WARNING: ALTHOUGH UL TESTING HAS VERIFIED THAT THESE STROBES FUNCTION EVEN AT 80% OF THEIR
MINIMUM RATING AND 110% OF THEIR MAXIMUM RATING, WHEELOCK STRONGLY RECOMMENDS THAT THE
VOLTAGE APPLIED TO THESE PRODUCTS BE WITHIN THEIR RATED INPUT VOLTAGE RANGE. THE APPLICATION OF
IMPROPER VOLTAGE MAY RESULT IN DEGRADED OPERATION OR DAMAGE TO THESE PRODUCTS, WHICH COULD
RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

* Rated Average Current is measured using mean value.
** The time duration for the peak current is 100 microseconds.
*** The time duration for the inrush current is 4 milliseconds.
WARNING: MAKE SURE THAT THE TOTAL AVERAGE CURRENT, TOTAL PEAK CURRENT AND TOTAL INRUSH
CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY AND SECONDARY
POWER SOURCES, NAC CIRCUITS, SM AND DSM SYNC MODULES DO NOT EXCEED THE POWER SOURCES’ RATED
CAPACITY OR THE CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO WHICH THESE APPLIANCES ARE WIRED.
OVERLOADING POWER SOURCES OR EXCEEDING FUSE RATINGS COULD RESULT IN LOSS OF POWER AND FAILURE TO
ALERT OCCUPANTS DURING AN EMERGENCY, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR
DEATH TO YOU AND/OR OTHERS.
When calculating the total average, peak and inrush currents: Use Table 2 to determine the highest value of “Rated Average Current”
for an individual chime strobe (across the expected operating voltage range of the chime strobe), and the highest value of “Rated
Inrush Current” or “Rated Peak Current” (whichever is higher) of an individual chime strobe (across the expected voltage range of the
chime strobe), then multiply these values by the total number of chime strobes; be sure to add the currents for the chimes and any
other appliances, including audible signaling appliances, powered by the same source and include any required safety factors.
If the inrush current or peak current exceeds the power supplies’ inrush capacity, the output voltage provided by the power supplies
may drop below the listed voltage range of the appliances connected to the supply and the voltage may not recover in some types of
power supplies. For example, an auxiliary power supply that lacks filtering at its output stage (either via lack of capacitance and/or
lack of battery backup across the output) may exhibit this characteristic.
:
CAUTION
Chime Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.
