GENERAL DESCRIPTION
Chimes and chime/strobes are private mode notification appliances used to
alert trained personnel to investigate possible emergency situations and take
appropriate action. SpectrAlert Advance chimes and chime/strobes are electrically backward compatible with the previous generation of notification appliances. While they are specifically designed for use on the wall, the products
are listed to be used on the wall or ceiling. SpectrAlert products are designed
to be used in either 12 or 24 volt DC or full wave rectified (FWR) systems. If
required, the MDL3 module may be used in order to provide synchronization.
NOTICE: This manual shall be left with the owner/user of this equipment.
FIRE ALARM SYSTEM CONSIDERATIONS
The National Fire Alarm Code, NFPA 72, requires that all horns, used for
building evacuation installed after July 1, 1996, produce temporal coded signals. Signals other than those used for evacuation purposes do not have to
produce the temporal coded signal.
POWER SUPPLY CONSIDERATIONS
Panels typically supply DC filtered voltage or FWR (full wave rectified) voltage. The system design engineer must calculate the number of units used on
a loop based on the type of panel supply. Be certain the sum of all the device
currents does not exceed the current capability of the panel. Calculations are
based on using the device current found in the subsequent charts and must
be compatible with the current specified for the panel or power supply used.
NOTE: SpectrAlert chimes and chime/strobes must be powered from a noncoded power supply.
WIRE SIZES
The designer must be sure that the last device on the circuit has sufficient
voltage to operate the device within its rated voltage. When calculating the
voltage available to the last device, it is necessary to consider the voltage drop
due to the resistance of the wire. The thicker the wire, the smaller the voltage drop. Generally, for purposes of determining the wire size necessary for
the system, it is best to consider all of the devices as “lumped” on the end of
the supply circuit to simulate worst case. For the most accurate voltage drop
calculations use the System Sensor voltage drop calculator available on the
web or CD-ROM.
APPROXIMATE WIRE RESISTANCE:
18 AWG solid: 8 ohms/1000 ft.
16 AWG solid: 5 ohms/1000 ft.
14 AWG solid: 3 ohms/1000 ft.
12 AWG solid: 2 ohms/1000 ft.
NOTE: If Class A wiring is installed, the wire length may be up to twice as
long as on non-fault tolerant circuits.
CANDELA SELECTION FOR CHS SERIES MODELS
For strobe candela selection, adjust the slide switch located on the rear of
the product while watching the viewing window under the reflector on the
front of the unit. Use Table 1 to determine current draw at various candela
and chime tone settings. Tables 2 and 3 can be used to determine strobe light
output at various viewing angles.
NOTE: SpectrAlert products set at 15 and 15/75 candela automatically work
on either 12V or 24V power supplies. The products are not listed for 12V operating voltages when set to any other candela settings.

1. Attach mounting plate to junction box. The mounting plate is compatible
with 4˝ square, single gang, double gang, and 4˝ octagon junction boxes.
If using a back box skirt, attach the mounting plate to the skirt and then
attach the entire assembly to the junction box.
2. Connect field wiring according to terminal definitions.
3. If the product is not to be installed at this point, use the dust cover to
prevent contamination of the wiring terminals of the mounting plate.
4. To attach product to mounting plate, hook tabs on the product housing
into the grooves on mounting plate. Then, swing product into position to
engage the pins on the product with the terminals on the mounting plate.
Make sure that the tabs on the back of the product housing fully engage
with the mounting plate.
5. Secure product by tightening the single mounting screw in the front of
the product housing.

Please refer to insert for the Limitations of Fire Alarm Systems
WARNING
THE LIMITATIONS OF HORN/STROBES
The horn and/or strobe will not work without power. The horn/strobe gets its power
from the fire/security panel monitoring the alarm system. If power is cut off for any
reason, the horn/strobe will not provide the desired audio or visual warning. The horn
may not be heard. The loudness of the horn meets (or exceeds) current Underwriters
Laboratories’ standards. However, the horn may not alert a sound sleeper or one who
has recently used drugs or has been drinking alcoholic beverages. The horn may not be
heard if it is placed on a different floor from the person in hazard or if placed too far
away to be heard over the ambient noise such as traffic, air conditioners, machinery or
music appliances that may prevent alert persons from hearing the alarm. The horn may
not be heard by persons who are hearing impaired.
NOTE: Strobes must be powered continuously for horn operation.
THREE-YEAR LIMITED WARRANTY
System Sensor warrants its enclosed product to be free from defects in materials and
workmanship under normal use and service for a period of three years from date of
manufacture. System Sensor makes no other express warranty for this product. No agent,
representative, dealer, or employee of the Company has the authority to increase or alter
the obligations or limitations of this Warranty. The Company’s obligation of this Warranty
shall be limited to the replacement of any part of the product which is found to be defective in materials or workmanship under normal use and service during the three year
period commencing with the date of manufacture. After phoning System Sensor’s toll
free number 800-SENSOR2 (736-7672) for a Return Authorization number, send defective units postage prepaid to: System Sensor, Returns Department, RA #__________, 3825
The signal strobe may not be seen. The electronic visual warning signal uses an extremely reliable xenon flash tube. It flashes at least once every second. The strobe must
not be installed in direct sunlight or areas of high light intensity (over 60 foot candles)
where the visual flash might be disregarded or not seen. The strobe may not be seen
by the visually impaired. The signal strobe may cause seizures. Individuals who have
positive photoic response to visual stimuli with seizures, such as persons with epilepsy,
should avoid prolonged exposure to environments in which strobe signals, including this
strobe, are activated. The signal strobe cannot operate from coded power supplies. Coded
power supplies produce interrupted power. The strobe must have an uninterrupted
source of power in order to operate correctly. System Sensor recommends that the horn
and signal strobe always be used in combination so that the risks from any of the above
limitations are minimized.
Ohio Avenue, St. Charles, IL 60174. Please include a note describing the malfunction and
suspected cause of failure. The Company shall not be obligated to replace units which
are found to be defective because of damage, unreasonable use, modifications, or alterations occurring after the date of manufacture. In no case shall the Company be liable
for any consequential or incidental damages for breach of this or any other Warranty,
expressed or implied whatsoever, even if the loss or damage is caused by the Company’s
negligence or fault. Some states do not allow the exclusion or limitation of incidental or
consequential damages, so the above limitation or exclusion may not apply to you. This
Warranty gives you specific legal rights, and you may also have other rights which vary
from state to state.
SpectrAlert Strobes and Horn/Strobes have been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and
