15 or 15/75 candela
30, 75, 110 candela
15/75 is listed at 15 candela per UL 1971 but will provide 75 candela on axis
(straight ahead). 15, 30, 75, or 110 are rated for that candela.
Sound output levels are established at Underwriters Laboratories in their reverber-
ant room. Always use the sound output specified as UL Reverberant Room when
comparing products.

Listings:
UL S5512 (Strobe); UL S4011 (Combo)
Note for Strobes:
Do not exceed: 1) 8-17.5 or 16-33 voltage range limit; 2) maximum number of 70
strobe lights when connecting the MDL Sync module with a maximum line im-
pedance of 4 ohms per loop and; 3) maximum line impedance as required by the
fire alarm control manufacturer.
The models S1224MC, S1224MCW, S1224MCSP, S1224MCSPW, S1224MCP, S1224MCPW, P1224MC, P1224MCW, P1224MCSP, P1224MCSPW, P1224MCP, and
P1224MCPW incorporate a patented voltage booster design that has a more consistent flash bulb voltage over the range of candela selections. The benefit to
the customer is a high quality strobe device.
General Description
stalled after July 1, 1996, must produce Temporal Coded Signals.
The SpectrAlert series notification appliances are designed to
Signals other than those used for evacuation purposes do not have
to produce the Temporal Coded Signal. Temporal coding is accom-
plished by interrupting a steady sound in the following manner:
meet the requirements of most agencies governing these devices,
including: NFPA, ADA, The National Fire Alarm Code, UL, ULC,
FM, CSFM, MEA. Also, check with your local Authority Having
Jurisdiction for other codes or standards that may apply.
The SpectrAlert series can be installed in systems using 12- or 24-
volt panels having DC or full-wave rectified (FWR) power supplies.
The series can also be installed in systems requiring synchroniza-
tion (module MDL or compatible equivalent required) or systems
that do not require synchronization (no module required).

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 in a zone based on the type of panel supply.
Be certain the sum of all the device currents do not exceed the
current capability of the panel. Calculations are based on using
the device current found in the subsequent charts and must be
the current specified for the type of panel power supply used.
NOTICE: This manual shall be left with the owner/user of this equipment.
Fire Alarm System Considerations
Temporal and Non-Temporal Coded Signals:

Alarm Code require that all horns used for building evacuation in-

Figure 2: Candela Selections
For strobe candela selection, adjust slide switch located
on the rear of the product while watching the viewing win-
dow on the side of the reflector.
NOTE: The strobe is not listed for 12V operating voltages when
set to 30, 75 or 110 candelas. Use only those settings marked as
OK in the chart above.

FCC Statement
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 com-
mercial environment. This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user will be required to correct the interference
at his own expense.
