S ound output levels are established at Underwriters
Laboratories in their anechoic room. Always use the
sound output specified as UL Anechoic Room when
comparing products.
Model SP2R1224MCK incorporates a new 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.
NOTICE: This manual shall be left with the owner/user of
this equipment.
General Description
The SpectrAlert SP2 series speaker/strobes are designed to
meet the requirements of most agencies governing these
devices, including: NFPA, ADA, The National Fire Alarm
Code, UL. Also, check with your local Authority Having
Jurisdiction for other codes or standards that may apply.
The SpectrAlert SP2 series speakers can be operated with
distribution amplifiers having an output voltage of either
25 volts or 70.7 volts.
The speakers operate at any one of four input power levels.
The output sound level is selected at the time of installa-
tion, but can be changed, if necessary.

12/24 Volt Applications:
24 Volt Application:
1 5/75 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.
Listings: UL 1971/1638 (Strobe); UL 1480 (Speaker); NEMA 3R
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
impedance of 4 ohms per loop and; 3) maximum line imped-
ance as required by the fire alarm control manufacturer.
The speaker is also equipped with a capacitive input to
allow for DC supervision.
The SpectrAlert SP2 series strobe can be installed in systems
using 12 or 24-volt panels having DC or full-wave rectified
(FWR) power supplies. The strobes can also be installed
in applications requiring synchronization (module MDL or
compatible equivalent required) or applications that do not
require synchronization (no module required).
Power Supply Considerations For Strobes
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 Table 2 and must be the current specified for the type of
panel power supply used.
