Note 3: Measured at 10 feet in an anechoic chamber.
Note 4: Measured in a UL reverberant room.
Note 5: Only continuous tones (800Hz, 2400 Hz) can be temporally
coded per UL. Strobes cannot be used on an MDL module pro­viding temporal coding to Multi-Alert™ horns.
The sound selected determines the maximum current and sound power output per device. SeeTable 2 for these values.
Independent Sounder/Strobe Operation
There may be applications where it is desirable to drive the sounder and strobe as independent devices. The System Sensor MASS12/24ADA series sounder/strobes are easily configured for this capability. The terminal connection for this application is shown in Figure 6. Independent strobe operation in a coded system requires a separate uncoded power supply for the strobe.
Installation - For Strobe Placement, See NFPA 72, Chapter 6
A. General: Slotted head screws are used to attach each de-
vice or combination of devices to the electrical outlet box. Phillips head screws are used to attach accessories to the horn. Refer to Figures 3,4,5, and 6 for wiring methods.
B. Sounder/Strobe combination mounting:
1. Surface Mount: (See Fig. 10)
2. Semi Flush Mount: (See Fig. 11 and 14)
C. Sounder mounting:
1. Surface Mount : (See Fig. 7)
2. Semi Flush Mount: (See Fig. 11 and 14)
3. Flush Mount (See Fig. 13) Flush mounting requires the use of the deep box (Part # BB-D) or equivalent. Determine which of the two device holes will be used to attach the device to the box. Mount the flush plate to the sounder using the other two holes with two 1-inch phillips head screws and two square nuts.
D. Strobe mounting:
1. Surface Mount: (See Fig. 9)
2. Semi Flush Mount (See Fig.12)
Installation procedures must conform to all applicable codes and the requirements of the authority having jurisdiction.
NOTES: Do not loop wires under the terminal screw. Wires
connecting the device to the panel must be broken at the device terminal connection in order to maintain electrical supervision.
NOTE: The rated output of the sounder is specified at 10
feet. It cannot be assumed that the output will meet the NFPA standard of 15 dB over ambient noise at all locations within a room. Additional sounders may be needed to ensure sound output

signed for wall mounting ONLY.
The sounder is 1-1/4" deep. Back boxes must be 4" square by at least 1-1/2" deep – 2-1/8" deep box is rec­ommended.
All strobes must be mounted so that the top of the lens is 24 inches (61 cm) below ceilings or as required by the authority having jurisdiction.
WARNING
The Limitations of Sounder/Strobes
The Sounder and/or Strobe will not work without power. The sounder/ strobe gets its power from the fire/security panel monitoring the alarm system. If power is cut off for any reason, the sounder/strobe will not pro­vide the desired audio or visual warning.
The Sounder may not be heard. The loudness of the sounder meets (or exceeds) current Underwriters Laboratories’ standards. However, the sounder may not alert a sound sleeper or one who has recently used drugs or has been drinking alcoholic beverages. The Sounder 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 Sounder may not be heard by persons who are hearing impaired.
The Signal Strobe may not be seen. The electronic visual warning signal that flashes at least once every three seconds meets or exceeds current Un­derwriters Laboratories’ standard 1971 and uses an extremely reliable xe­non flash tube. The visual warning signal is suitable for direct viewing and must be installed within an area where it can be seen by building occu-
D900-06-00 2 I56-750-58
pants. 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 a positive photic response to visual stimuli with seizures, such as epileptics, should avoid prolonged exposure to environments in which strobe signals, in­cluding this strobe, are activated.
System Sensor recommends that the Multi-Alert Sounder and Signal Strobe always be used in combination so that the risks from any of the
above limitations are minimized.
The signal strobe cannot operate from coded power supplies. Coded power supplies produce interrupted power. The strobe must have an unin­terrupted source of dc power in order to operate correctly.
Synchronized strobes may not prevent photosensitive reactions to signal strobes in alarm condition.
