Instruction Manual
GENERAL
The System Sensor SS24ADAS Series Synchronized Strobes are crystal-controlled to flash at precisely one flash per second. When power is applied to an indicating circuit controlled by one controller, all SS24ADAS or MASS24ADAS series devices in that zone will flash simultaneously. No synchronizing modules or coded supplies are necessary. The strobes can be used in any combination with other System Sensor ADA strobes, ADA horn/ strobes, and ADA speaker/strobes. The unique lens/reflector design maintains the UL 1971 light dispersement pattern while flashing at the ADA minimum 1 flash per second. Available in red at 24 VDC, the SS24ADAS strobes can be surface-mounted directly to a standard 4″ (101.6 mm) backbox or can be mounted to our semiflush plate for recessed electrical boxes. They are also available in combination with System Sensors Multivalent MA-12/24D horn for both visible and audible signaling.
FEATURES
- Works on two-wire circuit.
- No synchronization module required.
- Synchronized and unsynchronized strobes can be combined on the same zone in any combination.
- Patent pending Sync Circuit.
- 24 VDC versions only (for synchronization).
- 15 and 15/75 candela versions available.
- Available with Multi-Alert Sounder (MA-12/24D).
- Constant current draw over voltage range.
- Stand-alone strobe mounts to single-gang box with -SF plate.
- ADA compliant, UL 1971 listed.
- Installer easy plug-in terminal strip on stand-alone strobe.
- Strobe flashes are synchronized within individual zones to reduce the risk of seizure for people with photosensitive epilepsy.
APPLICATIONS
All Series SS24ADAS strobes are suitable for primary signaling in public mode
life safety applications. The strobes can be connected to the alarm indicating
circuit of a UL listed fire alarm control panel. They are compatible with DC
line supervision. Panels may have full-wave rectified, unfiltered power
supplies. The strobes are available for 24 VDC operation and can be used with
the System Sensor Multi-Alert horn. Stand-alone strobe versions incorpo- rate
these installer easy features: plug-in terminal strip, wiring guide, and strip
gauge (on back). Semiflush mount-ing is available with the addition of an MP-
SF accessory plate. When installed in a zone, the SS24ADAS and MASS24ADAS
Series devices flash simultaneously.
APPLICATIONS NOTE: SS24ADAS and MASS24ADAS Series devices operating in the
same zone will not be synchronized if energized at different times (i.e., if
more than one controller is controlling the same zone).

STANDARD LIGHT DISTRIBUTION
A polar light distribution in both horizontal and vertical directions is mandated for the strobes by the Standard UL 1971 for the Hearing Impaired, with specific minimum intensity percentages as shown in the graphs above.
ENGINEERING SPECIFICATIONS
Strobe shall be a System Sensor Model __ listed to Standard UL 1971 for
the Hearing Impaired and shall be approved for Fire Protective Service. Strobe
shall be wired as a Primary Signaling Notification appliance. Strobe shall
also comply with the Americans with Disabilities Act requirements for visible
signaling appliances. Strobe shall operate at 24 VDC from a regulated DC
supply or full-wave rectified, unfiltered supply. The signaling strobe shall
be powered from a non-coded power supply when powered with the horn or powered
independently. Visual signaling devices are to be installed in all non-
sleeping/corridor and sleeping areas (110 cd only) per plans and
specifications. The strobe light shall consist of a xenon flash tube and
associated lens/reflector system. Each strobe shall be designed for one flash
per second over all operating conditions. All strobes shall be capable of
mounting to a standard 4″ (101.6 mm) x 4″ x 1-1/2″ (38.1 mm) backbox, in
either a surface mount or semiflush mount with separate mounting plate.
Strobe shall flash synchronously with other SS24ADAS and MASS24ADAS Series
devices in the same zone for a minimum of 15 minutes.
NOTE: SS24ADAS and MASS24ADAS Series devices operating in the same zone
will not be synchronized if energized at different times (i.e., if more than
one controller is controlling the same zone).

- See tone selection diagram below for tab clip removal and storage.
- This selection was previously identified as Bell/Chime. This tone may be used for private or public mode in the fire alarm service when used with a 24-volt panel.
- All models can be powered using full-wave rectified unfiltered supplies. Under no circumstances can SS24ADAS or MASS24ADAS series devices input voltage exceed 33 VDC or be less than 16 VDC (18 to 33 VRMS for full-wave rectified, unfiltered supplies).
- Measured at 10 feet (3.048 m) in an anechoic chamber. For average outputs, the acoustical output shall meet the current requirements of UL Standard 464.
- Measured in a UL reverberant room.
