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 bever-
ages. 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.

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 in-
stalled 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.
