The strobe will not work without power. The strobe gets its power from the fire/security panel
monitoring the alarm system. If power is cut off for any reason, the strobe will not provide the
desired visual warning.
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 installed in direct
sunlight or areas of high light intensity (over 60 foot candles) where the visual flash might be dis-
regarded or not seen. The strobe may not be seen by the visually impaired. The signal strobe may cause seizures. Individuals who have positive photic response to visual
stimuli with seizures, such as persons with epilepsy, should avoid prolonged exposure to environ-
ments 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 cor-
rectly. 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.

Three-Year Limited Warranty
System Sensor warrants its enclosed strobe or strobe to be free from defects in materials and work-
manship under normal use and service for a period of three years from date of manufacture.
System Sensor makes no other express warranty for this strobe. No agent, representative, dealer,
or employee of the Company has the authority to increase or alter the obligations or limitations of
this Warranty. The Company’s obligation of this Warranty shall be limited to the repair or replace-
ment of any part of the strobe which is found to be defective in materials or workmanship under
normal use and service during the three year period commencing with the date of manufacture.
After phoning System Sensor’s toll free number 800-SENSOR2 (736-7672) for a Return
Authorization number, send defective units postage prepaid to: System Sensor, Returns Department, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please include a note
describing the malfunction and suspected cause of failure. The Company shall not be obligated to
repair or replace units which are found to be defective because of damage, unreasonable use, mod-
ifications, or alterations occurring after the date of manufacture. In no case shall the Company be
liable for any consequential or incidental damages for breach of this or any other Warranty,
expressed or implied whatsoever, even if the loss or damage is caused by the Company’s negli-
gence or fault. Some states do not allow the exclusion or limitation of incidental or consequential
damages, so the above limitation or exclusion may not apply to you. This Warranty gives you spe-
cific legal rights, and you may also have other rights which vary from state to state.
Mounting
If you would prefer to switch the lens colors, the strobe modules are field-
reversible. (Fig. 4)
To reverse the strobe module: insert screwdriver, as shown in Fig. 4, to
unlock snap. While pushing in the screwdriver, pull back on the strobe
module. Hinge the strobe module, disengage the Locking Rib, and lift the
module away from the mounting plate. Turn the module so that it is
upside down from its original position, re-insert the module into the
mounting plate (be sure to insert the Locking Rib into the slot), and press
the module into the mounting plate. The strobe module will make a
“click” when it has locked into place. Turn entire assembly so that the
lenses are on the bottom. The unit can now be mounted.
The unit can be mounted to a single-gang back box, or to a 4″ x 4″ back
box, using the mud ring provided.
1. Complete field wiring.
2. Align dual strobe over back box
and secure with screws.
