The Company shall not be obligated to repair or replace units which are
found to be defective because of damage, unreasonable use, modifica-
tions, 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 negligence or fault.
Some states do not allow the exclusion or limitation of incidental or conse-
quential damages, so the above limitation or exclusion may not apply to
you. This Warranty gives you specific legal rights, and you may also have
other rights which vary from state to state.
System Sensor’s sounder and signal strobe is designed to provide fire and
security hazard warning.
The strobe is for supplementary signaling use only.
The sounder or sounder/strobe combination will not work without
power. The sounder or sounder/strobe gets its power from the fire or se-
curity panel monitoring the alarm system. If power is cut off for any rea-
son, the sounder or sounder/strobe combination will not provide the
desired audible 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 in an area which is isolated by a closed door, or if it is located
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, machin-
ery, or music appliances that may prevent alert persons from hearing the
alarm. The sounder may not be heard by persons who are hearing im-
paired.
The signal strobe may not be seen. The electronic visual warning signal
meets or exceeds current Underwriters Laboratories’ standard 1638. The
visual warning signal is suitable for direct viewing and must be installed
within an area where it can be seen by building occupants. The strobe
must not be installed in direct sunlight or areas of high light intensity
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, in-
cluding this strobe, are activated.

factory for repair or replacement.
PS12 or PS24 Strobes
These optional strobes are interconnected to the PA400 by first re-
moving the two mounting screws from the sounder. Use a small
screwdriver to punch out the skinned-over areas as indicated in
Figure 6. Install the adapter plate on top of the sounder and screw
the combined sounder and adapter plate to the electrical outlet
box. Make sure field wiring terminals are oriented in the upward
position when mounted in the outlet box. Next, slide the strobe
directly into the slots in the plates. The positive solder lug may be
colored red or marked with a plus sign (+). This lug must be in
the slot closest to the field wiring terminals. Grasp the catch area
on each end of the strobe and squeeze while applying inward
force. Make sure the strobe catches fully engage the slots in the
adapter plate and that no gap appears at the interface between the
strobe and adapter plate.

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 pro-
vide 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 condition-
ers, 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 Un-
derwriters Laboratories’ standard 1971 and uses an extremely reliable xe-
non 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-
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 disre-
garded or not seen. The strobe may not be seen by the visually im-
paired.
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, in-
cluding 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 unin-
terrupted source of DC power in order to operate correctly.
