Mounting (Wall or Ceiling)
1.  Attach mounting plate to junction box as shown in Fig-
ure 6. The mounting plate is compatible with 4˝ square, 
double  gang,  and  4˝  octagon  junction  boxes  (2-wire 
products may be used with a single gang box). If using 
a back box skirt, attach the mounting plate to the skirt 
and then attach the entire assembly to the junction box 
(see Figure 7).
  NOTE:  For  outdoor  applications,  the  product  must  be 
installed  using  the  proper  SpectrAlert  Advance  water-
tight junction box. The wall mount watertight junction 
box must be mounted with its internal post in the lower 
left corner as shown in Figure 8.
2.  Connect field wiring according to terminal definitions.
3.  If the product is not to be installed at this point, use the 
dust cover to prevent contamination of the wiring termi-
nals of the mounting plate.
4.  To attach product to mounting plate, hook tabs on the 
product  housing  into  the  grooves  on  mounting  plate. 
Then, swing product into position to engage the pins on 
the product with the terminals on the mounting plate. 
Make sure that the tabs on the back of the product hous-
ing fully engage with the mounting plate.
5.  Secure product by tightening the single mounting screw 
in the front of the product housing.
  NOTE:  Standard  captured  mounting  screw may be  re-
placed with enclosed torx screw for tamper resistance.

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.

are designed to provide reasonable protection against harmful interference when the 
equipment is operated in a commercial environment. This equipment generates, uses, 
and can radiate radio frequency energy and, if not installed and used in accordance 
with the instruction manual, may cause harmful interference to radio communications. 
Operation of this equipment in a residential area is likely to cause harmful interference 
in which case the user will be required to correct the interference at his own expense.
