Stopper® II
S2466
Overview
Standard Features
This unique and patented device helps to prevent false fire alarms
without restricting legitimate alarms. It consists of a tamper-proof,
clear Lexan polycarbonate shield and frame that fits easily over
manual pull stations. When lifted to gain access to the actual
alarm, it sounds a piercing warning horn. Immediate attention is
drawn to the pull station and a prankster will run or be caught.
Legitimate alarms can still be pulled.
• Fits virtually all pull stations
Use proven in thousands of applications around the worldincluding colleges, schools, hospitals, nursing homes, correctional
institutions, hotels/motels and stores.
• Weatherproofing option
• Tested and approved by wide range of fire prevention and testing authorities
• Unconditional lifetime guarantee against breakage and damage
to molded polycarbonate cover
• Guards against physical damage to manual pull station
• Optional 9-volt alkaline battery (included) powered horn

Dimensions
Size of Pull Station Accommodated
The Stopper II can be installed over a flush-mounted station up to
5½ inches (140mm) wide x 6¾ inches (171mm) high. However,
the pull station’s maximum dimensions will decrease as its depth
(distance from wall) increases. e.g.:
3¼ inch (19mm) deep pull station may be
5 inches (140mm) wide x 6 inches(152mm) high
1-5/8 inch (41mm) deep pull station may be
5 inches (127mm) wide x 6 inches (152mm) high
2-3/8 inch (60mm) deep pull station may be
4 inches (102mm) wide x 5 inches(146mm) high
2 inch (70mm) deep pull station may be
3 inches (76mm) wide x 5 inches (140mm) high
NOTE: If additional depth is needed, use the Conduit Spacer (Part
No. STI 3100) which adds 2 inches (51mm) to the depth.
Patent Approval
Stopper II has received patent approval from the United States
(No. 4267549) and Canada (No. 1147828Z). Patents for other
countries are pending.
Mounting
Two types of mounting are available.
Flush-mounted means the pull station is mounted directly on the wall.
Surface-mounted means the pull station is mounted on an electrical box
away from the wall.
Surface Mounted: When the pull
station is mounted on an electrical
box away from the wall, order Part
No. STI 1130 (with horn) or Part
No. STI 1230 (without horn). Each
includes longer screws with anchors
and a 2 inch (51mm) conduit spacer
(Part No. STI 3100) with knockouts
top and bottom to accommodate the
conduit pipe.
For Added Weatherproofing
Install gasket (STI 3002) between
Stopper Il frame and wall. A second
gasket must be installed behind the
spacer for surface mounting.
A conduit gasket (STI 3003) may be
used to seal the conduit pipe.

IMPORTANT NOTICE
Adequate training and instruction must be provided to avoid the possibility that persons, in the event of a real fire, lift the Stopper II cover,
hear the horn and think they have set off the fire alarm.
1. Explain the purpose of the Stopper II to authorized personnel.
2. Show them how it works.
3. Instruct them to, upon hearing the Stopper II horn, check for the presence of a fire, and act accordingly by either pulling the fire
alarm or shutting off Stopper II by closing the cover.
4. Check with your local fire authorities.
5. When covering a pull station, UL requires stations to be listed for
outdoor use.
