STI – Fire Pull Station Protective Covers

Universal Stopper^®

Protective Cover You Can Build Your Way

Unique device provides unmatched protection against false fire alarms and allows user to build the cover for their specific needs.

This indoor/outdoor polycarbonate cover protects devices such as dual action pull stations, keypads for entry systems, intercom stations, emergency buttons, electrical light switches, duplex plugs, etc., without restricting legitimate operation. The cover, with or without horn, is available in flush mount, surface mount or waterproof backbox (pending) models. It is low profile (less than 4 inches) and has the same footprint as the Mini Stopper^® but accommodates most dual action pull stations.

• Protects against vandalism, accidental damage, dust and grime and severe environments inside and outside (testing pending)
• Protects pull stations, keypads, intercom stations, emergency buttons, electrical light switches or duplex plugs
• Cover is molded from thick, super tough polycarbonate material
• Flush frame, surface frame or waterproof (listing pending) mounting options
• Top and bottom of waterproof (listing pending) backbox are threaded for 3/4" NPT rigid conduit
• Sized to fit most pull stations
• High strength continuous hinge
• Optional relay output with 12-24 VDC power input
• Low profile – ADA Compliant (listing pending)
• Gaskets included
• Locking tab (not for use with fire pull stations)
• Models available with or without 105 dB horn
• Available with red, green, blue, yellow, white or black message hood/horn housing with custom or no label
• Available for red units "In Case of Fire..." label.
• UV-stabilized to keep cover clear
• Typical working properties of polycarbonate are -40° to 250°F (-40° to 121°C)
• No charge for custom label
• Lifetime guarantee against breakage of polycarbonate in normal use (one year on electro mechanical and electronic components)

Universal Stopper helps prevent false fire alarms without restricting legitimate alarms. It consists of a clear, tamperproof polycarbonate shield and frame that fits over manual pull stations. When lifted to gain access to the actual alarm, models with alarm will sound a piercing, self-contained, warning horn. Immediate attention is called to the area and a prankster will either run or be caught. The unit is offered in green, blue, yellow, white and black for use in covering an array of devices.

Universal Stopper is ideal for colleges, schools, hospitals, nursing homes, training centers, correctional facilities, hotels/motels, stores, libraries...public buildings of almost every kind where the threat of false fire alarms is great. Stronger than steel pound for pound, its almost unbreakable polycarbonate construction makes it suitable for abusive environments such as warehouses and correctional facilities.

How well it works is evident by its loyal following throughout the security and fire prevention industries...as well as its intense owner loyalty.

Unique device provides unmatched protection against false fire alarms from pranksters and vandalism.

Gladys S. Haymore, Assistant Business Manager
Masonic and Eastern Star Home of N.C., Inc.
Greensboro, North Carolina

"We care for 200 children, ages one month to five years. Pulled false alarms were frequent, to the point where we were going to be charged for more. Hence, our installation of six Stopper II units. WE HAVE HAD NO FALSE FIRE ALARMS SINCE. That, and they are nice looking."
Mary Ann Ranspach, Registered Nurse, Admin. Staff
Florence Fuller Child Development Center
Boca Raton, Florida

"We have over 50 Stopper II units and I can tell you...they work!"
Bill Vanden Heuud, Risk Manager

"Over the past four years, our guests have set off one of our ten Stopper II units a number of times. Without the Stopper, there would have been a false alarm each time...eight times at night."

"We had trouble with moisture and resulting false alarms. Not so, since we installed our Stopper II units."
Thomas De Brosse, Facilities Engineer

"The Stopper II has decreased our false alarms greatly. Our units have been installed over two years and we haven't had any false alarms. Prior to installation, we averaged one a month. Our Stopper II units are used in state office buildings, district court and our multi-service center."
Allan E. Blackiston, Maintenance Supervisor
State of Maryland Department of General Services

These accessories can greatly extend the usefulness of the Stopper II device. Conduit spacers are available in red, green, blue, yellow and clear, a mounting backplate for use on irregular surfaces (recommended for weather applications), weather gaskets, a heater kit for operation in cold weather areas, a conduit gasket, a rigid conduit gasket, a 3/16" allen wrench, and a replacement horn complete with 9 VDC battery.

Also available for the spacer units are grills and louvers to help eliminate fogging inside the Stopper II in outdoor applications. The SUB315 grill (ships with all new Weather Stopper models and is required to meet NEMA 3R criteria) is recommended when a Stopper II cover is installed out-of-doors over a manual pull station or other device containing heat-generating electronics. In most cases, this is all that is needed to solve the problem of fogging.

For areas where condensation and fogging are more severe, the optional SUB316 vented louver kit may also be installed. The louvers are installed in addition to the grill kit to provide additional ventilation and drainage of any collected moisture.

Stopper II has been tested and approved or listed by:

• Underwriters Laboratories and Canadian UL, No. 49G2
• Underwriters Laboratories of Canada Issue No. CS550. (STI 1100 & 1200 only)
• Factory Mutual No. OG6A2.AY (STI 1100 only)
• New York City Board of Standards No. 947-81-SA
• State of California (approval not required). Obtaining local Fire Marshal approval prior to installation in California is required
• ADA Compliant (UL Certified NO. S2466)
