The Cato ALC22011, previously catalogued as the 220-S, is a surface mount protective cover for a manual fire alarm pull station. A clear cover sits over a red backbox, so the station underneath stays visible and readable while gaining a deliberate second action before it can be pulled. The cover is labeled PULL TO OPEN across the lift tab and carries vertical FIRE lettering on the side, and the pull handle is designed to ADA specifications.
Why a cover
Pull stations are mounted at exits and along paths of egress where they are easy to reach, which is also where they get bumped by carts and equipment, tampered with, or pulled on purpose. Schools, gyms, dormitories, correctional and behavioral-health facilities, and warehouses see this most. A cover protects the device. It does not change how the alarm system is designed, installed, or inspected.

Related options and parts
The series also includes a recessed pull-to-open cover (ALC22001, previously 220-R) and secured break-bar versions for locations with repeat malicious activations (ALC22012 surface, ALC22002 recessed). A gasket option is available on any of them. Ask us for a model or part not listed here.
Placement
Pull station location, spacing, and inspection intervals are set by NFPA 72 and the local fire code. This cover is an accessory and is not a substitute for any requirement in that standard. Confirm the cover matches your pull station footprint before ordering.
Frequently Asked Questions
Will this cover fit my pull station?
It fits a station inside 6-1/2 in wide × 7-1/2 in high × 3-1/4 in deep, which covers common single-gang manual pull stations. The cover measures 7-1/2 in × 8-1/4 in on the wall and projects 3-3/4 in. Measure your station and its backbox against those interior dimensions before ordering — pull stations vary by manufacturer, and this cover mounts over the station rather than replacing it.
Does the cover stop the pull station from working?
No. It adds a deliberate second action before the handle can be reached, and the station underneath operates normally once the cover is opened. The cover is a passive accessory: it does not wire into the fire alarm system, and it does not change how that system is designed, installed, or inspected under NFPA 72.
Does anything need replacing after the cover is opened?
No. This is the unsecured pull-to-open version: the cover lifts by hand and reseats, with nothing consumed and no tool or key needed. If the site is seeing repeat malicious activations rather than accidental bumps, the secured version uses a scored acrylic panel and a break bar instead.
What comes in the box?
The cover, mounting hardware with nylon anchors, and the UV-resistant decals. The surface-mount body includes top and bottom electrical cut-outs fitted with black nylon snap-in dome plugs. A gasket is available as an option, and replacement decals are orderable separately. Ask us for the gasketed build or any individual part.
Is it made in the USA?
Yes. Cato / Activar manufactures these covers in the United States from injection-molded high-density polypropylene.
