SENTRY™ pull station covers from SigCom protect manual fire alarm pull stations from false alarms, vandalism, dust, and weather. Specifically, each cover is molded from rugged, UV-stabilized clear polycarbonate. As a result, the station stays visible while staying protected. Furthermore, the bottom-hinged door opens a full 200° for unobstructed access.
SigCom designed the SENTRY line for ADA compliance (28 CFR Part 36). For example, the cover opens with one hand and less than 5 pounds of force. It also protrudes less than 4 inches into corridors. In addition, raised lettering and Braille instructions appear on every cover. The covers are UL listed and CSFM approved.
Most surface-mount manual pull stations install easily behind a SENTRY cover. Therefore, one cover line serves indoor and outdoor applications across many station brands. Below are the five SENTRY kits we stock.
SENTRY Front Cover Kit: ST-FRC01
The ST-FRC01 is the standard SENTRY front cover. It measures 10″ H x 7-1/4″ W x 1-3/4″ D. In addition, it ships with four #10 type A, 1-3/4″ Phillips round-head screws with anchors. Those anchors suit standard wallboard installation. Use it alone for flush-mounted stations.
SENTRY Weatherproof Kit: ST-WPK01
The ST-WPK01 is an optional NEMA 3R weatherproofing kit. It includes a cover gasket and two conduit gaskets. However, SigCom recommends adding the ST-BKP01 backplate to complete a weatherproof installation.
SENTRY Backplate Kit: ST-BKP01
The ST-BKP01 mounts SENTRY covers to rough surfaces. Specifically, the kit contains a plastic backplate measuring 10-1/2″ H x 8″ W x 1/4″ D. It also includes two #10 type A, 1″ Phillips round-head screws with anchors.
SENTRY Alarm Module Kit: ST-ALM01
The ST-ALM01 deters malicious false alarms in schools, hospitals, transit hubs, and other crowded facilities. When someone opens the cover, the module emits a piercing 104 dB (±3 dB at 1 meter) siren. As a result, pranksters get deterred and staff hear which cover was opened. The kit includes the alarm module, a 9V battery, a silencer key, and two 6-32 x 3/8″ screws.
SENTRY Extender Kit: ST-XTR01
The ST-XTR01 adds depth for surface-mounted pull stations. With the extender installed, the assembly measures 10″ H x 7-1/4″ W x 2″ D. Furthermore, the kit includes two conduit block plates, a compression plate, and four #10 type A, 4″ Phillips round-head screws with anchors.
Which Kits Do You Need?
For flush-mounted indoor stations, the ST-FRC01 alone is enough. For surface-mounted stations, add the ST-XTR01 extender. For rough walls, also add the ST-BKP01 backplate. Finally, for outdoor or wet locations, combine all of those with the ST-WPK01 weatherproof kit. The ST-ALM01 alarm module can be added to any configuration.
