STI 9610 Stopper II indoor low-profile cover for fire alarm pull stations.

Compliance

• UL listed accessory
• ADA compliant low-profile depth
• NFPA 72 compatible (does not impair pull station operation)

Key features

• Clear polycarbonate hood mounts over manual pull stations to deter malicious or accidental activation
• Low-profile depth keeps the cover within ADA reach-range limits on finished walls
• Lift-to-open design — lifting the cover does not trigger an alarm by itself
• Mounts directly to standard single-gang or double-gang pull station backboxes
• Compatible with most Fire-Lite, Notifier, and similar manufacturer manual pull stations

Protective covers like the STI 9610 are installed over manual pull stations in environments where false activations are a recurring problem — schools, public corridors, dormitories, and high-traffic commercial spaces. The clear polycarbonate hood remains visible so occupants can see the station underneath, but the act of lifting the hood serves as a physical and visual barrier that discourages casual or malicious activation. The 9610 variant is the indoor low-profile model without an integral piezoelectric alarm; STI manufactures variants with a built-in horn (alarm-equipped covers) and outdoor weatherproof versions for installations that need additional deterrence or environmental protection.
