Material and build: Heavyduty iron construction provides a rugged protective shell for detector heads and alarm sensors. Built to withstand harsh conditions and repeated impacts. Primary function: Protects the sensor and alarm head from physical damage, preserving detector functionality and preventing false or failed alarms caused by bumps, knocks, or accidental contact. Explosion prevention: Explosionproof mesh design vents heat while reducing the risk of sparks, fires, or ignition sources reaching the sensor element. The mesh helps minimize fire and explosion risk without blocking detector operation. Wire and component protection: Acts as a guard for alarm wiring and detector components, keeping cables and connections shielded from accidental damage or tampering. Durability and longevity: Corrosionresistant iron and robust construction ensure long service life and reliable protection in demanding environments. Practical performance: The cover maintains sensor access to air flow and signal pathways while preventing direct impact and debris contact, helping detectors continue to perform as intended. Use scenarios and applications: Industrial and manufacturing sites where machinery, tools, or moving equipment could strike ceiling or wallmounted detectors. Public and commercial buildings (corridors, stairwells, lobbies) to protect alarm heads from accidental impacts, vandalism, or tampering. Kitchens, storage areas, and warehouses where elevated heat, debris, or rough activity require added protection and explosion‑risk mitigation. Key benefits at a glance: Preserves detector accuracy and function by preventing physical damage Reduces fire and explosion risk with an explosionproof mesh design Shields wiring and alarm components from accidental harm Durable iron construction for reliable, longterm protection Note: Designed as a protective cover and guard for alarm heads and detector sensors; material and features prioritize impact resistance, corrosion durability, and explosionmitigation.
