Smoke Detector Guards
Smoke detector guards are designed to protect flush-mounted smoke detectors, fire detectors and motion detectors against vandalism, misuse and accidental damage. These protective guards help reduce maintenance costs and false alarms while preserving the intended operation of the protected detector.
What This Product Group Covers
Detector guards are especially useful in schools, public buildings, correctional facilities, healthcare environments, water treatment plants and other spaces where detectors may be exposed to impact, tampering or repeated accidental damage. Instead of replacing damaged detectors or dealing with repeated nuisance alarms, protective guards provide a physical barrier around the device while still allowing it to function correctly.
The FUMARO page presents three main types of detector protection: Steel Web Stoppers, Polycarbonate Detector Stoppers and Stainless Steel Detector Stoppers. Each version is intended for a slightly different environment and protection requirement.
Main Product Types
The page groups detector protection into three core solutions.
Steel Web Stoppers
Heavy-duty galvanised steel rod cages with corrosion-resistant coating for detector protection.
Polycarbonate Detector Stopper
Clear protective guard for detectors in areas with severe accidental or malicious abuse.
Stainless Steel Detector Stopper
Maximum protection with perforated stainless steel construction for demanding applications.
STI Steel Web Stoppers
These Steel Web Stoppers are designed to protect smoke detectors, fire detectors and motion detectors against vandalism and misuse. According to the FUMARO page, they are constructed from plastic-coated, heavy-duty galvanised steel rod and can withstand severe abuse from vandalism or accidental damage.
Where additional security is required, tamper-resistant screws and matching bits are available. This makes the Steel Web Stopper a strong option for installations where the detector needs robust physical protection.
Polycarbonate Detector Stopper
The Polycarbonate Detector Stopper is intended for smoke detectors in areas where abuse is severe, whether accidental or malicious. The page explains that this version is easy to install and is suitable where detector vandalism or physical damage is causing false alarms and high maintenance costs.
It is presented as an alternative to the steel web versions and is described as suitable for environments such as prisons and hospitals, where narrow slots may be beneficial. It is available for flush or surface-mounted applications with exposed conduit.
Stainless Steel Detector Stopper
The Stainless Steel Detector Stopper is described as a high-protection solution designed to guard vulnerable detectors without compromising effective operation. Its perforated construction allows smoke to reach the detector while providing a strong physical shield against misuse and vandalism.
The page notes that it is manufactured from heavy-duty 18 gauge stainless steel, offering natural corrosion resistance. A coated cold-rolled steel version is also mentioned, providing additional strength and durability for sites where detectors are frequently vandalised and maintenance costs are high.
