Smoke & Gas Detector Insect Screen (UL 217 / EN 14604) is used for keeping insects, spiders and dust out of the sensing chamber of smoke, heat and gas detectors so they do not cause false alarms or hide real smoke.
Aperture: Openings around 0.4 mm stop small insects while letting smoke enter freely; listing standards cap the maximum size.
Form: Ring screens wrap the chamber; caps cover single sensor openings.
Material: SS304 resists humidity in bathrooms, kitchens and unheated spaces.
Materials
Standard supply is stainless steel 304; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.
Fitting & Care
Vacuum detectors from the outside once or twice a year to clear dust from the screen.
Never paint over detectors — paint closes the screen and blocks smoke entry.
Common Mistakes
Choosing too fine a screen, which slows smoke entry and response time.
Leaving out the screen in rural or warm sites, where insects trigger nuisance alarms.
When Smoke & Gas Detector Insect Screen Is Not the Right Choice
Not a filter for kitchen grease or cooking steam; nuisance alarms there need a different detector type or location.
Smoke & Gas Detector Insect Screen is made to order as finished parts. Indicative pricing starts from about US$0.060 per piece for a standard size at production quantity; the final price depends on size, material, finish, tooling and order volume.

What is Smoke & Gas Detector Insect Screen used for?
Keeping insects, spiders and dust out of the sensing chamber of smoke, heat and gas detectors so they do not cause false alarms or hide real smoke.
Why do smoke detectors have an insect screen?
Small insects entering the chamber scatter light and cause false alarms; the screen keeps them out.
Can a dirty insect screen stop a smoke alarm working?
A heavily dust-covered or painted screen slows smoke entry; clean detectors regularly.
How do I clean a smoke detector screen?
Use a vacuum brush attachment around the vents; do not open sealed units.
