Manual Call Point Cover vs STI Cover: Which One Should You Choose?
A manual call point cover is a protective fire safety accessory designed to prevent accidental activation, reduce false alarms, and protect emergency alarm buttons from environmental damage and misuse.
In modern fire alarm systems, protecting manual call points (MCPs) is as important as the alarm system itself. Accidental triggering, vandalism, dust, and water exposure can all lead to false alarms and system disruption.
The market is dominated by STI protective covers, but cost and installation flexibility are pushing many buyers to look for alternatives such as the SR-A08-PS manual call point cover.
Based on real product comparison data between STI cover and SR-A08-PS, this guide helps you understand which solution is better for your project requirements.

- Reduce false fire alarms
- Protect against dust, water, UV exposure
- Extend device lifespan
- Improve compliance in public environments
It is widely used in:
- Schools
- Warehouses
- Hotels
