Understanding Fire Alarm Checks
Fire alarm checks, also known as fire alarm inspections or testing, are comprehensive evaluations of a fire alarm system to ensure it is fully operational and compliant with safety regulations.
The three main types of fire alarms are:
1. Conventional fire alarm systems: It divides the building into zones, with detectors wired in zones to the control panel. When an alarm triggers, the panel indicates only the zone, not the exact device location. They are cost-effective and simpler and are suitable for smaller buildings.
2. Addressable fire alarm systems: Each device (smoke detector, manual call point, etc.) has a unique address and the control panel pinpoints the exact device and location of the alarm. Supporting advanced features like event logs, pre-alarms, and programmable thresholds, they are more suitable for large or complex buildings. However, they are costly and complex to install.
3. Wireless fire alarm systems: They use radio frequencies to communicate between devices and the control panel, eliminating the need for extensive wiring. They are cheaper and easy to install, offering greater flexibility for relocation or maintenance.
