A fire alarm detector is a device that detects temperature rise or change in the surrounding atmosphere and provides an early warning of fire. Fire detection devices are classified into manual fire alarm detectors, automatic smoke detectors, heat detectors, photoelectric beams, gas leakage detectors, and other types based on different methods used for detecting fires. There are many types of fire detection and protection systems and devices available and there is a system for any type of application or environment.
Here are a few factors to consider when buying fire alarm detectors:
- Type of Installation
Location and type of installation will determine the type of system installed. If it is a new building, one can install any kind of system as per requirement unlike in an old building where only specific devices such as smoke detectors or heat detectors can be used. In the case of an old building, it is also better to have a backup system in place.
- Intended Use
Detectors are used mostly in office buildings, factories, and warehouses. For homes, there are specific types of detectors available such as heat detectors or smoke detectors.
- Application
If the application requires a high level of accuracy and sensitivity, photoelectric beams or heat detectors should be used. For areas where there is a risk of false alarms such as hospitals, warehouses, and laboratories, more than one device should be installed to provide redundancy and backup.
- Budget
Fire detection devices vary in price from less than $50 to several thousand depending on the type and range of the device. Installation cost has to be taken into consideration as well. One should not compromise on quality just because it is affordable or vice versa.
- Selection by Professionals
A fire detection system requires professional installation for optimal performance, especially in the case of large commercial installations with several detectors installed over the sizable area so that if one fails, the others can take over the task of detecting fire.
- Features
There are several additional features available with detectors such as a manual call point that alerts occupants about the location of the nearest exit in case there is a fire and voice evacuation system that delivers specific instructions to building occupants during an evacuation. Sophisticated systems can be programmed to automatically activate specific devices in case the heat detectors are triggered.
- Ease of Maintenance
After installation, it is important that the device is serviced regularly and maintained properly for optimal performance. One should opt for a device that has easy maintenance features such as access modules for replacement or service.
- Standardized Systems
There are several certification agencies that certify and test fire alarm systems for safety, reliability, and accuracy. One should try to choose a device that is certified by UL or FM groups.
The objective of installing fire alarm detectors is to provide an early warning of fire and enable occupants to safely evacuate the building. The costs involved in installation and maintenance should be compared with the magnitude of risks, such as loss or damage due to a major fire.
