Fire Alarm Detectors — buy PacsEngineering brand
PacsEngineering fire alarm detectors are highly sensitive devices designed for early detection of fire indicators — smoke, heat, gas, or flame. The correct choice and installation of detectors directly affect safety, property protection, and the overall efficiency of the fire alarm system.
Purpose and principle of operation
Detectors (sensors) from PacsEngineering perform the key function of detecting a fire at an early stage and transmitting a signal to the control panel.
Once the threat is detected, the system activates:
• Audible and visual alarms;
• The fire suppression system (if available);
• Evacuation and notification scenarios.
Externally, detectors are compact ceiling- or wall-mounted devices that operate 24/7, automatically responding to changes in air parameters typical of fire development.
Types of PacsEngineering fire alarm detectors
1. Heat detectors
React to an increase in temperature within a room.
Inside the device are heat-sensitive elements that detect critical temperature values or rapid temperature rises.
Advantages:
• Reliable in humid or dusty environments;
• Resistant to electromagnetic interference;
• Suitable for kitchens, industrial workshops, and warehouses.
Types:
• Fixed-temperature — activate when a set threshold (e.g., 70 °C) is reached;
• Rate-of-rise — respond to rapid temperature increases.
2. Smoke detectors
The most common type used in residential and office environments.
They respond to smoke particles in the air, allowing fire detection even before open flames appear.
Types:
• Optical (photoelectric) — a light beam is refracted by smoke particles, triggering the sensor;
• Ionization — monitor air density and ion balance.
Advantages:
• High sensitivity;
• Early detection of smoldering and short circuits;
• Compact size and easy installation.
3. Gas detectors
Detect leaks of carbon monoxide (CO), methane (CH₄), and other hazardous gases.
Operate through electrochemical analysis of air composition.
Features:
• Instant response (within 5 seconds of gas presence);
• Adjustable sensitivity threshold;
• Ideal for boiler rooms, kitchens, basements, and parking garages.
4. Flame detectors
Respond to open flame — ultraviolet or infrared radiation.
Used in industrial facilities, fuel depots, oil terminals, and explosion-hazard areas.
Types:
• Addressable — pinpoint the exact flame source;
• Explosion-proof — suitable for hazardous industries;
• IR/UV models — analyze the optical spectrum for maximum accuracy.
5. Multi-sensor (combined) detectors
Combine multiple detection methods (e.g., smoke + heat).
Trigger when several parameters are exceeded, reducing false alarms.
Advantages:
• High accuracy of fire detection;
• Suitable for critical environments;
• Reliable and versatile.
6. Manual call points
Activated manually by pressing an emergency button.
Mounted on walls near exits or along evacuation routes.
Features:
• Manual fire alarm activation;
• One-time or resettable operation;
• Mandatory for public buildings (offices, schools, shopping centers).
Installation and operation
• Typically ceiling-mounted for maximum smoke and heat detection.
• Wall or combined installations are used in large spaces.
• Each detector covers a defined area depending on its type and ceiling height.
• All detectors are connected to a PacsEngineering fire control panel that analyzes signals and triggers suppression or alert systems.
Advantages of PacsEngineering detectors
• High precision and stable operation.
• Compatibility with both addressable and conventional systems.
• Simple installation and maintenance.
• Backup power and false alarm protection.
• Integration with fire suppression, ventilation, and access control systems.
