This set of two mini smoke detectors from Alecto is intended for detecting smoke and providing an acoustic warning signal when smoke develops. The product is used for fire detection in indoor spaces and is suitable for use in homes, bedrooms, hallways, and office environments. The smoke detectors operate on the basis of optical smoke detection and react to smoke particles in the air. Despite their compact size, the smoke detectors produce an alarm signal of 85 decibels, which is intended to be audible to occupants in the room. The smoke detectors are equipped with 3-volt batteries with a stated battery life of five years. Each smoke detector has a test button and a reset button for manual function testing and resetting after activation. Applications • Smoke detection in living areas • Smoke detection in bedrooms • Smoke detection in hallways and landing areas • Smoke detection in office and practice spaces Specifications & Features • Brand: Alecto • Type: Mini smoke detector • Quantity: 2 pieces • Detection type: Optical smoke detection • Alarm sound level: 85 dB • Power supply: Battery powered • Battery type: 3-volt batteries • Battery life: five years • Operation: Test button and reset button • Mounting: Ceiling mounting • Casing: Plastic • Color: White • Certifications: EN 14604, NBN EN 14604, CE Explanation of power supply Battery-powered means that the smoke detectors are powered by batteries and function without being connected to the mains. Explanation of additional features Set of two smoke detectors The package contains two separate smoke detectors that can be used simultaneously in different rooms within a home or building. Mini and compact design The smoke detectors have a small size and are designed to be less noticeable after mounting on the ceiling or wall. Battery life of five years The batteries are designed to supply power for a period of five years under normal use. Test and reset function The test button allows for manual function checking, and the reset button allows the smoke detector to be reset after activation. Explanation of detection types Optical smoke detection works by measuring smoke particles in the air using a light source and sensor. When smoke disrupts the light beam, the alarm is activated. Ionization smoke detection works by measuring changes in an electrical current between two electrodes when smoke particles are present. Thermal detection measures temperature changes and activates the alarm when there is a rapid temperature increase or a fixed value is exceeded. Combination detection combines multiple detection methods in one detector. Carbon monoxide detection measures carbon monoxide gas and is intended for gas detection, not smoke detection. Explanation of standards EN 14604 is the European product standard for smoke detectors and describes requirements for smoke detection, alarm volume, reliability, and test methods. NBN EN 14604 is the Belgian adoption of the European standard EN 14604 with the same technical requirements. CE indicates that the product complies with the applicable European directives concerning safety, health, and environmental protection. Ask a product question
