Do you have a question about the LEGRAND 643087 and is the answer not in the manual?
Avoid garages, high airflow areas, peaked ceilings, extreme temperatures, dusty environments, and areas with high condensation.
Uses a 3V non-replaceable lithium battery for backup, lasting 1-3 months with AC power off, with an estimated 10-year life.
Alarms may not detect fires behind doors or on different floors. May not wake sound sleepers or the hearing impaired.
Dust, smoking, and cooking fumes can cause false alarms. Use Hush Control near kitchens.
Create a floor plan with escape routes, hold family meetings, practice drills regularly, and establish a meeting place.
Leave immediately, check doors for heat, stay low, go to the meeting place, and call the fire brigade from a neighbor's home.
Must be installed by a licensed electrician, for indoor use, not for dusty/humid areas, no user serviceable parts.

This document provides comprehensive installation, operation, testing, and maintenance instructions for a professional flush-mounted photoelectric smoke alarm. It also includes important safety guidelines, recommended alarm locations, and warranty information.
This device is a professional flush-mounted photoelectric smoke alarm designed to detect the presence of smoke, providing an audible alarm to alert occupants of a potential fire. It operates on a continuous 230-240V a.c. 50Hz circuit and includes a non-replaceable 3V lithium battery for backup power in case of AC power failure. The alarm is designed to be interconnected with other compatible smoke alarms, ensuring that all interconnected units sound an alarm when one detects smoke. This feature is crucial for comprehensive fire detection across multiple rooms or floors within a single-family living unit. The photoelectric sensing technology is generally more effective at detecting slow-smoldering fires, which produce large smoke particles, compared to ionization alarms.
The smoke alarm is designed for indoor use and is intended for domestic or similar applications. It is not suitable for commercial installations or environments heavily laden with dust, constant vibration, extreme temperature fluctuations, or high humidity.
Upon proper installation and connection to AC power, the alarm indicates its operational status through two LED indicators:
The device incorporates a False Alarm Hush Control Feature, which allows temporary desensitization of the alarm for approximately 10 minutes. If the alarm sounds due to a nuisance event (e.g., cooking fumes), pressing the "HUSH/TEST" button on the alarm cover will silence it immediately. During this desensitized period, the red LED will flash every 15 seconds. After 10 minutes, the alarm automatically reactivates and will sound again if combustion particles are still present. This feature can be used repeatedly until the air clears.
Regular testing is crucial to ensure the alarm's functionality. The alarm should be tested monthly. To test, ensure the alarm is connected to AC power (green LED is ON). Press and hold the "HUSH/TEST" button for 5 seconds. This action should trigger the alarm, confirming that all electronic circuitry and the horn are working. If no alarm sounds, check the wiring, fuses, or circuit breaker, and confirm that the alarm is connected to a continuous final sub-circuit. For interconnected units, holding the test button on one unit will cause all connected units to sound. Continuous chirping, erratic noise, or a low sound from the alarm may indicate a defective unit, in which case it should be returned to the place of purchase. For an accurate test of the sensing chamber's integrity, a smoke detector (aerosol) tester should be used, but only after the alarm's desensitized period following a "HUSH/TEST" button test.
To prevent false alarms and ensure optimal performance, avoid installing the smoke alarm in the following locations:
For optimal fire detection, follow these guidelines for alarm placement:
Develop and practice a fire escape plan with your family:
The smoke alarm is virtually maintenance-free. However, under dusty or greasy conditions, it is recommended to clean the exterior of the unit (including the slots on the cover) using a vacuum cleaner every six months. Do not immerse the unit in water or spray it with household cleaners.
The 3V non-replaceable lithium battery has an estimated 10-year life under normal working conditions. The alarm is designed with a 10-year lifespan from the date of installation, after which it should be replaced. If the unit emits a chirping sound every 60 seconds, it indicates that the Electronic Unit needs to be replaced.
