To keep your alarm in good working order, you must follow these steps:
• Test the alarm once a week by pressing the Test/Reset button.

• Never use detergents or solvents to clean the alarm. Chemicals can
permanently damage or temporarily contaminate the sensor.

contamination of the sensor, prior to performing any of the following:
• Staining or stripping floors or furniture, painting or wall-papering,
• Using aerosols or adhesives
