• Be Underwriters Laboratories (UL) or Factory Mutual (FM) approved.
• Have a backup power or battery system that prevents activations in a power outage.
• Possess an automatic entry and exit delay system.
• Allow users to test the system internally for malfunctions.
• Have a surge protector to prevent power outages due to harsh weather conditions.
