A small, self-contained condenser alarm system, the Loyal Alarm, is designed to deter theft and vandalism. The weatherproof and tamperproof unit rests inside, and is securely mounted to, the air conditioning unit. It is equipped with a 120-dB siren, which runs on battery power. According to the company, installation of the unit will not void the warranty on the air conditioner and is transferable to another air conditioner in the event the homeowner moves.
