Door Contact


DC-15-ULE is a Door Contact that monitors opening and closing of doors, windows, cabinets or drawers. The control panel will be alerted if there is any irregular activity.

DC-15-ULE uses a CR2 3V lithium battery as power source, particularly designed to enhance operational efficiency, lower power consumption and reduce maintenance costs. DC-15-ULE also sends regular supervision signals to check system integrity. Its tamper protection is against unauthorized opening of its enclosure or removal from its mounting surface.

With compact and low-profile design, this easy-to-install door contact can blend in seamlessly with today’s modern homes. DC-15-ULE’s fusion of thoughtful features makes your residence a more secure and convenient place without compromising home aesthetics.
