The Model D15 is a sensor for automatic doors which responds to motion in only one direction. When used on doorways with two way traffic, the D 15 allows the door to close sooner by sensing only the approaching traffic. This prevents heated and/or conditioned air from escaping through doorways which would otherwise remain open longer than necessary. Economy and environmental conditions are then maintained.

Key Benefits

	The D15 generates a very low power broad microwave beam, aimed to cover the same area usually covered by a floor mat activator. It is less expensive to install and easier to maintain than floor mat switches which sometimes fail prematurely because of freezing water, salt and other chemicals as well as heavy foot traffic wear.
	The D15 is available in two different patterns: narrow pattern for single opening doors and a wide pattern for double opening doors. Both patterns are adjustable and can be reduced in size proportionately to the required size.
	The D15 is quality constructed and employs solid state circuitry. Its small size and trim appearance is well-suited for any prestige doorway.

Specifications

ACTIVATING DEVICES
