Impulse source

The appropriate choice is important.

An activator is necessary for each automatic door system, which should be appropriately chosen to meet all the customer’s requirements. Depending on the door construction, location and opening frequency, the operation activation unit should be chosen on location. The choice of the appropriate activator and its location is crucial to the correct automatic door system functioning. Choosing the appropriate mechanism avoids problems with smooth operation.

1) MANUAL ACTIVATORS			2) AUTOMATIC ACTIVATORS
Manual activators are generally used in buildings where the users are well acquainted with the local conditions. Manual activators need to be activated on arrival by touch, physical motion, manual depression, key etc. They are generally used in buildings where the users are well acquainted with the local conditions (operating theatres, laboratories, special departments).			Automatic activators, which include radar units and infraactive sensors, are used mostly in public passages or buildings where many people pass through.
	1. REMOTE SWITCH		1. INFRAACTIVE SENSORS
		- remote switches are mainly used in hospitals where they can activate an automatic door by sensing hand motion at a distance of 10 - 50 cm (hygienic reasons). They are placed at the normal light switch height.		They are used when the door has to be opened from a smaller distance - up to 1.5m. With this kind of sensor it is possible to limit the detection field in order to approach the door from the side, or to disable the sensor for movements from the door side.
2. ELBOW SWITCH			2. RADAR UNITS
		- large wall switch activated by leaning an elbow against the tilting surface - hands remain free.		Microwave radar is the most convenient solution for heavier traffic because its detection field (the area in which it is able to detect a movement) is homogenous and inescapable. The range is up to 2.5m in front of the door. The latest microwave sensors recognize movements "towards the sensor" and "away from the sensor". In this way it is possible to shorten the AD opening time and prevent much of the heat loss.
3. FOOT SWITCH			3. COMBINED ACTIVATOR
		- foot switch in the shape of a wall button, located approximately 15-20 cm above the ground, enables the activation of the automatic door after gentle treading on the rubber cap. It can also be delivered in a foot mat shape, located in front of the door. It only enables activation in the marked place.	ACTIV8 The Activ8 is a modern source of automatic door impulses ensuring, in addition to activation of the drive, the security of persons passing through. It is a one-piece combination of a microwave radar and security infrared curtain. - It ensures opening in one direction (by detecting any movement in the direction of the sensor) - It monitors the presence of persons and ensures their security by using the curtain and 24 overlapping vertical areas; each ensuring homogenous and reliable detection.
4. PRESS SWITCH
		- used by guarded entrances, and may be replaced by a reading card scanning mechanism.
5. OUTDOOR KEY SWITCH
		- if there is a single automatic door entrance in the building, an outdoor key switch is used. It is a large, resistant box, placed in the facade near AD, controlled with a key with a safety cylinder insert. In case of power breakdown, this switch enables the activation of the automatic door from a stand-by power supply, which is a part of the automatic door drive. Secure, resistant to forcible entry and vandal-proof.
