Magnetic Locks/Controlled Entry

A magnetic lock is a simple locking device that consists of an electromagnet and armature plate. By attaching the electromagnet to the door frame and the armature plate to the door, a current passing through the electromagnet attracts the armature plate holding the door closed. The strength of today’s magnetic locks compare well with conventional door locks and cost less than conventional light bulbs to operate. All magnetic locks will work only with DC current, usually 12 to 24 volts. Never connect a magnetic lock to AC current of any voltage. You may come across a mag lock that comes with an AC power supply but here the AC voltage is being converted to DC in the lock. All magnetic locks are fail safe. This means that they need a constant source of current to remained locked. If power is removed the lock will open. If this is a concern use a back-up power supply. All magnetic locks are silent even when powered and locked. 300 pound pull magnetic locks work well in light duty installations such as cabinetry. 1200 pound pull magnetic locks are great for serious locking and controlled traffic flow on normal sized doors.

Entry can be controlled by several methods:

	Keypad – Where a number sequence will open the door
	Card reader – a unique card issued to users can be swiped to open the door, a log can store access information for future use.
	Biometric Reader – a person’s unique fingerprint can be used to open the door.
	Remote control – a wireless remote can be used to open the door.
	Push Button – a push button can be placed at a receptionist area inside the building to “buzz” people in.

Exit can be controlled by several methods as well:

	Motion Sensor – a motion sensor can be placed near the exit door and the door will unlock automatically when someone is leaving and gets near the door.
	Push Button – a push button can be placed at the door or a receptionist area, and can be pressed to unlock the door when someone is leaving.
	Card Reader – a card reader can be used to monitor people leaving.
	Biometric Reader – Fingerprints can be used to leave as well as enter.

A magnetic lock system can allow monitoring of who came and went through a certain door and can help determine who was there during a certain time. These are used widely in industry to only allow employees into the building or only certain employees into certain doors. A card or fingerprint can be program to open the front door but not all the doors in the facility. They are very versatile and can be programmed to perform just about any way you can think of. Access to areas can be controlled and monitored. Possibilities are endless. Call us for more details.
