Now I will provide information about the magnetic door locks. Magnetic door locks consists of an electromagnet. Magnetic door locks are suitable when used for the doors that are not too heavy. Outside, the mechanical locking systems and magnetic key like this can not stand when exposed to water, but there are some products that have resistance to water.
There are two kinds of models for this magnetic door locks, which are:
- The E version (unlocked under voltage) is mostly used for machine safety
- The R version (locked under voltage), is mostly used for fire doors.
The general workings of a magnetic door lock has a magnetic reader which reads a magnetic code on a key moved past the reader and communicates the code to a control device having electronic logic circuits which compare the key code with a lock code. When the two codes correspond, the control device will energize an electromagnet which moves a locking armature from a catch on a locking bar, allowing the bar to be withdrawn from the door frame and the door to be opened. Over time, especially when outdoors, locks and keypads become grungy. Dirty reader heads inside the card slot can also cause card reader malfunction. Magnetic door locks are operated by electricity, so it is important when cleaning to not allow water or cleaning fluids to seep into the keypad or card reader and cause damage to the electronics.
The steps that can be used to clean magnetic door locks are
- Switch off the main supply of electricity for these magnetic keys
- Spray the key with an air compressor to dust clinging to these magnetic keys. Be sure to hold the can of compressed air in an upright position so no liquid drips out.
- Clean the surfaces, keypad buttons and mouth of the card slot with antibacterial wipes or a lint-free cloth dampened with rubbing alcohol. Ring out the wipe or cloth to remove excess moisture before using it. Twist it and let it drip until no more drips come off. This will ensure that no moisture will get underneath the keys or seep into any seams or cracks. Do not spray cleaning product directly onto the lock. Wrap the cloth around one finger to help get into small areas and corners. Cotton swabs and balls can also be used if necessary.
- Clean the inside of your card reader slot with a card reader cleaning card. Cleaning cards can be purchased from credit card supply companies. Insert the cleaning card into the slot five or six times, just like you would a regular card. Wait one minute to let the card and reader dry. Insert the cleaning card into the slot five or six more times. Throw away the card.
