A common challenge organizations of all sizes face is ensuring only authorized individuals have access.  Once a business grows to more than a few employees in size, maintaining control over the number of keys in circulation can quickly become a nightmare.  It doesn't take long even for the smallest enterprises to experience the delays, costs, and headaches of a lockout caused by lost keys.  One of the best things you can do right now for your sales office, branch, or building is eliminate your reliance on keys.  Linear IEI makes this easy to do with their 212R R style ruggedized keypad.  The 212R can handle the elements in even the absolute worst places on the planet, is completely stand-alone for easy setup and programming, and lets you quickly manage adding and deleting personnel.  Its vandal resistant design takes abuse in a high crime area too.  With the Linear IEI 212R keypad, you can stay focused on growing your sales, instead of the growing problems you will get confronted with because of pilfered, copied, lost, or forgotten keys.  Supporting up to 120 users, the Linear IEI 212R provides scalability.  As you add staff, your cost per user for this keyless entry system continues to decline, saving you even more in the long run.

Nice, Nortek

Customer Questions & Answers

  1. Q How do you change the combination to the keypad? answer now
    Asked by Mike Tyler on November 28, 2016 9:52 PM

    Instructions for the 212r can be found on the manufacturers website or via the link attached to the 212r.  

  2. A
    While the circuit is completed at the keypad once the keypad is removed out of the equation you are no longer able to complete the circuit to power the strike or magnetic lock. You can use the keypad in extreme weather however we do recommend that you help protect it with a weatherguard cover or overhang if possible as ice will still freeze over the keypad. As with any locking system they keep honest people honest and outside of a manned security guard there really is nothing to prevent someone 100% from not smashing it with a bat or rock. The next best thing to do would be to install a camera system to keep watch should anything happen.
