Durable, very tough, and designed for use in harsh conditions or rough climate, the Linear IEI 212SE sealed environment keypad is a good solution for the intentional restriction of access of a door, space, gate, service, or barrier.  Instead of issuing keys or cards, you can provide staff, managers, and anyone requiring daily or temporary access a number sequence they can use for punching in on the keypad.  When their code matches a pre-programmed PIN, the keypad will relay a device with an on/off switch such as an electric strike or maglock to allow access.  Your IEI 212SE keypad also includes 4 on -board secondary relays, for user controlled operation of anything with an on/off switch, or to activate a siren.  Throughout the world, Linear IEI electronic keypads number in the thousands.  Companies and facilities rely on the second to none engineering, and capabilities of these keypads to offer protection of assets, reduce keys, and increase security, convenience, and efficiency.

    If you forgot the master code or it is not working, momentarily push SW1 (located within the unit so the keypad will need to be removed) to enter programming mode and use menu option 19 to default keypad.

    Once in programming mode by using the SW1 button, press 46 # 00000 # 00000 # ✱ ✱ on the keypad to erase all settings and default the master code back to 1234. 

  3. Q Are the contacts momentary or timed? answer now
    Asked by Ken Pierce on October 12, 2021 2:49 PM

    The contacts are a timed relay. When a valid code is entered, the relay will close for a few seconds before they reopen to lock the door. 

  4. Q Are the keys backlit? answer now
    Asked by Michael VanSpall on December 5, 2018 11:13 PM

    No, they are not, these are pressed metal keys. 

  5. A No this lock does not have the ability to have readable audits. You will need an access control system to complete this function.

    While the 212SE is an excellent keypad for the requirements that you need the 212R will be better suited to your request. However, for both of them -20F is the lowest operational temp before it begins to be adversely affected by the cold. While it does not ruin the keypad it will cause it to slow in the response time the colder it gets and possibly even shut it down depending on the the cold and length of time exposed. To help combat any additional issues that would compound the cold such as rain or ice a weather guard is recommended.
