Rugged Access Keypad for Secure Entry
The Linear 212R is a surface-mount keypad built for indoor or outdoor access control. Its cast aluminum housing and metal faceplate resist weather and tampering. The unit supports up to 120 user codes on a 12-button layout with metal Braille markings. It operates on 12 to 24V AC/DC with auto-adjusting input.
Sustained Operation in Harsh Conditions
The keypad functions continuously across a temperature range of 20 to 130 degrees Fahrenheit. Four SPDT relays rated at 5A AC, Form C at 24V DC, handle repeated switching without an event audit trail. The painted gray finish protects the cast aluminum from corrosion during long-term exposure. No cylinder is included for mechanical override.
Verify Voltage and Mounting Before Ordering
Confirm your power supply delivers 12 to 24V AC or DC to match the auto-adjusting input. Ensure the mounting surface accommodates a 3 3/4 inch width by 5 1/4 inch height footprint with 2 1/2 inch depth. The stand-alone design requires no external controller, but wiring must support the relay output specifications.

It accepts 12 to 24V AC/DC auto-adjusting and each of the four SPDT relays is rated at 5A AC, Form C at 24V DC.
What separate power source must I already have to operate this keypad?
You need a 12 to 24V AC/DC supply; the keypad auto-adjusts within that range.
Will the 120 user codes I program into the Linear 212R still work if I keep my older 12V access controller?
Yes, the keypad operates from 12 to 24V AC/DC, so a 12V system is within its input range.
