Linear Linear Single Door Controllers

Linear's single door controller entry systems are an excellent way to control access at a single entry point.

Common Features

Up to 480 programmable input codes.
4 independent outputs with programmable actions, activation times.
Dual color LED indicators for access, lockout, and programming status.
Tactile feedback ensures complete key presses.
Internal sounder with selectable volume levels.

Up to 480 codes (1 to 6 digits each) can be programmed via any Linear keypad without need for a separate programmer. Each can activate either or both relay outputs.Timed anti-passback prevents use of the same code again before time elapses.

SENSE input: If programmed for “door sense,” input is wired to a normally closed switch to detect when door is open or closed. Forced entry or door ajar situations can be detected. If programmed for “inhibit,” input can be wired to service switch or timer to disable main relay.

REQUEST-TO-EXIT input: Can be wired to a pushbutton for codeless activation of main relay, auxiliary relay, output 3, or output 4.

ALARM shunt:Activates when access is granted. It can be wired to shunt alarm contacts on the access door/gate to prevent alarming when access is authorized.

Other programmable features include: system reset key(s); entry code length; adding a PIN; erasing any or all PINs; changing master code; on-time for each output; keypad lockout upon incorrect PINs; and anti-passback time period (or no anti-passback). EEPROM memory retains all entry codes and programming, even without power.

AK-3 Low-cost Interior Digital Keypad (ACP00903)

Linear AK-3 Low-cost Interior Digital Keypad (ACP00903)

The Model AK-3 Low-cost Interior Digital Keypad is a digital keyless entry system designed for access control applications. The keypad is housed in a rugged, plastic enclosure and is designed to be mounted in a standard single-gang electrical box. The die-cast keys have bright, easy-to-read yellow graphics.

Up to 480 entry codes, from 1 to 6 digits in length, can be programmed. They can activate either, or both, of the relay outputs. The anti-passback feature prevents using the same code again before the programmed time elapses.

Two indicators show the status of the entry system. The left indicator lights red to indicate power, then turns green when access is granted. The right indicator lights yellow when the keypad is in lockout condition (from too many incorrect code entries). An internal sounder beeps when each key is pressed. An internal jumper sets the sounder volume high or low.

Features

Self-contained keyless entry system ideal for airports, hospitals, warehouses, office buildings, parking lots, and many other commercial facilities
Mounts in a single gang electrical box
Four independent outputs and timers: two form C relays and two solid-state open collector outputs
Up to 480 programmable input codes of one to six digits each for activating either or both relays

Key operating features include: door sense input; inhibit input; request-to-exit input; alarm shunt output; timed anti-passback; and keypad lockout
Rugged metal keys
Tactile and audible feedback
3" W x 5" H x 3" D
