Linear AKR-1 Keypad With Radio Receiver
The Model AKR-1 Exterior Digital Keypad with Radio Receiver is a digital keyless entry system designed for access control applications. The keypad is housed in a rugged cast aluminum enclosure that can be mounted to a pedestal or bolted directly to a wall. 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.
Up to four sets of block coded MegaCode® transmitters (up to 480 transmitters total) can be used to gain access through the AKR-1's built-in radio receiver. Each transmitter can be individually suspended or re-activated. Four facility codes can be programmed to identify each block of transmitters. A Radio Test Mode is provided for testing transmitters and detecting radio interference. Programming of individual (non-block coded) transmitters is not supported by the AKR-1.
Linear's Model MGT safety edge transmitter is compatible with the AKR-1. This supervised transmitter is used to detect and transmit obstacle events to the AKR-1 receiver. Obstacle signals from an MGT transmitter will activate Relay #2.
Self-contained keyless entry system ideal for airports, hospitals, warehouses, office buildings, parking lots, and many other commercial facilities
Rugged, cast aluminum enclosure for indoor or outdoor mounting on a wall or pedestal
Built-in radio receiver
Four independent outputs and timers: two form C relays and two solid-state open collector outputs
Accepts 480 entry codes, 480 block code transmitters, plus one fully supervised Model MGT safety edge transmitter
Two LED indicators show system status
Key operating features include: door sense input; inhibit input; request-to-exit input; alarm shunt output; timed anti-passback; and keypad lockout
Down light illuminates whenever keypad is used
Tactile and audible feedback
Keylock secures keypad to mounting backplate
RF frequency: 318 MHz
4" W x 7" H x 3" D
Order number: ACP00747

Wired Keypads
wired keypads are the most common type. Most of them can open a gate momentarily or hold it open. They range in code capacity from 3 codes to thousands. Almost all of them have an illuminated face for operating in darkness. The higher end ones have two independent sets of contacts to control 2 gates or doors. The commercial grade units are made with Stainless steel fronts and heavy gauge steel powder coated cases.
Solar Keypads
Solar ready keypads are also an available option. These units draw very little power and generally have an LED to light the front panel.
Wireless Keypads
Wireless keypads are a limited alternative. These units work on a 9 volt battery, and cannot do a hold gate open function. The inexpensive units have only one access code. They have a light on the face that is not normally on, and activates after one of the keys is pressed. These units should always be mounted on non metal surfaces. Metal drastically reduces the operating range to render the unit virtually non-operational. The Linear AKR-1 keypad is an exception to this rule because it has a top mounted antenna. An inexpensive wireless keypad is useful as an adjunct to a wired keypad placed inside the gate.
