Linear  AM3Plus  4-Portal Access Controller - ALSO LISTED AS #ACP00950 Linear A2C/DB25 Serial Port Cable


Product Number: ACP00950

The Model AM3Plus 4-Portal Access Controller is designed for use as a primary access control device for gated communities, parking garages, office buildings, apartments, dormitories, hotels/motels, commercial buildings and recreational facilities.

Housed in a lockable, plastic enclosure, the AM3Plus features a 2-digit LED display, nine status indicators, four relay indicators with four relay activation pushbuttons. Three programming buttons, a reset button, and a power indicator are present. The enclosure is monitored with a magnetic tamper switch.

The system controls its four output relays by responding to various input devices that react to proximity cards, transmitters, and entry codes. The four relay output channels can be programmed to control electric door strikes, magnetic locks, door & gate operators, or barrier gates.

Access is granted or denied depending on the current users authorization to gain access and system settings that control groups of users or all users. Complete access control event logging, access time restriction, access location restriction, and administration functions are also available to manage the installation.

For easy programming, the AM3Plus contains Linear's built-in browser-based AXNET software. The system can be programmed and maintained from any computer world-wide, without using dedicated computer software. The AM3Plus is also compatible with Linears powerful AccessBase2000 dedicated access control PC software.

The AM3Plus is network ready. AM3Plus units can be interconnected with Linears AE1000Plus and AE2000Plus Telephone Entry Systems through a 3-wire RS-485 or modem network. The AM3Plus can be used in networks with the legacy AM-3, AE-1000, and AE-2000 Telephone Entry Systems in installations programmed with AccessBase2000 software only.

Two sets of Wiegand inputs are available for connection to 26, 30, or 31-bit Wiegand devices (card readers, etc.). Two sets of PBUS inputs are available for connection to Linears line of remote accessories.

  • Linear AM-RPR Remote Proximity Receiver Linear AM-RRR Remote Radio Receiver
    Product Number: ACP00560

    The Model AM-RPR Remote Proximity Receiver is designed for use with Linear's access control systems. The AM-RPR functions as a remote device that supplies localized radio reception.

    In a typical installation, the AM-RPR would be mounted in a plastic single-gang electrical box next to the controlled opening. When the user requires access, their transmitter must be activated within three inches of the AM-RPR faceplate. The ultra-short range of the AM-RPR allows placement of a unit by each controlled opening without the possibility of the transmitter being detected by the wrong receiver.

    A two-color indicator on the AM-RPR faceplate displays the receiver's status. The indicator lights red when the receiver is getting DC power from the system and turns green when access is granted to a transmitter.

    • Convenient, cost-effective, and reliable form of door or entrance control
    • 2-to-3-inch radio transmitter read range
    • Compatible with Linear radio-based access control systems
    • 2-color status LED indicates "power on" and "access granted"
    • Installs in a single-gang electrical box
    • Prevents transmitter from being detected by wrong receiver
    • 2.7" W x 4.5" H x 2" D
    Product Number: ACP00500

    The Model AM-RRR Remote Radio Receiver is designed for use with Linear's access control systems. The AM-RRR functions as a remote device that extends the radio range or supplies localized radio reception.

    Three antenna types can be used with this receiver. The cabinet mounted type F connector is for connection to the antenna. The local whip antenna (supplied) screws directly on to the receiver's connector. The directional (EXA-2000) and omni-directional (EXA-1000) remote antennas wire to the receiver's antenna connector with type RG-59 cable.

    An on-board RADIO RANGE knob allows adjustment of the receiver's gain. It can be set to limit the maximum radio range that the receiver can achieve. Two indicators display the receivers performance and operation. The two color red/green STATUS indicator lights red when the receiver is getting DC power and turns green when access is granted to a transmitter. The RADIO indicator lights when the receiver detects a radio signal. It can be used for trouble shooting and verifying system performance. Receiver test points are provided for listening to the incoming signals.

    The receiver is housed in a weather-resistant enclosure and can be mounted indoors or outdoors. Gaskets and a weather-tight wiring strain relief seal the unit from the elements.
