Linear Entry Pro Series Installation Manual

Introduction

The Linear Entry Pro (EP) Telephone Entry & Access Control System is designed as a primary access control device for various locations including gated communities, parking garages, office buildings, apartments, dormitories, hotels/motels, commercial buildings, and recreational facilities. It offers advantages over older RS485 systems by enabling shared programming, user information, remote accessibility, and enhanced scalability for complex installations. The unit features a stainless-steel, back-lit keypad, a 4.3” color LCD directory display or a 7” touch screen, a built-in microphone and speaker, and an ADA-compliant TTY jack. It also supports an internally mounted card reader and a U.S.P.S. postal lock. Security is monitored via a mechanical tamper switch. The system includes four relays: two for controlling door strikes, magnetic locks, gate operators, or barrier gates, and two for auxiliary functions like propped door alarms. It facilitates telephone communication for granting access and logs all access control events, time restrictions, and administrative functions. EP-xx2 models are standalone but can interconnect with EP-x36 and EXN modules for larger installations, sharing a common database. For networked multi-system installations, only one unit should act as the server; others can be configured as clients.

Operation: In a typical setup, residents are programmed with names and directory codes. Visitors use the keypad to find residents, and the system dials their phone number for two-way communication. Residents can grant access by pressing '9' on their phone or deny by ending the call. Access can also be granted via entry codes, remote receivers, card readers, and keypads. MegaCode® remote transmitters can also be used. The system's clock/calendar can manage access based on schedules, including holidays. Event logs record system activity.

Programming and Cardholder Maintenance: Performed locally or remotely over a network connection after initial configuration.

Recommended Wiring Requirements: Power cables must be appropriately gauged for the load and routed separately from high voltage or AC wiring. The table provides recommended wire gauges (AWG) and maximum distances for various amperage loads (0.5A, 1.00A, 2.00A) at 12VDC and 24VDC.

Wiring - Best Practices: Terminals are provided separately. Ensure cables drop down into the housing to prevent condensation on PCBs. Use correct cable type and gauge for system ground. Use transient protection where recommended. The unit's power supply is for the unit only, not for locking hardware.

Relay Wiring for Door or Pedestrian Gate Control: Door Lock Relays A & B control access devices. They can be configured for fail-secure (energizes on access granted) or fail-safe (de-energizes on access granted) modes.

Door Strike Wiring

DC Door Strike Wiring:

• Fail Secure: Door lock relay energizes when access is granted. Door unlocks when strike is energized. Requires a diode (e.g., 1N4933) and Transorb SA48C for protection.
• Fail Safe: Door lock relay de-energizes when access is granted. Door unlocks when strike is de-energized. Requires a diode and Transorb SA48C.

AC Door Strike Wiring:

• Fail Secure: Door lock relay energizes when access is granted. Door unlocks when strike is energized. Requires MOV (e.g., SNR-D56K2) and Transorb SA48C.

Note: Do not power the unit from the strike's power supply. Install protection diodes/MOVs across the strike.

Mag Lock Wiring

DC Mag Lock Wiring:

• Fail Secure: Door lock relay energizes when access is granted. Door unlocks when mag lock is de-energized. Requires a diode (e.g., 1N4002) and Transorb SA48C. Power supply must have battery backup.
• Fail Safe: Door lock relay de-energizes when access is granted. Door unlocks when mag lock is de-energized. Requires a diode and Transorb SA48C.

Note: For fail-secure mag locks, battery backup is essential. Comply with NFPA and local building codes.

System Input Wiring

The system uses three types of switch inputs: Door Position (DSM), Request-to-Exit (REX), and Auxiliary. Inputs can be configured for normally open (NO) or normally closed (NC) contacts, with or without supervision. 1k ohm resistors are used for supervision.

Input Options:

• Supervised Input: Shorting or cutting wires signals a trouble condition. Requires a 1k ohm resistor.
• Unsupervised Input: Shorting or cutting wires does not signal a trouble condition.

Door Switch Monitor (DSM) Inputs: Connect to door switches to monitor door status. Typically uses magnetic contacts or mechanical switches. Wires connect to DSM and GND terminals. If the contact is normally closed, program the input accordingly.

Diagram Description (DSM = DOOR SWITCH MONITOR INPUT): Shows a DOOR POSITION CONTACT connected to DOOR "A" OR "B" DSM TERMINALS via GND and DSM lines.

Request-to-Exit (REX) Inputs

Grounding a REX terminal requests relay activation. REX inputs are used with push bars, loop sensors, or pushbuttons. Connect the device's normally open output to the REX and GND terminals. DSM Override can be used for monitoring without automatic lock activation.

Auxiliary Inputs: General purpose inputs for REX switches, loop sensors, alarm systems, etc. Can be configured to trigger specific actions or auxiliary relay outputs.

Tamper Protection: A tamper switch inside the enclosure detects front panel opening and can trigger programmed actions, such as sending an email.

STEP 2: IP Address Configuration

Before connecting the EP unit to the Local Area Network (LAN), initial IP configuration must be completed by directly connecting a Laptop/PC to the EP unit's LAN port using a CAT5 cable. Telephone entry systems require a static IP address, not DHCP.

Configure IP Network Settings:

1. Connect programming computer to EP unit's LAN port.
2. Assign a static IP address (e.g., 192.168.0.149) to the computer.
3. Open a web browser and enter the unit's default IP address (e.g., 192.168.0.250).
4. Log in using default credentials (User ID: admin, Password: admin). It is highly recommended to change the default password.
5. Navigate to Network Setting > IP Address to configure IP Type (Static), IP Address, Subnet Mask, Gateway, and DNS servers as provided by the IT administrator.
6. Click "Save & Reboot" to apply settings (reboot takes approx. 2 minutes). IP settings are lost if power is lost before saving.
7. Disconnect the programming computer.
8. Connect the unit to the LAN via its RJ45 port.

Caution: The EP system should reside on an isolated or segmented security network with a firewall. Avoid port forwarding for remote internet access; use a VPN.
