Introduction

The EC / EN Telephone Entry & Access Control System is designed for use as a primary access control device for gated communities, parking

garages, ofce buildings, apartments, dormitories, hotels/motels, commercial buildings, and recreational facilities.

NOTE: Minor variations exist between models utilizing different housing material which does not affect functionality. This manual references
the EN-2M4, but covers common functionality throughout the series and notes differences where applicable.

Housed in a locked enclosure, EC / EN Series units feature a back-lit keypad with bright, easy-to-read graphics, a color LCD directory display with
programmable welcome message, a built-in microphone and speaker, and an ADA compliant TTY jack for use by the hearing impaired. The system
also has provisions to internally mount a card reader, and for mounting a U.S.P.S. supplied postal lock. The cabinet security is monitored with a
mechanical “tamper” switch. The unit houses four relays. Two can be programmed to control electric door strikes, magnetic locks, door & gate
operators or barrier gates. The other two can be programmed for auxiliary options, such as a propped door alarm.

The system utilizes hands-free, telephone communications between visitors and residents for granting access. Complete access control event
logging, access time restriction, access location restriction, and administration functions are also available to manage the installation.

The EC Series is network ready, but it can’t interconnect to other EC / EN or EXN modules. The EN Model can be interconnected (one database)
to a controlling LAN hub via an Ethernet cable. Each EN Series unit can be used in mixed networks with other compatible access control products,
including the EN-2M4 (4.3” screen and key pad), EN-2M7 (7” touch screen and key pad). Refer to the Feature Overview section, next page.

Future Option - Four Wiegand reader inputs 2 doors In/out are available for connection of up to 64-bit format Wiegand devices (card readers, etc.).
Each reader input supports connecting an “in” and an “out” reader.

Operation

In a typical installation, the unit’s memory can be programmed with each resident’s name and directory code number. Arriving visitors would use the
keypad on the unit to view the directory names and directory number for the desired resident. Upon selecting the directory number, the unit will dial
the resident’s telephone number and establish two-way voice communication between the visitor and the resident. The resident will then have the
option to grant or deny access to the visitor by pressing the phone’s 9 key.

In addition to the telephone entry, the unit can grant access using entry codes at the local or remote keypads. Also remote receivers, card readers,
and interior and exterior keypads can be used with the system.

MegaCode® transmitters can be used to gain access through the included radio receiver. Each transmitter can be individually suspended or
re-activated. The system’s clock/calendar can control access based on specic times and dates. Automatic relay activation can be scheduled. Access
can be restricted to certain times and dates. Holiday access can be scheduled. The system’s event log records system activity for future reference.

Programming and Cardholder Maintenance

System programing and maintenance can be performed locally or remotely via a network LAN and/or WAN connection to the system.

Feature Overview

Relay Outputs

Two 3-amp dry contact Form-C SPDT relay outputs are provided to activate

access devices, such as door strikes, magnetic locks, automatic doors,

barrier gates, and automatic sliding gates. Two Auxiliary outputs can also be
used as specialty outputs for alarm contact shunting and alarm activation.
Each of the relays can also be manually activated from buttons on the unit’s
interface circuit board. These buttons also provide manual override to allow
doors/gates to remain open (Construction Mode) when necessary. LED
indicators display the status of each relay.

Request-to-Exit (REX) Inputs

Each door lock relay channel has a request-to-exit input. These inputs
are supplied for hard wire activation of the access devices. Typically a
request-to-exit input is wired to a pushbutton inside of the access controlled
area. When a person desires to exit, pressing the pushbutton will activate
the output relay channel and trigger the access device. A loop detector for
automatic gate operation can be connected to a request-to-exit input. The
inputs are also selectable NO, NC and/or supervised.

Door Switch Monitor (DSM) Inputs

The door switch monitor inputs connect to door switches that monitor
whether the controlled door is open or closed. As an option, REX can be
electronically over-ridden in the software.

Wiegand Reader Support

The unit’s four Wiegand inputs (READER #1 & READER #2) can connect
to Wiegand output accessories capable of reading up to 64 bit formats.
The system offers a Wiegand code decoder and most formats are offered
and can be congured to use existing credentials. The Wiegand format is a
common standard for access control equipment. A typical application would
be to add swipe card or proximity readers to the system.

Local Keypad

The local keypad is the system’s primary keypad. The local keypad activates
Door Lock Relay “A”, but can be programmed for any of the relays.

Postal Lock

The unit’s cabinet has provisions for installing a U.S.P.S. postal lock for
keyed mail carrier access. The postal lock will activate Door Lock Relay “A”,
but can be programmed for any of the relays. This feature also allows for
Access Levels to be applied for added security.

Removable Programming Memory

The unit’s removable 8GB SD card memory retains all entry codes,
transmitter information, user event data, card access, and programming.

Power Management

The unit is a 11-13 VDC system with minimum power of 1amp, (ISD is
powered with a 12 VDC PIP) and can be powered with a plug-in power
supply, or by using the Power Distribution Module (PDM). If an AC power
failure occurs, the Power Distribution Module (optional-not included) will
notify the system.

Network Support

Multiple EN-2M4, EN-2M7 and EXN units can be networked together via
individual Ethernet cables connected to a network. A common event log
is retained for all of the networked units. For redundant system backup, a
computer connected through the network can store and retrieve the memory
data.

Unit Access

Each EC / EN Series unit has a three-point locking mechanism with a
weather-tight male and female gasket designed door requiring 6 pounds of
pressure to securely close and open. When opening the cabinet, the primary
hinge is more exible than a solid continuous hinge. This design eliminates
requirements for special hardware or single purpose housings, allowing the
EC / EN Series unit multiple surface and ush mount variations.

Mounting Requirements for EC / EN Series Units

The EC / EN Series Telephone Entry & Access Control System can be installed for public or private use. The mounting requirements will vary
depending on the installation. Review the following information before beginning the installation.

Mounting Environment

Consider the environmental factors at the desired mounting location. The unit is designed for direct
outdoor installations, however, it is preferable to protect the unit from extreme exposure to sun, driving
rain, or snow whenever possible. Mounting the unit in a kiosk can provide extra environmental protection.

Mounting Surface

When mounting to an uneven surface use be sure not to bolt down the housing too hard. Shims
should be used to offset the uneven surface to ensure the housing is not warped when mounted.

Add
Shim

Follow Building Codes

Check all local, state, and national building codes and ordinances prior to installing the system. Proper
installation of the unit conforming to the local building codes for access control equipment is a regulatory
requirement. The unit’s installation is an extremely important and integral part of the overall access control
system. It is not designed to have direct water from drainage or water ow from roof on or behind the unit.

Mounting Location

If the unit is used to control a door or pedestrian gate, locate the unit as near as practical to the entry
point. If the unit is mounted on or in a wall adjacent to the entry point, be sure the wall is sturdy. The
repeated shock and vibration from a slamming access door or spring-loaded pedestrian gate must be
isolated from the unit. Avoid drainage spouts or areas where water runs directly down wall. NEVER
MOUNT THE UNIT DIRECTLY TO A MOVING DOOR OR GATE!

Gate Installations

If the unit is used to control a gate operator connected to a vehicular gate, the unit
MUST be mounted AT LEAST 10 feet away from the gate (open and closed) and gate
operator. AT NO TIME SHOULD A PERSON BE ABLE TO TOUCH THE GATE OR
GATE OPERATOR AND THE UNIT AT THE SAME TIME.

Vehicle Trafc

Do not mount the unit where it extends into any trafc lane. Locate the gooseneck
pedestal or entry kiosk so all parts of the unit are outside the trafc lane. Locate
the unit clear of any turn-around lanes vehicles use when access is denied.

Americans with Disability Act (A.D.A.) Requirements

THE FOLLOWING WHEELCHAIR ACCESS REQUIREMENTS ARE FOR PUBLIC DOOR CONTROL INSTALLATIONS ONLY.

1. If the clear oor space allows only forward approach to the system,
the maximum high forward reach allowed is 48” above grade to the
top of the keypad.

2. If the high forward reach to the system is over an obstruction of
greater than 20” but less than 25”, the maximum high forward
reach allowed is 44” above grade to the top of the keypad.

3. If the clear oor space allows parallel approach by a person in a
wheelchair, the maximum high side reach shall be 54” above grade
to the top of the keypad.

4. If the high side reach is over an obstruction of 24” or less, the
maximum high side reach allowed is 46” above grade to the top of
the keypad.

Entry System Mounting

ACH

SURFACE

The unit’s cabinet is designed to be mounted two ways:

• The unit can be mounted directly to a wall or at
surface.

• The unit can be mounted on a standard
gooseneck pedestal.

Choose a well lit location near the controlled opening.
Wiring access for power, telephone, network, earth
ground, and control outputs must be available to the
mounting location. If the optional remote accessories
are used, wiring access for these cables must also be
available to the mounting location.

Surface Mounting

The cabinet can be mounted on a wall or any suitable
at surface. The four 3/8” mounting holes or the four
self-drill locations can be used to attach the cabinet to
the surface.

1. For wall mounting, hold the template at the
approximate mounting location where the display
will be about eye level or slightly above.

2. Remove the PCB Board to avoid metal shavings
affecting the PCB’s.

3. A) If using the 3/8” mounting holes, mark the four
mounting hole centers. Drill as required. Use the

appropriate fasteners for the mounting surface to
secure the cabinet.

B) If using the self-drill mounting holes, choose
the correct size bit for the fasteners and drill the
cabinet as required. Use the appropriate fasteners
and self-drilling or self-tapping screws for the
mounting surface to secure the cabinet.

C) Re-attach the PCB Board.

4. If the surface is uneven, be certain NOT to over

tighten the corners of the housing to avoid. Over
tightening could cause the housing to warp.

The use of a silicon seal is permitted along the

top and sides of the case where the unit meets
the mounting surface (ensure that the Weep holes
located along the bottom edge remain free of
silicon and debris). Ensure that water runoff from
building does not impact the unit.

Wiring - Best Practices

1. Terminals are in a separate bag. This allows the installer to pull through the cabinet ~12’ of cable and wire to the terminal not mounted to the

board.

2. Make sure the cable drops down in the housing prior to connecting to the PCB. This will allow for condensation to drip to the bottom of the
cabinet and not directly to the PCB boards.

3. Cabling for system ground always needs to be the correct cable type and gauge as dened for the system..

4. Be sure to use the transient protection where recommended.

5. The Entry series includes a power supply. It is not intended to power locking hardware or other devices.

Relay Wiring for Door or Pedestrian Gate Control

1. Door Lock Relays A & B can be used to control electromechanical access devices on doors. The door will unlock when a user is granted access

by the system. The door will remain locked if a user is denied access (see diagram, next page).

2. The door lock relay outputs can each be congured to operate in fail-secure or fail-safe modes.

3. In fail-secure mode, a door lock relay energizes when access is granted.

4. In fail-safe mode, a door lock relay de-energizes when access is granted.

12

Door Strike

1. Install a low voltage electric door strike as a locking device for the door or pedestrian gate.

2. Install the power supply or transformer for the locking device. DO NOT POWER THE UNIT FROM THIS POWER SUPPLY.

3. Connect one wire from the power supply to one wire from the locking device.

4. Route two wires between the locking device and the unit. Connect one wire to the remaining wire of the locking device. Connect the other wire

to the remaining wire of the power supply.

5. Install a protection diode (for DC door strikes) or MOV (for AC door strikes) across the strike to protect the door relay contacts.

6. Connect the wires to the unit’s DOOR LOCK RELAY COM & NO terminals for fail secure operation or DOOR LOCK RELAY COM & NC

terminals for fail safe operation.

Request-to-Exit (REX) Inputs

The two door relay outputs have REX input terminals. Grounding a REX terminal will request activation for the associated relay. Exit request inputs
are typically used with push bars, loop sensors, or pushbuttons.

1. Install the pushbutton or device to signal an exit request.

2. Route two wires from the device to the unit.

3. Connect the device’s normally open output to the wires.

4. Connect the two wires to the associated relay’s request-to-exit REX terminal and GND terminal.

5. Connecting the DSM Override allows the administrator portal monitoring without requiring the REX to automatically energize the lock output.

Auxiliary Inputs

The Auxiliary Inputs are general purpose inputs that can be used with a variety of input devices including REX switches, loop sensors, alarm system
integration, etc. These inputs can be congured via programming to trigger a dened action such as to activate an auxiliary relay output.

Tamper Protection

A tamper switch is mounted inside the enclosure and connects to terminals on the CPU board. If the cover or enclosure door is opened for any
reason the tamper switch will activate, triggering a condition that can be linked to an event action in programming (e.g., send an e-mail or generate
an output).

Wiegand Accessories

The unit’s four Wiegand inputs (WIEGAND #1 IN/OUT & WIEGAND #2 IN/OUT) can be connect to Wiegand output accessories capable of reading
up to 64 bit formats. The Wiegand format is a common standard for access control equipment. A typical application would be to add swipe card or
proximity readers to the system. Readers can be installed as primary “in readers” (entry) for each door as well as optional secondary “out readers”
(exit).

The maximum power available for an individual reader is 750 mA @ 11-13 VDC with a combined maximum of 1.5A for the unit. Determine the
reader’s power consumption by referring to the documentation included with the reader. Exceeding the maximum current for individual readers or for
the system will damage the protection fuses and void the warranty.

NOTE: Remove Excess Shield. Exposed Shield can cause interference or shorts. Tape off to make sure no shield is exposed.

NOTE: When using Wiegand devices for Reader

“B”, Reader “B” select jumper must be set to Wiegand
position (default).

1. Mount and install the Wiegand accessory as described in
its installation instructions.

2. Route the cable from the unit to the accessory.

Recommended cables:

• Belden 9535 (or 24AWG; 5 conductor; Shielded
Equivalent)

• Weico 8606/18 (or 18AWG; 6 conductor;
Shielded Equivalent)

3. Connect color-coded wires from reader’s wiring harness
to cable.

4. Connect the cable to the appropriate Wiegand READER
terminal on the unit (see Wiegand wiring diagram).

IMPORTANT: Reader shields must be properly
grounded per the manufacturers installation
requirements. See diagram for shield connections.

Telephone Wiring

For telephone entry applications, the unit connects two wire POTs and/or VOIP telephone lines: 24 and 48 volts.

Important Telephone Wiring Tips

• WIRING SHOULD BE PLACED IN SEPARATE JACKETED CABLES FOR TELEPHONE AND AC. Route all telephone wires inside a
dedicated conduit that is at least six inches away from any AC line wiring.

• All telephone wiring must be made on the “building” side of the telephone company’s demarcation device (the terminal block where the
telephone line connects to the building).

• If any security system or personal alert system at the installation is connected to the telephone line, be sure that it is connected to the line
ahead of the unit using a RJ-31X or RJ-38X interface.

• Use only high-quality telephone wire. All telephone wire should be twisted-pair with a minimum size of 24 AWG.

Typical Telephone Wiring

1. Connect a double-ended modular RJ-11 cable to the unit’s TELEPHONE jack.

2. Connect the RJ-11 modular cable to the telephone jack wired to the installation’s telephone line.

STEP 2: Network Installation Options / Connections

An access control network allows shared programming and user information between systems. Networks make system programming and facility
management much easier in multi-unit installations.

The EC / EN Series Telephone Entry & Access Control System is designed to be compatible with each other when residing in a multi-unit network
operating environment.

IMPORTANT COMPATIBILITY NOTE: The legacy Linear access control Models AE-1000, AE1000Plus, AE-2000, AE2000Plus, AM3, and
AM3Plus are of a different hardware and software design and CANNOT be used in networks mixed with the new generation Models EN-2M4,
EN-2M7 and EXN.

Local Area Network

In installations where there is an existing LAN / WAN or TCIP Network connector used for interconnecting various computers and peripherals to the
Internet, the unit’s LAN / WAN or TCIP is sufcient for connecting the system. The unit will need to be congured with the correct network settings
before connecting to the network (see the Conguring for a Local Network section, pg. 24).

CAUTION: DO NOT connect to the LAN / WAN or TCIP Port until the system is congured.

If the unit is going to be connected to a LAN / WAN or TCIP Network, it must be located in a trusted network environment where a protected network
security system (rewall, etc.) is installed and maintained.

Prepare the system for connection to the LAN / WAN or TCIP Network by running the networking cable between the unit and the network router. Wait
until further conguration of the system’s network settings (see the see the Conguring for a Local Network section, pg. 24) before actually plugging
in the network cable into the LAN / WAN or TCIP Port of the unit.

1. Find the location of the Local Area Network router that will serve the EC / EN Series system.

2. Select a networking cable long enough to run from the LAN / WAN or TCIP Network router to the specic unit being connected.

3. Route the networking cable into the unit’s enclosure and bring it close to the LAN / WAN or TCIP PORT jack. DO NOT PLUG THE CABLE IN YET.

NOTE: For ETL installations, the maximum networking cable length allowed is 30m (98.5 FT). For applications requiring longer distance consult
factory for network extender.

Congure all (if any other) units in the network following the preceding steps.

STEP 3: Ethernet LAN Connection

The EC / EN Series Telephone Entry & Access Control System connects to a controlling LAN via an Ethernet connection on the CPU. Previous
Telephone Entry Systems utilized the RS-485 cable connection via a “daisy-chain” to connect multiple units. This type of connection is obsolete and
current EC / EN Series units do not require linked type connections to communicate with the LAN. If this is a retrot and only two wires exist between
hardware, NSC offers a 2 wire to TCIP convert. Consult your local rep or support for more information.

Ethernet Wiring connection with CPU

1. Mount and install the units for the network.

2. Route Ethernet networking cable through back of unit.

3. Connect Ethernet cable to the LAN connection point on the CPU.

STEP 4: Conguring for a Local Area Network

The unit must be located in a trusted network environment where a protected network security system (rewall, etc.) is installed and maintained.

CAUTION: The system is exposed to potential risks if installed on a network without proper security precautions. Consult the appropriate on-site
IT administrator.

Obtain the following information from your network administrator before conguring the e3 Controller:

• IP address: ____________________________________

• Subnet Mask: ____________________________________

• Gateway: ____________________________________

• DNS 1 and 2: ____________________________________

NOTE: If a DHCP server is present, IP Addresses are dynamically assigned. A static IP address is strongly recommended for the EN-2M4
because a DHCP Server may assign a new IP Address. There may be times when you want to access the product directly.

Preparing for the Network

To allow for the system to be recognized on the local network, it is necessary to change the unit’s IP address as follows:

1. Connect your programming computer directly to the LAN port of the unit. A standard networking cable is used for the direct connection.

2. Assign a static IP address of 192.168.0.149 to the computer. (For instructions on how to change the static IP address of a Windows computer,

please visit: http://technet.microsoft.com/en-us/library/ff710457).

3. After assigning the static IP address for the computer, open a web browser and enter the IP address of the unit (Default = 192.168.0.250). The
static IP address will allow uninterrupted data transfer between devices.

4. The unit presents the login page. To log on, enter the default user ID and password (admin/admin).

5. Select the Network Setting icon, then the IP Address icon to display the page. Enter the static IP address, Subnet Mask, Gateway and DNS

server so that it matches the requirements of the local network. (Refer to the unit Programming Guide for detailed programming information.)

6. Click Save & Reboot and the system will reboot. (Reboot will take approximately 2 minutes.)

NOTE: The system data will be lost if the unit is powered down without performing Save & Reboot.

7. Disconnect the programming computer from the unit. The system is now ready for the local network.

8. Connect the networking cable from the Local Area Network to the unit’s LAN PORT jack. The local computers will then be able to access the

system by entering the IP address of the unit.

9. Connect the cable to the CPU board.
