Step 3: Access Control Overview
Step 3: Access Control Overview
Electronic access control has revolutionized the world of locksmiths and security. The safety in one’s
surroundings is essential. With electronic access control, where keys are replaced by electronic cards, a
person’s access to his/her place of employment/residence can be monitored and controlled. Strangers or
guests are limited in their access to a complex and workers or residents can feel safe in knowing that their
possessions and work environment are safe from those outside their office or home.
ACCESS CONTROL POINTS
An access control point is usually a door where a person’s access is controlled by time, duration and
privilege. Is this person allowed to enter this door? At what time(s) of the day and week is this person
allowed in or out? How long is this person allowed in through this door before s/he has to come out?
Each EMC can have (2) two access control points per panel, or (2) two doors. Additional units
added to the first then increase the number of doors one unit can control and monitor. With two
EMCs hooked together, one can monitor four doors; with three EMCs hooked together, one can
monitor six doors, and so on.
An access control environment can vary by the number of units in a system and the number of doors
that can be monitored. Likewise, the equipment or elements in an access control point may vary due
to the level of security needed or the kind of access allowed.
HOW THE SYSTEM WORKS
On the system level, the EM3000 software runs the access control system by communicating
instructions from the computer through an RS-485 communications converter to the EMC.
The EMC uses card readers as the access control device to gain entry. Each EMC will manage two
readers and the accompanying door sense equipment. Door locks, usually door strikes or magnetic
locks, must be powered by a separate low voltage power supply other than that powering the EMC
and readers. There is often a door monitoring contact that is used to monitor if the door is closed or
open.
Other types of equipment that can be used include:
A REX (Request To Exit) device: A push button that releases the door lock to allow one to
exit through the door.
A PIR (Passive Infrared Detector): A detector that has the same function as a REX, but is
activated by body temperature. These are important if monitoring the door for alarm activity is
used. The REX equipment bypasses the alarm detection software for a period of time to allow
free exit. If the REX equipment is not used, and the door is being monitored for alarms, an
alarm will be generated every time someone leaves through the door.

Determining Your Needs
Start by deciding the kind of installation you need. Some sites require a tremendously enhanced level of
access control, coupled with a security staff. However, most systems require only a fraction of that
amount. Which kind of access control system do you need?
Start with a detailed description of what your system needs to accomplish. Every site will differ because of
the different objectives and requirements. Some examples are:
A store needs to limit shoplifters from leaving through unauthorized exits and to maintain control of
the delivery areas, stock rooms, and the store when it’s closed.
An office building needs to monitor when employees enter and leave departments, to inhibit
entrance by unauthorized people, and to control exits.
An institution or hospital requires that individuals stay in certain areas and out of other ones during
normal operation, but then have the ability to exit the site in case of emergencies.
These are just a few examples. Know what each particular site will require and the level of control that will
be required.
Planning Your Site
A detailed plan of your site is probably the most important element of installing a system in a matter of
hours versus a matter of days. Before proceeding, be aware of the necessities and limitations of different
parts of the system.

Step 3: Access Control Overview
SYSTEM SETUP REQUIREMENTS
In every case, an access control system will require the set up and placement of the following:
EMC with its 12VDC Power Supply Board connected to a 110VAC junction box
Personal Computer that monitors the access control system
At the access control point, a Reader that determines access and a functional Electronic
Door Lock (with its own dedicated power supply) that allows access through the access point
Note: If your site must be fully functional during a power failure, door locks must have their
own battery back-up.
EMC
The proper placement of the EMC is the most
important decision in planning your installation.
Find a location that is dry, safe from large
temperature variations, and most importantly,
secure from the unexpected (e.g., vandalism).
The recommended installation locations are:
1. Telephone/ PBX rooms
2. Computer rooms
3. A wall near one of the Readers (protected
area)
4. Above a false ceiling
The EMC is rated for indoor installation only.
To keep your EMC working properly, place where:
the temperature range is between 45-135 F (non-condensing).
maximum distance from reader(s) to EMC is 500 feet.
maximum cable distance from the PC (at the RS-485 converter) to the last EMC (if you are
using more than one) is 4,000 ft. If your installation absolutely requires a longer distance, use
an RS-485 repeater (such as B&B Electronics-485OP) to amplify the signal. Refer to the
repeater’s installation instructions for more information.
You should select an area that is the most convenient for cabling and future maintenance.
Figure 3: EMC
Doc 6001536, Rev C
Readers
Readers should always be less than 500 feet
from the EMC.
Sentex recommends that you place your reader
between 36-48” (90cm-120cm) from the floor,
though installation should conform to the local, city,
county and state installation codes.
Step 3: Access Control Overview 9
Figure 4: Reader Installation
Door Strike, Door Status Sensors, PIRs and REXs
Like the reader and the door lock, the door status
sensor and REX must be positioned within 500 feet of
EMC. The door sense is most often placed at the top of the
door in order to “sense” the position of the door (open,
closed, forced).
The PIR or the REX are placed on the opposite side of the
wall and allows people to exit the room or hall. The PIR is
used for automatic exit procedures or motion-detectors,
while the REX is used for manual exits.
SUPERVISED DOOR SENSE AND REX INPUTS
Sentex Systems recommends installing “supervised”
Door Sense and REX inputs. Supervised inputs allow
the system to monitor when Door Sense or REX wires
have been shorted or cut (see also Reading the Ten-
Segment LED Array on page 24).
For installing supervised Door Sense and REX
inputs, refer to Figure 12 (page 16) and Figure
13 (page 17).

Step 4: Installation of the EM3000 System
Step 4: Installation of the EM3000 System
Before you begin, review the safety guidelines that follow. Installation of your system should take
approximately 1-3 hours per access control point (depending on your familiarity).
Grounding
The EM3000 contains parts that may be damaged by static discharge. A proper earth ground connection
will significantly reduce the chances of damage or improper operation.
Damage caused by static discharge is not covered by warranty.
To be effective, the ground connection must be
made by running 12 AWG shielded copper wire to a
good ground point (e.g., an electrical panel, a
metallic cold water pipe that runs into the earth, or
a grounding rod at least 10 feet in length that is
driven into the earth) within 12 feet of the unit.
Ground all shield/drain wires (except RS-485
cables) at the earth ground screw, located within
the EMC cabinet (see Figure 6). Ground
shield/drain wire of RS-485 cable at the PC (using
a case screw).
Even if you have a good earth ground, you should
try to discharge any static before handling the
circuit boards.
Tips to Ground Yourself
1. Use a grounding strap.
2. Touch a metallic, cold water pipe that runs into the earth.
PROPERLY ROUTING THE CABLES
Do not route data and power cables in the same conduit. Cross-talk and transmission of electrical
noise may result. The EMC’s printed circuit boards will become damaged if the power cable grounds
to the data cable.

Step 4: Installation of the EM3000 System 11
GROUNDING THE 110 VAC POWER LINES
All high voltage grounding and wiring should comply with local, state, and federal regulations, as well
as conform to NEC standards. In general, use a third green wire ground with 110 VAC power runs.
Ground wire should be appropriately connected to source ground, as well as junction boxes, backboxes, and enclosures.
GROUNDING READER AND DOOR HARDWARE CABLES
Ground the shield/drain wires from readers, door strikes, door status sensors, and REXs at the earth
ground screw, located within the EMC cabinet (see Figure 6).
Procedure:
1. All cables from readers, door strikes, door status sensors, and REXs must be properly earth
grounded to ensure stable operation. Use the “Open-ended grounding” technique. This
technique means to tape back, or isolate, one end of the shield drain wire and earth ground
the other. An example would be to tape back the shield at the reader side and to tie the
shield at the EMC side to earth ground (see Figure 10). Please be aware that operation is
affected by the amount of static present during certain times of the year.
2. At the reader site, it is important to be aware of both the static generated from electrical
grounding from the data and reader cabling, as well as the user site. If at all possible, the
reader mounting plate should be attached to a grounded junction box or to another grounded
source, if the junction box is non-metallic. This alleviates the possible damage caused by
static electricity.
3. If grounding locally is not possible, connect drain wires to provided ESD (Electro Static
Discharge) hardware at the unit site (enclosure) or to an earth-grounded conduit. As each
reader port is progressively farther away from the ESD hardware location, allow for enough
drain line to reach the ESD hardware on the EMC end of the cable. Allow enough strain relief
to avoid touching other circuitry or creating excessive tension.
GROUNDING THE RS-485 COMMUNICATIONS CONNECTION
The cable connecting the RS-485 converter (at the PC) to the EMC must have its shield/drain wire
grounded to the host PC (at case screw). The other end of the cable’s shield/drain wire must be
attached to the EMC board (at SHIELD). For more information, refer to Connecting the RS-485
Converter (EMC to PC Communication) on page 20.

Noise Suppression
Sentex has designed its products to withstand most inductive voltage spikes without affect. However,
some noise found in power supplies and door strikes, in addition to static discharge, may cause the control
unit to momentarily shut down, lock up, or in extreme cases, become damaged. Unexplained lockups and
intermittent system behavior are common symptoms of static or noise problems. If cycling power will
remedy your problem, carefully follow these instructions:
1. For DC powered door strikes, install a
)
K
diode (IN4004 or equivalent) at the
strike with the positive DC power
connected to the cathode (K), or
banded, end of the diode (see Figure 8).
For AC powered door strikes, install an
M.O.V. (metal oxide varistor) rated at 50
volts or higher, or Transorb (P6KE15A
or equivalent) at each door strike. When
installed, they will suppress most
problem door strikes.

2. Properly grounding all readers and hardware, in addition to suppressing noise in the peripheral
equipment, should allow for many years of problem free use.
3. In addition, Sentex requires that a separate power supply (appropriate for the type of
strikes or maglocks used) be installed to power door strikes.
4. Before installing the reader, please read the reader wiring instructions in this manual. Damage
may occur if this is disregarded.
5. Installation must meet all local, state, and federal regulations and codes for electrical installation. If
these codes conflict with the installation methods described in this manual, please call your
service representative.

Step 4: Installation of the EM3000 System 13
r
Preparing to Install the EMC and Accessories
1. Locate a 110 VAC junction box that will be
suitable for your EMC installation:
The junction box, in most situations, will already be
installed from a building’s initial installation. The
location of the junction box will be a determining
factor as to where your installation should take place.
The junction box must provide constant power, so
make sure the box does not have an ON/OFF switch
or other means that would shut off power to the
EMCs.
Note: If you cannot locate an appropriate junction box to power the EMC, power the system
directly from the breaker box.
2. Determine which breaker in the breaker box powers the 110 VAC junction box:
With any high-voltage electrical work, a qualified electrician will need to know which breaker
powers the local junction box.
3. Review and pick out locations to mount your EMC(s):
Look for locations that are within 500 ft. of your access control points. Make sure that your
locations are also safe from temperature variations, environmental changes, and access from
outsiders.
4. Review reader and door hardware materials for mounting requirement:
Will you require special tools when installing your system? When installing a reader, always follow
the instructions outlined in the reader’s instruction guide(s).
5. Prep and cut door frames for lock and door sense hardware:
In most cases, the doorframes will be metal. You may need to use metal snips and a drill to size
and secure the lock hardware and your door sense to both the frame and the door itself. For
wooden frames, you may need wood working tools.
6. Cut out dry wall access points for the door hardware and reader:
Where will your readers be located? Make sure that your access points correspond to the
locations where you plan to have your hardware. If you are using REXs or PIRs, make sure
placement of access points are on the opposite side of the wall from the readers.
WARNING
Power to the local junction box
must be OFF during the connection
between the junction box to the 12
VDC power supply board. You may
need to supply extra lighting to the
installation area during the time powe
Doc 6001536, Rev C
Step 4: Installation of the EM3000 System
14
Installing the EMC Cabinet
1. Mount the EMC cabinet:
Use the existing mounting holes to mark the drill
locations onto the mounting surface. Then
remove the cabinet and drill holes that will be
used to secure the cabinet to the mounting
surface. Mount the cabinet using appropriate
mounting hardware.
The location of the EMC cabinet should be near
the 110VAC junction box and with easy access
to the access control points and their hardware.
The cabinet may only be surface mounted.
2. Remove knockouts from the unit:
Connections for the EMC enter the cabinet in
three areas (though actual installation and
entrances may vary).
Door ConnectionsPower ConnectionsReader ConnectionsRS-485 Connections-
You may also wish to mark the entrances around the mounted cabinet to show where
connections will be made to the EMC. To simplify the installation process, decide which access
control point will be Door 1 and which will be Door 2. This will help you decide where door
hardware and reader should be connected first to the EMC.

Figure 9: Mounting Holes and Knockouts
Installing the Reader and Door Lock
1. Pull lock/reader wire to the target doors:
Run wiring from the EMC to both Doors 1 and 2. Remember that wiring for door hardware and
readers differ in both the types of wiring and where wiring is necessary:
Readers:
Door Hardware:
2. At the door and reader locations, pigtail wire out for each lock/reader:
Once you’ve run cable from the EMC to Doors 1 and 2, pull reader wiring through the hole-punch
created in the drywall. Repeat the process with wiring from the different door hardware. Make sure
you give yourself an extra few feet of wire for room to maneuver when making connections.
Doc 6001536, Rev C
The EMC monitors and powers the readers. Run a 6-conductor 22gauge wire from the unit to the target doors.
Locks and PIRs are monitored and controlled by the EMC board but
powered directly from a separate power supply. When connecting
the door hardware, use 2 conductor 18-gauge wire.
3. Splice reader wires and mount both readers
Position the reader at the appropriate
mounting position on the doorframe. To
comply with the Americans with Disabilities
Act (ADA), readers should not be installed
higher than 48” from the ground.
Pull the shielding off both the reader cable
and the wiring pigtailed through the drywall.
The EMC only requires five wires from the
reader to operate. Review the directions that
are supplied with the reader, but the following
rules usually apply:
PWR = red wire
DATA 1 = white wire
DATA 0 = green wire
RTN = black wire
LAMP = brown wire
Note: Check the instructions supplied with
the reader for LED wiring. LED wire color will
vary by reader manufacturer. Also, all LED
functionality must comply with ADA
requirements (e.g., when the EMC grants
access and unlocks a door, the reader’s
green LED must remain lit for the duration of
the unlock cycle).
Splice the wires together and secure using wire nuts or splice caps.
Be sure to cut back drain wires and tape back along with non-used reader wires (see Figure
10).
Drain wire (shield) should be connected at earth ground at the EMC (refer to Figure 6 on
page 10).
Position the reader against the wall. Use a level to assure that the reader is mounted
straight. Mount the reader to the wall using mounting hardware appropriate to the specific
material and type of construction of the wall.
4. Splice and mount the door hardware:
The proper placement and connections for your door hardware depend on the type of equipment
being used. Follow the instructions included with the door hardware on the best way to splice and
mount your hardware. Remember to install your transorb, diode, or MOV at the door lock location
for surge protection.
5. Wire door hardware to the power supply:
Follow the instructions included with the power supply for proper connection of locking hardware.
Follow the same procedure for the other door components (REX, PIR, etc.) that will be used.

Running Cable to Dedicated PC
Set up the connection that will connect the EMC to its dedicated computer. The EMC communicates to
the PC using the RS-485 Converter. Run a shielded cable (such as Belden 1419A) consisting of two (2)
twisted pairs (24 AWG) from the EMC to the dedicated PC.

LOCK WIRING
Wiring the door locks will vary on the type of lock (e.g., Door Strike or Maglock) and "environment"
you wish to employ: fail-safe or fail-secure.
Fail-safe (e.g., Maglock): If the lock loses power (e.g., from a power failure), the door will unlock.
Fail-secure (e.g., Door Strike): If the lock loses power (e.g., from a power failure), the door will
remain locked.
Determine which type of environment to use. Is the access control point an area where people need
to exit in case of emergencies? Does the access control area require its doors to lock after a power
failure (e.g., to prevent vandalism)?

CONNECTING THE RS-485 CONVERTER (EMC TO PC COMMUNICATION)
The EMC communicates to the PC using the RS-485 converter. For a multi-EMC system, connect the
RS-485 converter to the first EMC in the system.
1 Wire the RS-485 converter to the EMC as shown in Figure 19.
One twisted pair will be used for the A- to –485 and B+ to +485 (RS-485 to EMC board)
connections.
One wire from the other twisted pair will be used for the RTN to COM (RS-485 to EMC
board) connection; the other wire of the same twisted pair will not be used.
The cable (Belden 1419A or equivalent) must also have a shield wire attached from the
host PC (at case screw) to the EMC board (at SHIELD).
2 Plug the converter into any available COM port of the host PC (see Figure 18). Note the COM
port number; you will need to assign this number in EMWin.
3 Plug the converter’s power transformer into the appropriate power outlet (input @ 120VAC).

Step 5: Power and Test the EM3000 System
Powering the EMC
1. Make connections between the 12 VDC power supply board and the 110 VAC junction box
(refer to Figure 20): Remember to switch the local breaker to the off position prior to performing
this step of the installation!
WARNING
Do not attempt to connect the 110
VAC junction box to the 12 VDC
power supply unless you are a
qualified electrician. All connections
from the 110VAC junction box to the
12 VDC power supply should meet
National Electrician Code (NEC). High
voltage accidents can be fatal to you
or others.
WARNING
Power to the local junction box
must be OFF during the connection
between the junction box to the 12
VDC power supply board. You may
need to supply extra lighting to the
installation area during the time power
is off.
21
CAUTION
To avoid damaging the
EMC and voiding its
warranty, do NOT
switch the power suppl
board’s power output to
24VDC. The system runs
on 12VDC power only.
Figure 20: Connecting Power to the EMC
2. Power the system via the circuit breaker:
Once the connection between the junction box and the power supply is secure, power the main
system by returning the building circuit breaker to its normal position.
3. The power supply’s status LED (see Figure 21) will light with an amber/greenish glow to indicate
that 110VAC is present and the supply is operating properly.

Step 5: Power and Test the EM3000 System 23
Testing the EMC System
At this point, all the connections have been completed, the unit’s power is ON, and we have not yet started
the EMWin software.
Figure 23: EMC Indicator LEDs
1. Check that the EMC Red Power Indicator is ON.
This is the right-most indicator on the LED array on the front of the board (see Figure 23).
If the LED does not light, go to Problem 1 of the troubleshooting section (see page 27), under
Possible Problems.
2. Press the REX (Request to Exit) button if you have installed one.
This should cause the door strike to energize.
If the door strike doesn’t energize, check the wiring connection from the strike to its power supply
and to the EMC board. Also check the wiring from the REX to the EMC board.
3. Perform this set of steps for each EMC you have installed.
After completing hookup of the EMC, use the EMWin software to verify all other functions. Refer
to the EMWin User’s Guide.
EMC Power-Up Checklist
The EMC Red Power Indicator must be ON (right-most indicator on LED array on front of board,
see Figure 23).
Press the REX button. The Door Strike should activate. If not, check the wiring connection from
the strike to its power supply and to the EMC board. Also check the wiring from the REX to the
EMC board.
Once all readers and REXs are verified, connect the PC to the System.
The Reader(s) Red Activation LED Indicator (RD 0 or RD1) must light when an active card is
swiped.
If the EMWin software and computer have not been installed, please proceed using the EMWin
User’s Guide.

Step 6: Configuring a Multi-EMC System
Communicating with Multiple EMCs (via RS-485)
Once the PC host is connected to one EMC, perform the following steps for each additional unit:
1. Connect each EMC by wiring from P8 from the first EMC board to P7 in the next EMC board. This
format can be repeated in up to 32 total units. The total cable length from the PC to the last
EMC in the system must not exceed 4000 feet.
2. Move the W2 jumper to TOUT for all units except the last one.
Last Unit: W2 jumper in TIN position.
All Other Units: WS jumper in TOUT position.

Addressing Each EMC Through the DIP Switch
The EMC communicates over an RS-485 serial direct connection. The address DIP switch (SW1) is
located at the upper right of the board. Set each EMC DIP switch uniquely in sequential order (from 1 to
32), starting with the first EMC (the one connected to the RS-485 converter at the PC), EMC 1 in Figure
25.

Figure 26: EMC Dip Switches
Step 7: Troubleshooting
Check for these problems first:
1. Faulty Cable connections.
Check the wiring information section, Wiring the EMC, starting on page 16.
2. Overloaded Power Supply.
The power supply board inside the EMC is only
controller board and two (2) reader devices. It is not intended to supply power to electric door strikes
or maglocks; these devices require their own separate, dedicated power sources. Powering electric
strikes or maglocks from the EMC power supply board may cause improper operation of, or damage
to, the EMC board and/or power supply.
Possible Problems
Problem 1: EMC Power LED indicator is not on.
Check power. It could be a defective power supply.
Check wiring from power supply to EMC.
You may have a possible polarity problem. Be sure that the plus (+) lead from the power supply is
inserted into the plus (+) power connection point on the EMC board. Likewise, check that the
negative (-) power supply is inserted into the ground connection point on the EMC board.
Problem 2: Cards are not being read.
Card reader will ‘beep’ when successfully read and sent to the EMC.
Does the reader ‘beep’ when the card is presented?
If not, swipe the card on another reader. If the other reader ‘beeps’ the card, check the first
reader’s wiring.
Problem 3A: The EMWin software does not recognize an EMC.
Verify that the EMC is powered up; refer to Step 5: Power and Test the EM3000 System on
page 21.
Verify that all EMCs have unique address DIP switch settings and that all are sequentially
numbered; refer to Figure 26 on page 26.
Verify the RS-485 connections between all EMCs; refer to Figure 18 (page 20) and Figure 25
(page 25).

Problem 3B: Software shows status of all EMCs as red dots meaning there is no connection from
the EMC to the PC.
Verify that the RS-485 converter is connected to a functional COM port on the host PC; refer to
Figure 18 (page 20). Also, EMWin will select COM 1 as its default port; however, if using another
port, you must manually designate the COM port in EMWin (refer to the EMWin User’s Guide).
Verify the wiring of the RS-485 Converter; refer to Figure 19 on page 20.
Check the RS-485 converter’s plug-in 12VDC power supply.
Verify communication termination (W2 jumpered).
Is the Receive (Rx) LED (Green) flickering?
No- A RS-485 converter fault, COM 1 fault, cabling error, or the program is not running. Note:
The EMWin software should be displaying the controller as a “green” or “yellow” dot at the bottom
of the screen.

Glossary of Terms
Each EMC in a multi-unit configuration must be assigned a unique
number via its Address DIP switch (SW1). Similar to a street
address for homes, the EMC number is the address unit. In the
EMWin, the first EMC is addressed as unit 1.
A semi-conductor “one way valve” that is used to protect the EMC
from power transients caused by D.C. operated door strikes or
maglocks. The diode needs to be installed at the strike or maglock.
The diode is polarized, so care must be taken to ensure that it is
installed correctly. Refer to Figure 15 through Figure 17 on pages 18
and 19.
Door is left open beyond the Door Access Time after a valid opening
by card or REX. A Door Status Contact must be installed for
reporting this condition.
Door is illegally opened without card or REX. A Door Status Contact
must be installed for reporting this condition.
Usually a magnetic contact device (N.C.) used to provide the status
of the door (e.g., closed or open).
A device is considered N.O. if the “normal” condition of the circuit is
not completed or in the “open” state. For N.O. push buttons, pushing
the button completes or “Closes” the circuit. For N.O. Door Strikes,
the N.O. condition will “lock” the door. When the circuit is closed, the
door will unlock.
A device is considered N.C. if the “normal” condition of the circuit is
completed or in the “Closed” state. For alarm devices, the “normal”
condition is the completed or closed circuit. When the circuit is open,
it can become an alarm. For N.C. Door Strikes, the N.C. state is that
the strike will remain locked. The lock will unlock in the N.O. state.
A device to detect body heat and produce a N.O. and/or N.C. output.
Used for automatic exit devices and motion detectors. Requires an
external power source (available in 12 VDC or 24 VDC).
A device used to provide exit out of a protected door without causing
an alarm. A REX device for EMC must be a N.O. device.
A device that protects the EMC from power transients potentially
caused by static or some door strikes. The EMC is built with
transorbs for added protection; however, transients from a door
strike need to be stopped at the strike itself. The supplied transorbs
need to be installed at the door strike.
