When Installing Controllers
DO
• since this is a telephone entry system at least one phone line will be necessary, it is important to plan ahead to meet
power and telephone requirements for your system (if using a modem, the host computer will need 1 phone line, plus
one for each master controller in each network or each EntraGuard unit)
• mount controllers in environmentally suitable areas - the EntraGuard Titanium unit is weather resistant, but care
should be taken to avoid areas of weather/temperature/humidity extremes
• mount the controller at least 3 feet away from the controller's power supply to prevent EMI radiated from the power
supply from affecting the controller
• use the enclosure as a mounting template to mark drilling holes for permanent mounting
• note the locations of the knockouts in the enclosures and remove the appropriate knockout for the easiest cable
routing into the controller
• route all controllers in a network in a single, continuous daisy-chain (with the EntraGuard Titanium controller as the
master)
• route cables in accessible areas for ease of maintenance
• connect all controllers to a quality earth ground1
• add transient suppression across electric devices attached to a controller output
• use an isolation relay (P/N IRP-1) if attaching to a parking gate, a turnstile, or any application using a large electric
motor
• verify the controller's supply voltage is 12 VDC – long power line runs cause a drop in voltage at the end of the run
• verify proper operation of the host computer's COM port or Ethernet/LAN WAN connection.
DO NOT
• make modem phone line connections through PBX telephone switching systems - most modems are not compatible
with PBX systems leading to disconnection problems with the modem
• locate the EntraGuard Titanium controller near EMI sources - EMI sources can affect the performance of the
controller
• use switching power supplies - they are EMI sources
• route network cables beside power cables - transients on the power cables may be picked-up by network and reader
cables
• stretch or over-tension cables
• route over sharp objects
• let the wires get tangled
• route the EntraGuard Titanium controller as a slave to a PXL-250 master
• route all controllers in a network in spur, hub, or loop configurations
• connect earth ground1 to the network cable shield - the EntraGuard Titanium automatically connects earth ground to
the shield at one point on the network to prevent ground loops
• use gender changer plugs when making RS-232 serial communication connections (unless you know it is a "straightthrough" plug) - gender changers may have internal wiring changes that can disrupt communications

Connecting a Door Status Input
Each EntraGuard Titanium controller is shipped with an installation kit including all necessary terminal blocks and
transorbs. One of these terminal blocks has a jumper across pins 1 and 2. This terminal block is designated for use on TB4. If a door switch is not used on the controller, this jumper prevents a continuous door open status alarm from being
received by the controller. If a door switch is used, simply remove this jumper and install the door switch leads.

Communication
The communication section handles three different, but related, topics:
•
•
•
Communication between EntraGuard Titanium controller and tenants
Communication between the master EntraGuard Titanium controller and the host computer for programming
Communication between networked EntraGuard Titanium/PXL-500/510 controllers
NOTE: Keri Systems recommends performing a bench test on each unit prior to installation to rule out any phone line
problems.
5.1
Between EntraGuard Titanium Unit and Tenants
The telephone communication is done via a copper phone line to TB-15. Connect the TIP line to either Pin 1 or Pin 2 then
connect the Ring line to the other Pin (see Figure 12).
Figure 12: TB-15 Phone Line Wiring Connection
There are three ways of connecting the phone line for communication between the EntraGuard Titanium unit and the
tenants.
5.1.1
Single Phone Line for a Single EntraGuard Titanium Unit
For a single EntraGuard Titanium unit, connect the phone line to TB-15 on the EntraGuard Titanium board (see Figure
2 on page 2).
5.1.2
Individual Phone Lines for each EntraGuard Titanium Unit on a Network
The set up for individual phone lines for each EntraGuard unit is the same as for a single phone line for a single
EntraGuard Titanium controller. Each phone line is connected to TB-15 on each EntraGuard Titanium board.
5.1.3
Shared Phone Line for Multiple EntraGuard Titanium Units on a Network
A single phone line may be shared for communication between multiple EntraGuard Titanium units and tenants. The
phone line is plugged into TB-15 on the master EntraGuard Titanium unit with the phone line then going out of the TB-15
phone plug to the next unit’s TB-15 and so on to all the networked EntraGuard units (see Figure 13 on page 12).
NOTE: Sharing a phone line for multiple EntraGuard units is limited to a maximum of 6 units per phone line.

5.2
Between EntraGuard Network and Host Computer
A communication link between the EntraGuard network and the host computer is provided via one of two ways.
•
•
using the phone line connected to TB-15
using the RS-232 serial port
NOTE: In order for monitor mode to work, the RS-232 serial port method must be used (see Section 5.2.2 on page 14).
5.2.1
Phone line (Internal Modem)
The EntraGuard Titanium controller’s internal modem may be used for communication between the master controller and
an external modem1 connected to the host computer. To use the EntraGuard’s internal modem, attach the phone line to
TB-15 located on the master controller’s board (see Figure 2 on page 2).
NOTE: If you are using two separate phone lines, one for communication with the tenants and one for programming, you
will not be able to use the internal modem for programming and must use an external modem connected to the RS-232 as
described in Section 5.2.2.2 on page 16.
Once the phone line has been attached, the J11 jumper must be set for proper operation. When using TB-15 phone line
connection for communication with the host computer, place the jumper on the INT_MODEM jumper (see J11 on Figure
2 on page 2).
The Doors software must also be configured for using the internal modem. In the Doors software, click on the
button, then select the Network Config tab. In the “Modem Init String” field type in AT&K02 (see Figure 14). Click on
the
button.
Figure 14: Modem Init String Set
NOTE: For wiring of an external modem to the host computer, see Section 5.2.3 on page 18.
1. You must use a Keri Systems modem for proper communication.
2. Although it is not necessary to enter this code with every type of modem, Keri Systems recommends you
enter it in all situations for proper communication between the master controller and the host computer.

EntraGuard® Titanium Telephone Entry Controller
Quick Start Guide
5.2.2
RS-232 Serial Port
Using the RS-232 serial port for communication between the EntraGuard unit and the host computer may be done one of
two ways:
•
•
by direct connect
through an external modem.
For either of these options, the INT_MODEM J11 jumper should not have a jumper across it. Verify there is no jumper set
across J11 (see Figure 2 on page 2) when using the RS-232 serial port for communication.
NOTE: Do not use male/female gender changer plugs or 25-pin to 9-pin adapters when making RS-232 serial port
connections. These devices may have internal wiring changes that can disrupt communications when implemented in
conjunction with the Keri Systems serial wiring instructions. If you must use a gender changer plug, ensure it is a
“straight-through” plug.
NOTE: When using 56K modems to communicate with remote access control networks, all modems must use the same
communication format - either X2 or Flex. Incompatibilities between the two formats make some modems of one format
incapable of reliable communication with modems of the competing format. Modems using the V.90 specification are
compatible regardless of whether they are from an X2 or Flex manufacturer.

Direct Serial Connection – Controller to PC
To make the connection between the EntraGuard master controller and the host computer you will use one cable.
•
•
If the host computer has a male DB-9 connector on the serial port, you must use a Keri Systems KDP-252 cable or
create a cable according to the drawing in Figure 15.
If the host computer has a male DB-25 connector on the serial port, you must use a Keri Systems KDP-251 cable or
create a cable according to the drawing in Figure 16 on page 15.
The Keri Systems part number for this cable is KDP-252.

5.2.2.2
Modem to Controller
To make the connection between the master controller and the host computer you will use two cables: one between the
host computer and its modem (see Section 5.2.3 on page 18), and one between the master controller and its modem.
•
•
•
If the modem has a female DB-25 connector, you must use a Keri Systems KDP-336 cable or create a cable as shown
in Figure 17.
If the modem has a female DB-9 connector, you must create a cable as shown in Figure 18.
If the modem was purchased from Keri Systems, it comes with an adapter that accommodates a female DB-9
connector (should the modem have a DB-9 instead of a DB-25 connector). Use this adapter cable in conjunction with
a KDP-336 cable to make the modem/controller connection. See Figure 19 on page 17.
The Keri Systems part number for this cable is KDP-336.
Figure 17: Modem/DB-25M to Telephone Entry/TB-12 Serial Port Connections
The Keri Systems part number for this cable is KDP-929M.

Modem to PC Serial Connection
Keri Systems does not provide this cable. It is an off-the-shelf item from any computer supplier or electronics store, and
its configuration is dependent upon the configuration of the serial port on the host computer. Based on the serial port, there
are four possible cables.
•
•
•
•
If the modem has a male DB-25 connector and the host computer’s serial port has a female DB-9 connector, purchase
or create a cable as shown in Figure 20.
If the modem has a male DB-25 connector and the host computer’s serial port has a female DB-25 connector,
purchase or create a cable as shown in Figure 21.
If the modem has a male DB-9 connector and the host computer’s serial port has a female DB-9 connector, purchase
or create a cable as shown in Figure 22 on page 19.
If the modem has a male DB-9 connector and the host computer’s serial port has a female DB-25 connector, purchase
or create a cable as shown in Figure 23 on page 19.
NOTE: Keri Systems requires using modems from the same manufacturer at both the host computer and the access control
network. This eliminates the possibility of incompatibilities between modems from two different manufacturers from
affecting the communication between access control network and host computer. Keri Systems cannot be held responsible
for problems caused by incompatibilities between modems from two different manufacturers.

Verify the 12 VDC Supply Voltage
To verify the 12 VDC supply voltage:
1.
2.
3.
4.
5.
Turn system power on.
Set the DVM to a DC volt scale capable of reading 12 VDC.
Place the Red DVM lead on Pin 1 of TB-2.
Place the Black DVM lead on Pin 2 of TB-2.
Check the DVM reading. It should read +12 VDC +/- 2 volts.
If the DVM does not read 12 VDC (+/- 1.5 V), verify the power supply is of the correct voltage, verify the cable length
does not exceed 200 feet, and verify the cable gauge is AWG 18.
NOTE: On long power cable runs, keep in mind the resistance in the cable itself causes a drop in voltage at the end of the
run. The power supply must be able to account for this voltage drop.

Setup Controller
If you're turning system power on for the first time, certain tasks must be performed prior to entering access control
information from Doors. On the EntraGuard Titanium main board (see Figure 2 on page 2), hold the Reset Button (SW1)
down and turn the controller’s power on. After the controller beeps once, indicating the controller’s firmware is ready for
programming, release the SW1 button. The LCD on the front panel will display the Reset Menu (see Figure 25). From this
menu you may perform different tasks such as set the controller’s address, clear the controller’s memory, set the
microphone gain, and check diagnostics.
Figure 25: Reset Menu
NOTE: If no keys have been selected within 60 seconds, the unit will time out and go directly to the default message. In
order to reach the Reset Menu, the unit must be powered up again.
Page 21 of 26

EntraGuard® Titanium Telephone Entry Controller
Quick Start Guide
7.1
Set Unit Address
The controller’s address may only be set through the Reset Menu. Once you have performed the necessary steps to reach
the Reset Menu as described above, if the EntraGuard Titanium unit has an alpha/numeric keypad, the keypad will default
to the numeric keypad (if the alpha keypad is lit instead, press the #/A key to return to numeric mode). To set the desired
operating address for the controller, press 1 on the keypad. The Set Panel Address screen appears on the LCD (see Figure
26).
Figure 26: Set Unit Address
The address range is from 1 to 128. The Master Controller must be set to address 1. Other slave EntraGuard/PXL-500/510
controllers may be assigned any number from 2 to 128. If the network is made up of PXL-250s, the EntraGuard Titanium
must be set as the Master.
If the address shown as Current is correct, you may either enter the same address and press *, or just press * to return to
the reset menu. If you do not enter a new address, or enter the same address that is already assigned to this unit, you will
need to clear the memory separately (see “Clear the Controller’s RAM’’ on page 24).
NOTE: Changing the address of an EntraGuard Titanium controller completely erases all information within the
controller. It is vitally important that you collect all data from the controller before changing the address. Once the
address is changed (and the RAM is automatically cleared) the information in the controller is lost and cannot be
recovered.
If the address shown as Current needs to be changed, enter the new address by pressing the numbers on the keypad. The
number selected will show in the New line. If you enter the wrong number, simply press CLEAR to erase what has been
entered. When you are satisfied with the address entered, press *. If you have changed the number from what is shown as
Current, the controller will automatically clear the memory as it changes the address (see Figure 27).
Figure 27: Clearing Memory
Once the memory has been cleared, the unit is ready to be configured. The LCD will display a warning that the unit has
not been initialized (see Figure 28 on page 23). This display will rotate with the EntraGuard Default display (see Figure
29 on page 23) until a Total Update from Doors has been performed on the unit. Once an update has been performed, only
the default will be displayed.

NOTE: Any time the “Not Initialized Unit Warning” appears on the LCD display, the unit needs a Doors update.
Figure 29: EntraGuard Titanium Default LCD Display
NOTE: The default display will remain until a message banner has been created (for instructions on how to create a
message banner see the Doors Users Guide - P/N 01914-100). Doors treats the Entraguard Gold and Entraguard
Titanium the same, so this message will show the EntraGuard Gold banner in an Entraguard Titanium unit.
7.1.1
The Master Controller1
The Master Controller must be set to address 1 so that all slave controllers on the access control network can identify the
master controller. For the Master Controller to correctly identify all slave controllers on the network, one of two things
must be done.
1.
The master controller must be the last unit on the network to be powered on. This ensures that when the Master
Controller begins polling the network to see what slave units are connected for system configuration, all slave units
are ready to communicate their unique addresses and their configuration information.
2.
The Auto-Configuration routine within the Doors program must be run. This instructs the Master Controller to poll
all controllers on the network for addresses and configuration information.
NOTE: An auto-configuration must be performed any time changes are made to the 485 network.
1. The EntraGuard Titanium Controller must be installed as the Master Controller only in a mixed EntraGuard/
PXL-250 network.

7.2
Clear the Controller’s RAM
When turning system power on for the first time, the controller’s memory needs to be cleared of any spurious information
that may be in the RAM. If you changed the controller address, the memory is automatically cleared. However, if you did
not change the address, you will need to clear the controller’s RAM separately. From the Reset Menu (see Figure 25 on
page 21), press 2 to Clear Memory. The Clear Memory screen will appear on the LCD (see Figure 30).
Figure 30: Clear Memory
From the Clear Memory Screen you may either:
1.
Press 1 to clear the controller’s RAM. The LCD will change to show the memory is being cleared (see Figure 27 on
page 22). Once the controller’s RAM has been cleared, the unit is ready for use. The LCD will rotate between the
Initialization Warning and EntraGuard Default screens (see Figure 28 on page 23 and Figure 29 on page 23) until a
Total Update from Doors has been performed on the unit.
or
2.
Press 2 to return to the Reset Menu without clearing the controller’s RAM.
NOTE: Clearing the system RAM completely erases all information within the EntraGuard Titanium controller, except for
the controller address. If there is any information in system RAM from an access control installation and the system RAM
is cleared, the information in the controller is lost and cannot be recovered.
7.3
Set Microphone Volume
When turning system power on for the first time, the microphone volume should be left as it has been set in the factory.
However, if the microphone volume needs to be changed, see the “Set Microphone Volume” section in the EntraGuard
Troubleshooting and Diagnostics Guide (P/N 01912-001).

General Information on Inputs
A controller input detects a state change generated by a device outside the controller that may prompt a response from the
controller. Input devices that generate a state change may be normally closed or normally open. This section provides a
brief description of normally closed versus normally open inputs.
8.1
Normally-Closed
A normally closed input device continually keeps a circuit active or complete. A state change is generated when the
normally closed input device is forced open, breaking the circuit. In an access control system, a door switch is a typical
example of a normally closed device. While the door remains closed, the switch remains closed. When someone opens the
door, the door switch is opened, breaking the circuit and generating a state change. The controller then responds to the
state change and generates an output (such as sounding an alarm if the door is a secure door).
8.2
Normally-Open
A normally open input device continually leaves a circuit open, or incomplete. A state change is generated when the
normally open input device is forced closed, completing the circuit. In an access control system, a request-to-exit (RTE)
button is a typical example of a normally open device. In an access control installation, an RTE button is located on the
secure side of a door. While there is no one there pressing the button, the switch remains open. When someone desires to
exit through a secure door, they press the RTE button, closing the circuit and generating a state change. The controller
then responds to this state change and generates an output (such as unlocking the door to allow egress).
9.0
General Information on Safety versus Security with Door Locks
When installing a door lock there are two things to consider: safety versus security, or should the door be “fail-safe” or
“fail-secure”.
9.1
Fail-Safe Door Lock
Fail-safe means that if the power should fail at a door (perhaps due to a power outage or equipment failure), the door will
automatically unlock allowing entrance or egress. Power is required to keep the door locked. A fail-safe door ensures
people will be able to enter and exit a secured area through that door in the case of an emergency. A typical fail-safe
application may use a magnetic lock. In this application, the controller energizes the lock relay, causing the lock relay to
change its state. In its new state the normally closed circuit is opened breaking the power to the magnetic lock and
allowing the door to be opened.
9.2
Fail-Secure Door Lock
Fail-secure means that if the power should fail at a door (perhaps due to a power outage or equipment failure), the door
will automatically lock and not allow entrance but will continue to allow egress. Power is required to unlock the door. A
fail-secure door ensures a secured area remains secure regardless of the situation. A typical fail-secure application may
use a door strike. In this application, the controller energizes the lock relay, causing the lock relay to change its state. In its
new state the normally open circuit is closed activating the release mechanism for the door strike on the door to be
opened.
