Applications
TekMonitors are not programmed like other control systems using a program language; they are configured
using a PC application called TekWizard. With some IT experience an installer is able to configure a TekMonitor
by following the step-by-step guide in TekWizard. Although there is no programming, TekWizard does provide
for some logic operations in the creation of macros. A macro is just a list of commands executed by a logic
input, software, user or time event. A macro is basically a group of commands to provide simple automation.
The Logic Inputs generate two types of events that are linked to macros. These input events occur when the
input goes high (open circuit) or low (connection to ground).
These applications provide the system integrator with some concepts of how to apply the TEK 1. Within
TekWizard are templates that coincide with these applications.

Standard Projector Connection
TekWizard Template: TekVox – Standard
In a standard configuration a TEK 1 is used to control, monitor and provide security for a video projector or
large screen display. The TEK 1 is installed in the ceiling and a control cable is installed between the TEK 1
and the TekSecurity warning indicator. TekSecurity is installed on the projector and a short control cable is
installed between TekSecurity and the display device.
Installing TekSecurity on the video projector adds a theft deterrent by flashing a Red LED on the TekPatrol
Security Logo when security is enabled. This indicator also lets a service technician know that the projector
is under security and to disable security before working on it.

12 volt Security Alarm
TekWizard Template: TekVox – 12V Alarm
Adding an alarm to a TEK 1 provides extra security for a video projector in a classroom. Most alarms
operate on 12 volts and draw about 500 milliamps. For these types of alarms use a separate 12 volt power
supply and one of the TEK 1 relays to operate the alarm.
Other devices like the room’s PC and monitor can also be protected by TEK 1. This is accomplished by
looping a security wire from one of the unused Logic Inputs on the TEK 1, through the PC and monitor, and
then back to ground on the TEK 1. For someone to remove any of these monitored items they must first cut
the security wire. Cutting the security wire removes the ground from the monitored input causing an alarm
event macro to be executed.

TEK 1 with Occupancy Detection and Lighting Control
TekWizard Template: TekVox - Occupancy1
Occupancy detection for lighting has become a required device in most new installations. To improve the
performance and operation of the lighting control, the TEK 1 has the ability to interface with an occupancy
detector and lighting controls. When motion is detected, the occupancy detector triggers a high event on
Input 2 of the TEK 1. Once motion is no longer detected, the occupancy detector triggers a low event on this
input.

Macros
Motion –
If System Power is On - The system off countdown timer is stopped and reset.
If System On is Off - The lights go on.
No Motion –
If System Power is On - The system off countdown timer runs. If this timer reaches zero, a system off Macro
is called, shutting down the system.
If System Power is Off - The lights go off.
A 2K ¼ watt resistor is used to create an off state for the occupancy detector. When the occupancy detector
is off, its output floats causing the TEK 1 to think it is on. Placing this resistor between the input and ground
creates an off state for the occupancy detector.
If the TekControl software is running on the room’s PC, a message can be displayed that the system is
about ready to shut down. This allows the user to reset the system timer from the PC. Lights can also be
controlled by the user from the PC.
This method of controlling the lights from the TEK 1 solves the problem with the lights automatically shutting
off when there are only a few people in the room. Also, the TEK 1 can power off other devices when no one
is in the room, thereby saving energy and extending the bulb life of a video projector
Note that when using a Digital Output to control a lighting power pack, the logic is reversed. This means
when power is first applied to the TEK 1 the Digital Output is in an open state, causing the pull-up resistor to
supply current to turn on the power pack. Once the TEK 1 is running, a command is issued to turn on this
output causing the power pack to go off. Using a relay solves this problem.

As mentioned above the TEK 1 has the ability to operate with an occupancy detector. Since there is an extra
logic output, a miniature alarm can be added to the TEK 1.

IR Control
In some installations the display device only has IR control. For these types of installations the TEK 1 is not able
to communicate directly with the device. With a few add-on products the TEK 1 can monitor and control these
types of devices. Below are some suggested add-on type devices and how to use them with the TEK 1.
It may not be necessary to control the projector. The projector may already be controlled by an IR device. For
these installations all that is required is to determine if the projector is on or off by using only a power current
sensor.
By adding a power current sensor at the display device the TEK 1 can determine if the device is powered on.
Once the TEK 1 knows the device is on, the internal lamp and maintenance timers within the TEK 1 are
operable.
Power Current Sensor
• AMX PCS
• Display Devices PCS-02
To control the display device add a programmable RS-232 to IR. The TEK 1 can then be programmed to
communicate with the IR module.
Programmable RS-232 to IR module
• Xantech RS232IR Module
For security monitoring use the TekSecurity cable and connect the Security connection to a ground connection
on the display device.
Features
• Internal timers for Lamp, Maintenance, Monthly Usage, Total Usage and System Off

• Email Reports including Device Errors, Monthly Usage and Security Email
• Allows for IR only controlled devices
• Determines if the monitored device is actually powered on
