Applications
TekMonitors are not programmed using a program language; they
are programmed using a device driver selected from a driver
library and a simple macro selection created from commands
generated by the device driver. The Logic Inputs generate two
types of events that are linked to macros. These input events
occur when the input goes high or low. A macro is basically a
group of commands to provide simple automation.
These
applications provide the system installer with some concepts of
how to apply the TEK 1.
TEK 1
Applications
TEK 1 with Standard Projector Connection
In a standard configuration a TEK
1 is used to control and monitor a video projector or large
screen display. The TEK 1 is installed in the ceiling and an
RS-232 cable with a security wire is connected between the TEK 1
and projector.
Features
Internal timers for Lamp, Maintenance, Monthly Usage,
Total Usage and System Off
Detects cut cables for device security (Reports by Email)
Email Reports including Device Errors, Monthly Usage and
Security Email

TEK 1 with
12 volt Security 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.
Features:
Internal timers for Lamp,
Maintenance, Monthly Usage, Total Usage and System Off
Detects cut cables for device security
Email Reports including Device Errors, Monthly Usage and
Security Email
Enables an alarm if the security cable is cut

TEK 1 with Miniature 24 Volt Security Alarm
TekVox offers
a miniature 24 volt alarm that can operate from the second
Digital Output (DO 2). This alarm operates with the same power
supply powering the TEK 1.
Other devices like the rooms 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 which TEK 1 detects and sets off the
alarm.

TEK 1 with Occupancy Detection and Lighting
Control
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. When
movement is detected, the occupancy detector triggers input 2 on
the TEK 1 which resets the system off countdown timer. If this
timer reaches 0, the TEK 1 shuts down the system including the
lights.
From the TekControl software running
on the room’s PC a message is 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
Features:
-
Internal timers for Lamp, Maintenance,
Monthly Usage, Total Usage and System Off
-
Detects cut cables for device security
-
Email Reports including Device Errors,
Monthly Usage and Security Email
-
Detects movement to automatically power on
and off lights
-
Detects the lack of movement to automatically
shut down the system

TEK 1 with Occupancy Detection, Lighting Control
and
Miniature 24 Volt Security Alarm
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. When movement is detected, the occupancy
detector triggers input 2 on the TEK 1 which resets the system
off countdown timer. If this timer reaches 0, the TEK 1 shuts
down the system including the lights.
A 2K Ό 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.
From the TekControl software running on the rooms PC a message
is 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

TEK 1 with Occupancy Detection, Lighting and
Screen Control
As mentioned
above, the TEK 1 has the ability to operate with an occupancy
detector. Since there are two relays on the TEK 1, it is
possible to control a projection screen or raise and lower a
projector lift.
Features:
Internal timers for Lamp,
Maintenance, Monthly Usage, Total Usage and System Off
Detects cut cables for device security
Email Reports including Device Errors, Monthly Usage and
Security Email
Detects movement to automatically power lights on and off
Detects the lack of movement to automatically shut down
the system

TEK 1 with IR Connection
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.
