Installation Instructions
Installation Instructions
Read and adhere to all safety warnings in this manual before installing
the Informer TAR.
To prevent injury, this apparatus must be securely attached to the wall
in accordance with the installation instructions.
Determine a Suitable Location
When choosing a location for the Informer TAR, consider the following criteria:
1. Place as far as possible from electrically noisy electronic devices to avoid
interference. Examples of noisy devices may include the following: microwave
ovens, motor driven devices, light ballasts, and electrical switching devices.
2. Conductive building materials can block radio waves from reaching the Informer
TAR. In some areas, you may require a larger antenna or an external antenna that
provides more signal. You can monitor radio reception by holding down the
MONITOR button until audio is heard from the speaker (if the monitor function
was programmed into the Informer TAR). Monitor the clarity of speech to ensure
it is clear and intelligible and does not cut in and out. Activate the unit from the
Informer TAR control station to verify it is programmed correctly and is
receiving the control signals.
3. Position to keep the unit at least six inches away from the listener’s ears to avoid
potential hearing damage.
4. Place in an area where you can hear the speaker when the unit is activated. You
can check the level of the warning tone by holding down the MONITOR and
RESET buttons together until you can hear the Alert beeps. It the coverage area is
large, you may require multiple TARs or external amplifiers and speakers to
provide adequate warning.
5. Do not use near water; for example, near a bathtub, washbowl, kitchen sink,
laundry tub, in a wet basement, near a swimming pool, rain or similar
environments.
6. Place within six feet of an AC power receptacle to eliminate the need for an
extension cord.
7. Place where it will not be inadvertently covered or moved. A permanent wall
mounting is recommended after you have found a suitable location.

The following sections describe the various features and functions of the Informer
TAR. Please refer to the following figure.
Figure 3 Informer TAR Keypad
Power Supply
Your Informer TAR comes with a power supply. Keep it plugged in at all times.
When the Informer is plugged in and receiving power, the Power LED displays a
steady green light. The Informer TAR also comes with a sealed valve regulated
rechargeable battery. The battery requires continuous charge in order to maintain its
effectiveness. In the event that AC power to the Informer TAR is lost, the green
Power LED on the unit begins to flash to indicate the use of battery power.
IMPORTANT: The Informer TAR should not be turned off; therefore, the unit must
remain connected to the power supply to avoid depleting the battery.
Connect the Informer TAR to a 9 VDC, 500 mA power supply, which is provided
with the unit. Allow the battery to charge for at least 24 hours initially and after a
complete discharge before relying on the battery backup feature.
