The TEL-ALARM is a telephone, a motion sensor, and a microphone at the same time and you can use it as an ordinary telephone, until you decide to treat it as a monitoring system. Simply enter any telephone number you choose and turn on the motion sensor.
The TEL-ALARM operates from any phone line, requires no installation, and is completely portable.
PART SPECIFICATION
Phone
The TEL-ALARM circuitry requires an AC adapter (provided) to be plugged into any standard 110V wall outlet. The absence of this power adapter doesn't cause any serious problem but only a lower power. You can connect your TEL-ALARM to any existing phone line like another ordinary phone.
The TEL-ALARM motion sensor is Passive Infrared Technology (PIR). The passive infrared sensor detects changes in the room's heat signature due to occupant motion. The range is in excess of 30 feet at which point the width is about 20 feet, creating about a 45 degree wedge beyond the sensor origin (see the picture on the right).
MicrophoneThe hidden condenser microphone is amplified to insure that sounds are heard in the best way.
