27MHz REMOTE CONTROL DIGITAL TRANSMITTER

Features

Works in the 27MHz band

Maximum reliability provided by Surface-Mount technology

High security by 12-way code switch enabling 4096 codes

Durable plastic case

2 Channel (FMT-302) and 4 Channel (FMT-304) are also available

Application

A remote control switching device for various uses e.g. garage doors, lights,

gates, and automatic telephone dialers

A personal security alarm activator for home safety or cash carrying

businesses e.g. banks, shops, service stations, etc.

A calling device for the elderly or handicapped

Description

Buzzer indicates the status of the transmitter. To activate the transmitter, simply press the button at the front.

Buzzer will be on when the transmitter is activated.

Working in the 27MHz band, the FMT-301 achieves the highest possible standard of performance by

employing a crystal-controlled, frequency modulated radio signal. The microcontroller with the latest surface-

mount technology provides maximum reliability.

High security against false operation is achieved by a 12-way code switch (part of the digital encoding system)

which is used in place of the usual 8 or 10 way systems from other manufactures. This enables the user to

select any one of the 4096 codes available. The code can be easily changed at any time.

Operating Distance

An operating distance (in conjunction with our FMR series receivers) of 200 metres is possible.

The operating distance depends upon the receiver antenna and location. An independent test revealed the

following ranges:

Range tests were done in an open area test site with line-of-sight operation and the receiver antenna wire was

fixed vertically, away from any metal objects.

When operating near its range limit, some improvements may be obtained by pointing the transmitter towards

the receiver. This is due to its slightly directional properties.
