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 (m)
Receiver Antenna
Receiver Type
40
250mm wire
FMR-… series
Up to 200
ANT27M
FMR-… series
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.
