Description
The FMT154… has a transmission power of 1000mWatt. It gives a controlled range of up to 5km. The controlled
operation can be any electronic or electrical operated device when used with the FMR154… series of receivers
The channels are activated via screw type terminals onto which the user can connect reed switches, toggle
switches, push buttons or any form of normally open (NO) contact.
The transmitter uses a frequency of 154MHz and a modulation type of Narrow Band Width FM which makes it
suitable for industrial applications where you would have a high level of electrical interference. This transmitter is
not affected by man made or electrical interference. This makes FMT154... an ideal choice for use in heavy
industrial environment.
Each transmitter button is individually transmitted to the receiver making it possible to do simultaneous channel
transmission. This means that up to 8 different functions can be done at the same time. Each button can operate
any FMR154… series receivers making it possible to transmit each button to different single channel receivers or
to multi channel receivers
The transmitter uses a specially programmed micro-controller which ensures the highest reliability, low standby
current consumption (10uA) and greater flexibility. The greater flexibility allows customers to contact us and
request custom written software for special functions.
External supply connection and SO239 antenna socket is provided with the transmitter.

REGULATORY COMPLIANCE STATEMENTS
American Users
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference and
(2) This device must accept any interference received, including interference that may cause undesired operation.
FCC Notice
This device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This device generates, uses, and can radiate radio frequency energy and, if installed and
used in accordance with the instruction, may cause harmful interference to radio communications. However, there
is no guarantee that interference will not occur in a particular installation. If this device does cause harmful
interference to radio or television reception, the user is encouraged to try to correct the interference by one or
more of the following measures:
•
Reorient or relocate the receiving antenna.
•
Increase the separation between the equipment and receiver.
•
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•
Consult the dealer or an experienced radio/TV technician for help.
Caution: Any changes or modifications not expressly approved by the grantee of this device could void the user’s
authority to operate the equipment.
