Users Manual
2, 4, 8-Input 154.6MHz Transmitter 154.6 MHz Transmitter Features • Long range – up to 5km. • 1 Watt Transmitter • Not affected by Natural or man-made electrical interference • Specially programmed micro-controller • Simultaneous channel transmission is possible; i.e. more than one channel can be activated at a time. Application • Pump Control • Long distance panic button • On/Off applications in agricultural devices • Security alarm • Basic Telemetry eg. Water level indication 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.

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.
