Description
The FMTR-2713 is a 27MHz repeater. With its highly sensitive receiver and a 1 Watt transmitter, it is ideal to increase the range of a transmitted signal to 3000 metres. This transmitted signal can be any of Elsema's FMT-… series transmitters. For example the FMT-PET key chain transmitter has a maximum transmitted range of 80 metres, however when used with the FMTR-2713 repeater the effective range is increased up to 3000 metres.
A suitable 27MHz antenna should be connected to the SO239 socket. We recommend the Elsema ANT27L antenna.
The FMTR-2713 can be ordered with a weather proof plastic case or as a Printed Circuit Board (See picture) assembly. This PCB assembly enables customers to integrate the repeater into their own product or case.
The FMTR-2713 repeater comes in three different models i.e. 9510V…, 9511V… and 9512V… . The three models are determined by inserting the correct micro-processor on the repeater board.
Each repeater is factory set and the micro-controller is labeled with the correct model number. All micro-controllers are inserted into a 28-pin IC socket. This socket gives the added advantage of changing the repeater to a different model. Customers must specify which model they require when ordering the repeater.

Instructions
FMTR-2713A is using the 9510V… Micro-Controller. The repeater is checking the first 8 bits of the received word and if it is matching its own 8-way code switch, will re-transmit these 8 bits together with the last 4 bits it received. This model can be used when a group of transmitters should be repeated (Not all transmitters). If a multi channel receiver (Such as FMR204-12) is used to receive the repeated transmission, each transmitter, which transmits into the repeater, can be identified. For example, a building with 16 transmitter smoke detectors (Elsema's TSD-1), a 16 channel receiver can indicate which smoke detector is transmitting.
The 2-way mode switch (Between the supply terminal block and the 12-way code switch) has no function and is reserved for the future use. |
FMTR-2713B is using the 9511V… Micro-Controller. This model uses the 2-way mode switch (Between the supply terminal block and the 12-way code switch), allowing four different modes of repeating.
2-way Mode Switch Configuration of FMTR-2713B is as follows:
Switch 1 - Repeat Modes |
| ON |
It is comparing all 12 bits of the received word with the 12-way code switch and if matching, will re-transmit this unique code . |
| OFF |
It is comparing the first 8 bits with code switches 1 to 8, and if matching, will re-transmit this 8 bits, together with the current data on code switch inputs 9 to 12. |
Switch 2 - Response Time |
| ON |
Repeater will transmit as soon as correct received word is matching the 8-way or 12-way code. |
| OFF |
Repeater will transmit after reception of correct code has ended . |
|
FMTR-2713C is using the 9512V… Micro-Controller. Repeater will repeat any received 12 bit code switch data. The repeated data is re-transmitted as opposite data . Therefore an “on” received, by the repeater, is repeated as an “off”. Care must be taken when a 27MHz receiver receivers this re-transmitted code that the code switch setting is opposite to the original transmitted signal.
This type of repeater will respond to any of Elsema's FMT-… series transmitters. It should not be used in an area or location where other transmitters for garage doors, alarms, etc. are expected since the repeater would splatter the 27MHz frequency.
2-way Mode Switch Configuration of FMTR-2713C is as follows:
Switch 2 - Transmission Mode |
| ON |
Repeater will transmit as soon as a valid ELSEMA code is received. |
| OFF |
Repeater will transmit after reception of the ELSEMA code has ended . |

Special Versions
9512V609A: Same as 9512V, except data is opposite and receiver is disabled for 4 seconds.
9512BV05: Same as 9512V, except data is not opposite and receiver is disabled for 4 seconds.
Please Note:
• After a valid reception, all 3 models are repeating the transmission for 0.5 seconds only (Optional times are available), after which they go back into receive mode to check for another valid reception.
• The 12-way code switch is inserted into a socket. This enables the user to replace the 12-way code switch with a 8-way code switch and use 9 to 12 for data. An 8-way code switch is available from Elsema.
• The repeater has an on board red LED which indicates that a code is repeated (transmitting).
