Low Battery Output
The low battery feature informs the user that the Tx encoder used has a low voltage battery.
The LOW BATT channel operates if the Rx decoder has received a transmitted signal with low voltage signal
present. This will continue to operate until a transmitted signal without the low voltage signal has been
received.
NOTE:
The LOW BATT relay is NOT fitted as standard, a relay of type BT47W/6 or equivalent can be used.
Expanding the system to 15 Relay outputs
The EX115C16A unit is available to connect directly to the ‘105’ Series Decoder providing 15 momentary relay
outputs. For further information please see Datasheet DS115.

Press and release the programming switch (SW1)
Note that the Learn LED will illuminate
Depress and release the transmitter once, LED on the decoder will extinguish
Depress and release the transmitter again, LED on the decoder will flash
After the LED has stopped flashing the transmitter has been successfully taught to the decoder
This transmitter will now operate the system
Golden Transmitter:
A special ‘golden transmitter’ encoder is available which when operated, causes the
same function as the user pressing the ‘Learn Switch’ This enables ‘remote Learning’ (for applications where
the ‘105’ decoder is inaccessible. For further information please contact our sales dept.
Erasing Existing Tx Encoder
1. To completely erase the Tx encoders, press SW1 on the Rx decoder for 10 seconds.
2. The learn LED will turn off after the 10 seconds to indicate the Tx encoder(s) have been erased
NOTE:
You cannot erase individual Tx encoders
**Range
Please note that all radio systems are dependant on a radio signal being received through airspace.
The range quoted is the optimal in direct line of sight without obstacles and in good atmospheric conditions.
Range is affected by many things, e.g. local environmental conditions, atmospheric conditions, interference
from other radio transmitters.
In very worse case applications the range quoted may be reduced to 30% of the optimal range stated.
