Accessories
Terminal Block
A variety of wired accessory items can be connected to the 
terminal block such as Safety Infra-red Beams, wall switch, 
door status indicator and more.
The  terminal  block  also  features  and  auxiliary  output  for 
controlling other devices from your transmitter. These can 
include: an alarm system, external lighting, or an automatic 
gate.
Terminal connections are as follows (Fig. 40):
PWR (+ve)
IR (Safety Infra-red Beam input)
IR(0V) (Common for Safety Infra-red Beam) 
COM (Common -ve ground for accessories)
OSC (Open/Stop/Close trigger)
AUX (Auxiliary output trigger) 
Remote Aerial (Part No 062177)
Some  sites  cause  poor  radio  reception.    Particularly 
problematic areas are those where there is a large amount 
of  metal,  like  an  all  steel  garage,  or  an  underground  car 
park with large masses of steel reinforced concrete. These 
issues, and others, can create radio reception issues. 
Poor radio reception will be noticed by a reduction in the 
operating range of the transmitters.
You can evaluate whether fitting  an external aerial will 
benefit as follows:
test  the  maximum  operating  range  of  the  transmitter 
with the garage door closed; then 
test the maximum operating range of the transmitter 
with the garage door open. 
If the range improves when the door is open you can install 
a remote aerial kit to improve reception.
Mount  the  aerial  to  a  suitable  location  on  the  outside  of 
the  garage.  Similar  to  a  television  aerial,  the  better  the 
mounting position the better the reception will be.  Where 
possible, mount the aerial as high as possible, away from 
masses of metal and in a line of sight position to where you 
normally use your transmitter.
