• Single channel long range transmitter (2-3Kms range)
• Can be triggered by panic button or external devices
• Pin SIGNAL OUT : from transmitter
• Pin SIGNAL IN 1 : for channel 1
• Pin SIGNAL IN 2 : for channel 2
• Pin SIGNAL IN 3 : for channel 3
• Pin SIGNAL IN 11 : for channel 11
• Loopback SIGNAL OUT to particular SIGNAL IN to make respective
channel active (refer to pic:1 and 2)
Loopback can be done using external RELAY contactor points
