Using R.F. Modems |
|
In sites where the communications cable would be very expensive to fit (e.g. across a concreted yard) we can supply RF Modems to bridge the gap. The standard modem links can operate at up to 800m line of sight with up to 4000m available on special order. Click on the wiring diagrams below to open high resolution .PDF copies. |

Important Note: This system requires switching to a 2-wire communications system compatible with Keypads V3.27 or later using interface V3.08 or later |
