ENC-3300-DTMF

External Switches

The ENC-3300-DTMF has connections for external, momentary, dry contact switches supplied by the
customer.

Please Note: Damage will result if any external voltage is applied to these connections.

The external switch connections can operate while the membrane keyboard of the ENC-3300 is still
connected, however only one switch, external or keyboard, can be used at a time.

Lead length between the encoder and the external switches must be kept to a minimum distance of 10
feet. Isolating devices such as relays or opto-isolators can be added by the user for additional isolation
over longer distances.
