2016S Shumway wiring

M2016S have a relay circuit to disconnect the handset when on-hook (on-hook security), and require an external power supply to function, eg: Shumway SBI-217-25 (42VDC @ 300mA), or PSU. The following shows how the external power supply is connected.

Phone Jack:

The M2016S requires a 6 conductor line cord, the wall jack may be either RJ-12 (6 pin) or RJ-45 (8 pin).

Additional Information:

AC (wall-wart) power supplies are for loops of 30m (100ft) or less. DC power is required for loop lengths of 200m (650ft) or less.
You will hear the 2016's relay "click" when power is correctly applied (with or without TN). A working TN is required for dial-tone!

Configuration of plug-in transformer.

The M2016S red LED triangle will light steadily when off-hook, or ringing (eg, handset/piezo relays are connected) and blink for "message waiting". The M2016S has no handsfree capability, nor does it support any accessories, options, or add-on modules.
