836 / 936 Amplifier/Power Supply

The Alpha Communications® 836 / 936 amplifier/power supplies are used with the 142 / 142A series switchboard intercom systems, to provide intercom amplification, call up and call down signaling and power to light the 142142A lamps. 

The 836 / 936 units each require a standard 120VAC power source.

These 836 / 936 amplifier/power supplies are designed to easily surface mount right onto the finished wall by means of customer supplied screws. Connections are positive screw terminal type.

Only one (1) 836 / 936 is required for each system, regardless of the number of handsets (1 per apt.). The current model is the 836, but it will very shortly be replaced by the model 936.
