R1 Buzzer Pulsator Unit

The Alpha Communications®/S.T.R.™ R1 buzzer pulsator units are used primarily with the S.T.R.™ handset type entry intercom systems, to provide a pulsating buzzer signal from the apartment's individual entry door pushbutton.

The R1 unit works in conjunction with the system amplifier (models NH200A, NH200TV, NH201TVA, NH201TVA-2and NH201TT), and produce a pulsating buzzer sound at the apartment handset, using the same buzzer that is used to produce a signal from the lobby entry station.

These R1 buzzer pulsating units are designed to easily surface mount right onto the finished wall by means of customer supplied screws or the convenient plastic 'Din Rail' bracket supplied with each power supply. Connections are positive screw terminal type.

Only one (1) R1 is used for each system, and no additional transformer or power supply is required.
