SF339 Emergency Push Station

The Alpha Communications® SF339 Emergency Push Station includes a locking Mushroom-Style switch, and is used in any area where activation of an emergency station is required. All electronic components are mounted on a circuit board, including a reliable industry-proven DPDT switch for circuit initiation. The DPDT switch and the indicator LED are completely sealed in plastic.

The SF339 may be used as an emergency station or as a staffassist emergency call station. The large mushroom-style button is easily activated, so that calls may be placed using an elbow, shoulder, etc., when using the hands is inconvenient or inappropriate. Calls are cancelled by turning the mushroom-style button clockwise.

Dome light and system annunciation vary according to the manner in which the SF339 is connected, and which system it is used with.

The SF339 is typically used with the HC345C, NC205, NC110A, NC110N, NC150N, NC150R, NC200N and NC300 systems.

The SF339 is not designed for use in a shower or 'moist' environment(s).
