The model SF-117 Emergency Call Switch is a rugged, longlife, positive acting switch mounted on a durable ABS plasic faceplate. Signaling an emergency requires just a short pull on the 6' long nylon cord, in any direction. The signal cannot be cancelled except at the point of origin.

The SF-117 provides two circuits to operate one or two signaling devices, such as a remote annunciator lamp, and a corridor dome lamp.

A unique feature of the call switch is that it has a mechanical indicator window that turns "RED" when the call switch is activated. This provides a "Call Placed" Capability without the need for any lamp indicators, additional power supplies, or additional wiring.

The SF-117 emergency call switch is silk-screened "EMERGENCY" in black.
