The SRL-1 is a single line loud ringer with built in LEDs. Users can quickly notify employees of incoming calls and visitors with four traditional ringing sounds and doorbell tones, while also flashing the built-in LEDs for added visibility. The SRL-1 will generate loud ringing and bright flashing LEDs from an analog ringing line or from a dry contact closure. There are four different ringing sounds to choose from. The loud ringing is easily adjusted and a test button is included to check the volume. The SRL-1’s unique sounding rings are useful for employees that often work away from their desks, allowing them to instantly recognize when their phone is ringing.
