Silent Call DB1-SS Wired Doorbell Transmitter 418mhz

Product Description

The SILENT CALL DB1-SS is a wired doorbell transmitter operating at 418 MHz, designed to integrate a standard wired doorbell button into a SILENT CALL wireless alerting system. When the doorbell button is pressed, the transmitter sends a 418 MHz radio frequency signal to compatible receivers or alert devices throughout the coverage area. This unit is sold individually and is well suited for installation by low-voltage technicians, alarm and life-safety professionals, or qualified electricians working on assistive notification and fire accessory systems.

The DB1-SS is intended for residential and light commercial applications where a wired doorbell must be connected to a wireless notification system. It is particularly common in assistive listening and alerting environments where visual or vibrating receivers are used to notify occupants who are deaf, hard of hearing, or otherwise require alternative alert methods. The transmitter bridges existing wired doorbell wiring to a wireless RF network without requiring a full system rewire.
