What it is
Summary
AI-generated from vendor-published content · April 26, 2026
This device wires directly into an existing home or commercial fire alarm panel and transmits a wireless signal to Silent Call Signature Series receivers throughout the building when the alarm activates. It's designed for people who are deaf or hard of hearing and need visual or tactile alerts — like strobe lights or bed shakers — instead of relying on audible fire alarms alone. This transmitter is one piece of a larger alerting system; you'll also need at least one compatible Signature Series 418MHz receiver to actually deliver the alert. Because it requires hardwiring into a fire alarm panel, professional installation by a licensed electrician or fire alarm technician is necessary — this is not a plug-in device.

- Purchase at least one compatible Signature Series 418MHz receiver to complete the alerting system.
- With professional help
