Bellman & Symfon BE1284-433 Smoke and Fire Alarm Transmitter: Detects fires early and sends instant alerts
For seniors or those with hearing loss living independently, a standard smoke alarm's beep can be missed. This Bellman & Symfon transmitter solves that by connecting to your Visit system, turning a fire alarm into a loud alert, flashing light, or bed shaker you can't ignore.
Think of it as your safety backup. When smoke triggers the alarm, it sends a wireless signal up to 520 feet to paired receivers in other rooms. You might see the strobe light flash from your favorite chair before you even smell smoke. It works without WiFi, so power outages don't stop it, giving peace of mind to families checking in on elderly relatives.
Pair it with Visit receivers for a custom home safety network. It's designed for assisted living or private homes, ensuring reliable emergency alerts that keep everyone connected and secure.
Features
- Wireless alerts with 520ft radio signal range
- Loud alarms and vibration notices for hard of hearing
- Pairs with visit receivers for custom home alarm system
- Emergency safety for seniors and assisted living
