Make any built-in fire alarm a visual notification system for the Deaf and hard-of-hearing. This KA300 system is an emergency alerting system used as a bridge to transmit audible signals from an existing built-in fire alarm to the sound and strobe receiver in the guest room. The KA300 connects up to three built-in audible emergency alarms such as fire, smoke, carbon monoxide, weather alerts, and Vessel General Alarm into one monitoring system. When activated anywhere in the building, the transmitter sends a wireless signal to the sound and strobe receiver to notify your guest of an emergency. The system installs in minute with tool-free installation, without the cost of rewiring the building.
