Overview
The RF3503E is a wireless, two-button transmitter that
sends a medical or panic alarm signal to your
monitoring system. Each RF3503E is programmed with
a unique code that allows your monitoring system to
recognize individual transmitters.
Although the range of the transmitter can be up to
100 m in open air, typical building materials can greatly
reduce the range of your unit. It is recommended that
you try out your transmitter at various locations in the
monitored area to test the range.
