Yes — Florida rule 64E-9.008 requires a fixed emergency telephone at the pool that dials 911 directly, with no coins or codes needed.
Florida requires an emergency telephone accessible to the pool area. It must be affixed in place and capable of dialing 911 without needing coins or an access code.
Citation: 64E-9.008
The "no coins or codes" language is important: a phone that requires a PIN, an outside-line code, or coin insertion does not meet the standard. Direct-dial cellular emergency phones are a straightforward way to satisfy this in Florida.
SouthEast Telephone installs and monitors cellular emergency pool phones nationwide and can help you meet Florida's requirements.
