Along with a pool barrier and swimming instruction for your child, a pool alarm is an essential component of any pool safety plan. Be prepared and armed with the PoolEye Immersion Pool Alarm. The PoolEye PE23 pool alarm is certified to A.S.T.M. standard F2208, which meets or exceeds virtually all pool safety inspection standards. The alarm is designed to fit the vast majority of inground pools and aboveground pools with a top rail. For recommended installation guidelines for larger pools or those with different configurations please see the manual under the Product guides and documents section below the Product information section. The pool safety alarm features sub-surface wave detection, so there are fewer false alarms. The 85 dB siren alerts when an object as light as 15 lb/7 kg is detected. A magnetic key is included for reactivating/resetting the alarm. An in-home remote alarm is also included, so you will immediately be alerted whether you are indoors or out. PoolEye is the only brand you need to give your family peace of mind when it comes to pool safety.
