4) Alarms must be installed at least 54 inches above the floor and be mounted to the door/wall so that it cannot be easily removed.

5) Alarms must have a manual means to temporarily deactivate for a single opening.

6) Alarms can be battery powered or connected to the permanent electrical wiring system.

7) An additional “Pre-Plaster/Safety Inspection” is required for all pool/spa construction projects. In order to pass this inspection, all door/window alarms, window opening control devices, permanent fencing, and self-closing gates must be installed and found to function properly.  Motorized gates (electrical or solar) are not considered to be an acceptable self-closing mechanism.
