The Posey Door Guard and Do Not Enter Alarm are effective components for a facility, or home fall and wander prevention program. The Alarm sounds one of five tones when the 53''Guard/Banner is detached from the monitor. The easy-to-install Banner adjusts to fit most facility and residential doorways. When the banner is not in use, the monitor can be easily converted for individual clip and magnet operation. The 95dB Alarm meets OSHA requirements and the volume can be lowered using the included sound-dampening plug. Uses one 9V battery (included).
