The high visibility combined with a magnetically activated alarm on this alarm door banner by Drive Medical provide an effective deterrent to wandering. An arresting yellow banner and bright red "STOP" sign will catch the patient's eye. The alarm features an "off/soft/loud" switch and LED low-battery indicator. It attaches to the doorjamb with a hook and loop and fits doors from 30" to 42" wide. Requires two AAA batteries, which are sold separately.
