AliMed® Basic Pull-Pin Alarm is the most economical way to signal staff that a patient is about to wander. Secure the alarm unit to a chair or bed with its self-contained clip or with the included hook-and-loop fastener. Then simply clip the adjustable 18" to 36" activation cord to the patient's clothing. If the user gets up, the pin connector pulls from the top of unit, and the alarm is activated. To deactivate the alarm, replace the pin or use the on/off switch. Features two tone/volume settings. Requires 9V battery (not included - see Related Products).
