Door top alarm which helps prevent suicide at the tops of doors.


Tamper proof system detects when weight is applied to the top of the door and has a variable alarmed delay setting between 5 and 30 seconds. The Door Top Alarm connects via mains power and is compatible with most staff attack systems. It can alert staff via audible alarm, visible light, staff indicator panel and via the pager or main computer.

If the top of the alarm is pressed nothing will happen until the programmed delay setting in the electronic box is activated. It has a three-tiered LED system on the door top alarm which is mirrored on the electronic body and optionally on nurse stations. LED lighting shows it working without setting the alarm off, helping with risk assessment period checks. LED is not visible to patients. An inspection magnet is used to aid installation and carry out risk assessments. The electronic box is housed in ceilings/ lofts and connects to the mains power and staff attack system. Power transfer to the door goes via Intastop’s Electrical Transfer Hinge which ensures all cabling and electronics are concealed.

Performance tested to 1.25 million cycles; it has a removable option, where the hinge is designed to be installed in two sections. This allows the current carrying cable to be serviced or replaced without removing the door from the frame.
