10. Fail Safe
The Door Top Alarm includes a failsafe system, where the alarm will sound if there is a power
cut or a wire breakage. NOTE - this is only applicable if the staff attack system has been
wired into the Normally Closed terminals in the Hipac electronics box. It is possible to get
notification if the Normally Open terminals have to be used but this will not be an audible
alarm and is dependent on your staff attack company being able to send a failure message
back to say the main control panel at the nurses’ station.
The hinge is supplied in 2 pieces, the main section of the hinge which takes most of the
doors weight and the electrically modified section, at the top, which has the cables running
through it. The reason for this is for ease of service, so if at any time there is a problem, the
electrically modified piece can simply be taken out without having to take the door off.
The wiring to the electronics box should be checked (and signed off at each stage on
the supplied sign off sheet) with the tester box at each stage during installation by the
contractor.
