13. Trouble Shooting Guide
Please Note: This guide is intended to help you di
agnose a fault on the door top alarm, it may not
tell you how to repair it.
In normal operation the Door top alarm should remain passive until the bar on the top is
activated.
To test the alarm is working properly, you will need a magnet
Begin by closing the door and re-opening it.
• Without pressing on th bar put a magnet to the LED on the leading edge of the door. The
LED should remain clear and unilluminated.
If at this point the LED is presenting green then the fitting of the door is wrong and the DTA
is clashing with the frame causing it to activate. This can be fixed by wither channeling the
DTA deeper into the door or by slightly dropping the hinge.
In this case Hipac do not need to
attend site.
• If when the door is first opened, the magnet remains clear then quickly press and release
the bar once (Keeping the magnet next to the LED). The LED should turn green. This
signals that you have power to the DTA.
If once pressed and released the LED doesn’t illuminate, then there is a power supply issue
somewhere on the circuit. The DTA control box should be located in the ceiling or a cupboard.
On the front of this is a red power LED, this should be illuminated. It this is not lit then there
is an issue with your power supply to thee box.
In this case Hipac should not need to attend
site.
If the red LED is lit up but the LED on the DTA is not illuminating then there is an issue
between the control box and the DTA. Please ensure that the cables at the back of the hinge
and the DTA are both connected as they should be. If they are both connected correctly and
the LED on the box is lit, the
Hipac may need to attend site.
If the LED does illuminate but the light is flashing or no a solid display in anyway, you may
need to check your power supply is running off DC and not AC.
Hipac do not need to attend
site.
• If the LED did illuminate Green, then whilst it is still displaying green the quickly press and
release it once again. The LED should momentarily change from green to orange. Once
the bar is released the LED will change back to green. All the time you are doing this, the
magnet should be kept next to the LED.
If the LED stays orange once you have released the bar then the micro switches may be over
sensitive and will need adjusting. You can test this by rolling the bar to the side and seeing if
