Standard wiring options with LED

Testing the unit

Using the test key provided, insert the key into the test
hole (situated on the bottom right hand side of the glass
cover) and engage into test cam, and turn the key in a
clockwise direction (approx. 100°). This will simulate the
breaking of the glass element. Use the key to reset the
unit by rotating the key in an anti-clockwise direction to
the original position.
MEDC DO NOT recommend forcing the test key
N ote:
further than 100° clockwise or 0° anti-clockwise as
this may lead to premature failure of the test cam.

Operation

The unit is operated by the breaking of the glass. Due to
the design of the unit, there is no need to use a hammer
as the operator is protected from the broken glass by the
vinyl glass label.

Replacement of the glass

To replace the glass after operation of the unit, remove
the small outer cover held in place by the single M3
screw (2.5mm A/F hexagon key). Take out the glass and
remove any broken fragments from the unit. Place the
new glass element into the unit and replace the cover.
Following replacement of the glass it is advised that the
unit is tested using the procedure outlined above.
