Replacement of the glass:
To replace the glass after operation of the unit, remove the small cover held in place by the 2 slotted screws. Take
out the glass and remove any broken fragments from the unit. Place the new glass into the unit and replace the
e
cover, then test the unit as described below.
Testing the unit:
Using the test key provided, insert the key into the test hole (situated on bottom right hand side of the glass
cover) and engage into test cam. Turn the key in a clockwise direction (approx. 60°). This will simulate the
breaking of the glass. Release the key to reset the callpoint.
NOTE: MEDC DO NOT recommend forcing the test key further than 80° clockwise or 0° anti-clockwise as
this may lead to premature failure of the test cam.
