4.15. Connection requirements

Electricity and voltage limiting measures must be implemented in the superior system for the supply as well
as for the fault report interface. This ensures that the contact temperatures do not reach the welding temper-
atures of the alarm contacts.

4.16. Warning

WARNING Detriment to sight
In order to prevent detriment to sight, continuously looking directly in the activated light is to
be avoided.
DANGER Danger of electric shock!
Before all work on equipment, the following should be observed: switch off the equipment
before opening. Wait 5 minutes before opening the housing. Approx. 320 V are in the flash
capacitor when in use. All work on the equipment is only to be carried out by authorised
technical personnel

4.17. Maintenance advice

The light is largely maintenance-free. However, the 'proof test' interval should be observed and the lifetime of
the flashtubes are not to be exceeded.
In an environment where extensive dirt or dust is to be expected a regular cleaning of the exterior surface of
the light emission is recommended. The hood made of polycarbonate can only be cleaned with water or rins-
ing agents.
Changes, modifications, faulty and incorrect use as well as not observing the advice of this operating manual
void the warranty.
