Mounting The Unit; Wall Mounting Of Dräger Polytron Pulsar 2 With Eex E Junction Box - Dräger Polytron Pulsar 2 Technical Manual

Installation of a Dräger Polytron Pulsar 2

Mounting the unit

The Dräger Polytron Pulsar 2 should be mounted to a stable structure free of excessive vibration. Good choices would be a steel bulk-
head, brick wall, concrete lamppost or a rigid steel structure. Avoid flimsy metal structures that may flex, or wooden structures that may
warp. In open areas a suitable structure close to the ground would consist of a five inch nominal (141mm outside diameter) steel pipe
driven 1 metre into firm ground or embedded into a concrete foundation. Tall structures should be suitably guyed or braced.
