– The detector box and sensor tube (SENSTUBE) must not be installed in a location
where they are exposed to direct sunlight.
– Fit the detector box inside a protective box when installing it outside or in a tunnel.
– The detector box can be mounted anywhere, although it must be a minimum dis-
tance of 0.1 m from switching boxes, recesses etc. on the sensor tube connection
side.
– The permissible sensor tube length is between 20 m and 80 m [min - max].
Larger lengths require the manufacturer's approval.
– The sensor tube must be fixed in place using metal pipe clips when used in areas
with higher ambient temperatures.
– It can be installed to the underside of cable ducts as long as the distance to the ceil-
ing is not greater than 0.5 m.
– The sensor tube should not be installed adjacent to, below or above strip lighting. If
this is unavoidable, make sure a minimum distance of 0.5 m is adhered to.
– At tunnel entrance portals, a distance of 25 m must be maintained between the sen-
sor tube end and the portal.
– The sensor tube should preferably be mounted in the center of the tunnel ceiling
(max. permissible side tolerance ± 0.5 m).
– Minimum distance (1) to tunnel walls must also be ensured:
– For 2 traffic lanes: 1 > 0.5 m
– For 3 traffic lanes: 2 > 1.0 m
– The maximum permitted sensor tube length is 130 m.
SENSTUBE
– At least two sensor tubes are required; this will therefore also require more detector
boxes as only one tube can be fitted to each detector box.
– Maximum permissible distance (1) between the sensor tubes is 10 m.
– Maximum permissible distance (2) between sensor tube and tunnel wall is 5 m.
