Specifications

What to do first
The portable signal controller and detector equipment must be of a type approved on behalf of the
Secretary of State for Transport. Specifications are issued by the Highways Agency.
Look on the controller for a label* for the specification reference. Most equipment will be approved
against MCE 0111, TR 0111, or the current TR 2502. Equipment to MCE 0111 and TR 0111 has the
same initial set-up (see pages 15 and 16), whereas that to TR 2502 is different. This booklet gives advice
on both initial set-up sequences. For ease of reference, the sequence of
MCE 0111 and TR 0111
will
be highlighted in pink and that of
TR 2502
in yellow. In addition, there is one controller approved to an
interim specification 027-008-024. References to 027-008-024 have been made separately.
Look on the detector housing for a label* stating which specification
applies. Equipment is approved against MCE 0114 (C), TR 2147, or
the current TR 2504. The detector housing may be fixed to the top
of the signal head; others are fitted below the head.
If the relevant controller/detection specification information is
not on a label, it may be on information in the controller housing.
However, if the specification information is not available, you
or your supervisor should check with the traffic authority that it
is approved.
*Note: There is no longer a requirement for the label to bear a crown emblem.
