GENERAL HANDBOOK FOR HEIMDALL

DETECTORS

Doc. No. 667/HB/31900/000

4.5 Electrical Connections – UK Variant

4.5.1 General

All Heimdall detectors are equipped with a captive lead and standard 9 pin ‘Buccaneer’

connector (see Figure 7).

Figure 7 – Buccaneer Bulkhead Connector (Front View)

The wires from this connector should be terminated in accordance with the details shown

in sections below.

Note 1: Particular attention should be paid to the correct termination of the power

supply wires. The RED wire should be used for the POSITIVE AC/DC supply feed

and the Black wire for the NEGATIVE supply return.

Note 2: When installing this detector with a 24 AC source, please ensure the 24 AC

source is derived from an earthed secondary transformer (as used in standard

traffic installations).

Note 3: When using 24 AC supply, only use battery powered interface equipment

(e.g. laptop, PDA). Do not connect mains powered/connected interface equipment

to the Heimdall series of detectors, as this will cause the detector’s fuse to fail.

Note 4: When installing this detector with a Siemens ELV controller or a Siemens

ELV controller additional supply, please ensure the RED wire of the interface cable

is connected to the POSITIVE (common) connector, the BLACK wire is connected

to the NEGATIVE (-24VDC) source and the GREEN (screen), if included, is

connected to the POSITIVE (common) connector.
