5.0 Installation
The TimeSaver base enables quick and easy installation of these units with no
extra cabling to be made to the head of the unit. Connections are made to the
base during the initial wiring phase which results in a faster and more reliable
installation. The head unit ‘twists and clicks’ into the base on commissioning,
thus avoiding any wiring and connection problems associated with traditional
installations.
If required, the mechanism for locking the head unit to the base can be acti-
vated by removing the thin section of plastic shown in Fig. 1 with side cutters
or similar tool. To open a locked head, remove the small rubber bung from the
hole on the side of the head unit, insert a tool into the hole and depress the clip
whilst twisting the head.
An alternative locking method is shown in Fig. 1b. Drive the hexagonal locking
screw forward by turning a 1.5mm hexagonal key clockwise until the head is
locked.
The O-ring and bung must be re-fitted to maintain the weatherproofing.
General Requirement
The Sounder-Beacon must be installed in accordance with the latest EN60079-
0 specification or equivalent IEC specification. With consideration for any
local installation requirements and should only be carried out by appropriately
competent and qualified personnel.
