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 faster and more reliable in-
stallation. The sounder head ‘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 sounder to the base can be activated
by removing the thin section of plastic shown in Fig. 1 with side cutters or a
similar tool. To open a locked head, remove the small rubber bung from the hole
on the side of the sounder, 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 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 com-
petent and qualified personnel.
