8.2 Unlocking the detector
If the detector is locked, it can be unlocked from the base by inserting a 1.5mm hexagonal driver into
the small hole on the detector face and gently levering the handle of the driver outward whilst
rotating the detector anti-clockwise.
8.3 Non Locking Base Conversion
If the locking mechanism of the Orbis TimeSaver base has been activated in error the base may be
converted to a permanently non-locking base by removing the detector and cutting out the small
portion of the rim marked with a cross-hatch as shown below.
If it is required that all detectors be fitted with their LED
’s facing in the same direction the bases must
be fitted to the ceiling observing the marking on the exterior which indicates the position of the LED.
The bases may be connected as shown in Figure 4 where remote LED
’s, if required, are connected
to the associated base.
When all the bases have been fitted a voltage test for wiring continuity may be carried out. The base
is fitted with a continuity link which automatically opens when a detector is fitted to the base for the
first time. Once satisfied the circuit is wired correctly fit the detectors.

Note: TimeSaver Base LX does not have the continuity link.

Figure 4 also shows how to connect one remote LED to more than one base so that an alarm in any
of the connected detectors will switch the remote LED.
In many installations bases with diodes are specified in order that an active end-of-line device may
be fitted. Diode bases ( see below ) are marked ‘OD’.
