Orbis IS Base
®
installing rbis IS
Orbis IS has been designed to make installation fast
and simple. Fig 4 shows the TimeSaver Base as it is
seen from the installer’s point of view.
The E-Z fit fixing holes are shaped to allow a simple
three-step mounting procedure:
• Fit two screws to the mounting box or surface
• Place the Orbis IS base over the screws and slide
home
• Tighten the screws
The base offers three fixing centres at 51, 60 and 72mm.
A guide on the base interior indicates the length of
cable to be stripped. Five terminals are provided for
the cables, four being grouped together for ease of
termination.
The terminals are:
• positive IN
• positive OUT
• negative IN and OUT (common terminal)
• remote LED negative connection
• functional earth (screen)
The terminal screws are captive screws and will not
fall out of the terminals. The base is supplied with the
screws unscrewed in order to avoid unnecessary work
for the installer.
The end-of-line resistor should be connected between
the OUT+ and COM– terminals.
If it is required that all detectors be fitted with their LEDs
facing 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 Fig 5 where
remote LEDs, if required, are connected to the associated
base.
Fig 6 shows how to connect one remote LED to more
than one base so that an alarm in any of the detectors
connected will switch the remote LED.

fitting rbis detect r heads
When the bases have been installed and the system
wiring tested, the detector circuits can be populated.
Two methods are suggested:
1. Apply power and fit the detectors one by one,
starting at the base nearest the panel and working
towards the end of the circuit. As each detector is
powered up it will enter ‘StartUp’ and flash red (see
Table 1 on page 14). If the LED does not flash,
check the wiring polarity on the base and ensure
there is power across IN+ and COM–. If the LED is
flashing yellow the detector is not operating correctly
and may require maintenance or replacing (see
DirtAlert and SensAlert®below and the section
‘Servicing’ on page 18).
2. Fit all detectors to the circuit, apply power and
check detectors by observing the LED status of each
device. The StartUp feature lasts for 4 minutes so it
may be necessary to reset or de-power the circuit to
allow all detectors to be observed. The LED status is
the same as method 1.

Note: the earth terminal in the base is provided for convenience where
continuity of a cable sheath or similar is required. It is not necessary for the
correct operation of the detector nor is it provided as a termination point for a
safety earth.
If screened cable is used screen continuity should be maintained and the
screen should be earthed only at one point. The earthing point should
preferably be close to the safety barrier.
The system complies with the requirements of the CPD only if wired using
screened cable. For details of cable connections see BSEN60079–14, section
12.2.2.
