Installation and Commissioning
Installation 1
st
Stage
The installer must install the system wiring in the form of 2-core radial circuits. The cabling should be 2
core 1.5mm
2
, screened and fire resistant, of an MICC or FP200 equivalent type. 4 core cable as a zone
in and zone out must not be used, due to the possibility of data corruption.
The zone should be left unconnected to the panel with no devices installed and must be tested for
continuity and integrity with a multi-meter set to read Ohms.
The control panel back box should be mounted, with the mains supply tested, connected and isolated at
the un-switched fused spur, ready for commissioning. Where the zone cabling is continued via the
device, the cables should be temporarily connected through using connector blocks.
The installer needs to provide a set of ‘As-Wired’ drawings and proof of loop continuity and insulation
test readings etc. before commissioning may proceed. This information is essential, and may be
entered onto the forms provided at the rear of this manual.

nd
Stage
Once the commissioning engineer is satisfied with the continuity / integrity of the zone cables, the
control panel may be powered up as follows:
1.
Ensure that none of the field wiring is connected to the panel. This is not essential but
it helps to build up the system in sections when commissioning a system for the first
time.
2.
Apply the 230V AC mains supply, before connecting the batteries.
3. The control panel takes approximately half a minute to boot up its processor.
4.
Program the number of active zones required, and any other settings needed. This is
easier and quicker using a laptop PC and the TWINFLEX
®
SRP OSP software via the
USB port.
5.
Add a device to the end of each zone and ensure that the EOL signal is switched on in
all these devices. Connect the zones into the control panel one at a time and ensure
that the fault lights clear as each zone is connected (after approximately. 20 sec).
6.
Add the additional devices in one at a time. In the case of detectors, allow each one to
clear from fault (approximately half a minute).
7.
Connect all other circuits and ensure that they are fault free.
There is no requirement to build the system up in sections in this manner, but we recommend this
method as good engineering practice to provide a controlled process of building up the system in
blocks.
