Installation and Commissioning
Installation 1
st
Stage
The installer needs to install the system wiring in the form of a 2-core radial circuits. The cabling should be
2 core 1.5mm
2
, screened and fire resistant, of an MICC or FP200 equivalent type. We recommend against
the use of a 4 core cable as a zone feed and return, due to the possibility of data corruption.
The zone should be left with no devices connected, and must be tested for continuity and integrity with a
high voltage tester, as required for general electrical installations.
The control panel back box should be mounted, with the mains supply tested, connected and isolated at
the un-switched fused spur, ready for the commissioning.
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 the manual.
Installation 2
nd
Stage
Once the commissioning engineer is satisfied with the continuity / integrity of the loop, the control panel
may be powered up as follow.
1. Ensure that none of the field wiring is connected. 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. When
this is complete the empty zones should all indicate a fault. This is correct.
4. Program the number of active zone required, and any other settings needed.
5. Add the last device on to each zone, ensuring that its EOL signal is switched on.
Connect the zones into the control panel and ensure that the fault lights clear as each
zone is connected.
6. Add the additional devices in one at a time, allowing 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 need directly 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.
Commissioning
Commissioning the Twinflex system involves programming and testing the system for correct operation.
It is essential that every device is tested in every mode of operation, and that all programmed actions are
observed for correct operation. This includes the smoke testing of smoke detectors, heat testing of heat
detectors, testing of Manual Call Points, testing of all inputs, testing of all sounders and outputs, and fault
testing of detectors by head removal.
