Pre-visit checks
¨
Ensure there are accurate as fitted wiring drawings available, 2 copies are required.
¨
Ensure access will be provided to the system equipment installed in the premises.
¨
The installer (electrical contractor) will be in attendance until the installation is
proved.
¨
Site contact or representative will be available during the visit.
¨
Ensure the commissioning tool along with the associated cables and printer, plus
instructions, are available.
¨
Ensure spare parts are available, such as:
•
MCP glasses
•
MCP test key
•
Printer paper roll (for external printer if used)
•
Spare key for equipment cover.
¨
Ensure the system standby duration is to the project requirement and the standby
duration has been checked with the Nano Battery Standby Calculator.
Check with the installer
"
Ensure the maximum cable length between loop devices has not
exceeded 250m. This is the cable distance between previous and next
device on the loop. If the cable length has been exceeded then
rectification action must be taken.
Installation
¨
The system has been installed correctly in accordance with the installation
instructions, respective standards and project specification.
Earth leads
¨
All earth leads supplied with the system equipment to include those supplied with
loop devices are securely fitted to maintain earth continuity.
Loop wiring
¨
All the devices on the loop have been correctly wired, as shown in the installation
instructions and in accordance with the as fitted wiring drawings.
Parts for later installation
¨
Those parts not used during installation have been left in a safe place for use during
system Commissioning.
Points to remember
Unattended equipment
¨
Where equipment is to be left unattended ensure the panel cover is fitted for safety.
Static precautions
¨
The discharge of static electricity can damage or degrade sensitive electronic
components on printed circuit boards. Antistatic procedures should be followed when
handling static sensitive boards.
&
It is important that antistatic procedures are NOT carried out on live equipment.
Panel Buzzer
&
Dangerous voltages exist around the power supply within the panel.
Always ensure the panel is completely powered down before configuring the
buzzer enable / disable link.
¨
It may be necessary during commissioning to switch Off the panel buzzer. There is a
buzzer enable (On) / disable (Off) link on the Main Control Board. It is important to
ensure that the buzzer is switched On for normal operation after commissioning.
Sensor cover
¨
Each fire sensor installed in the system should have been fitted with a dust cover
during installation. The dust covers must be removed from all the fire sensors after the
panel loop has been satisfactorily powered-up and with addresses allocated to each
device ready for further checks and tests during commissioning.
Site specific installation
¨
Plant equipment interfaced to the system should be tested to recommendations made
in the site project specification. These tests are normally left until after the fire system
is configured and tested.
Zone Test mode
¨
During commissioning of the system you will need to enable the 'Zone Test' mode or
'Commission mode'. It is important to disable (Switch Off) the 'Zone Test' mode or
exit the 'Commission mode' after the work is over for normal operation.
Devices
¨
Always install new devices on the loop circuit. Never use devices that have been
previously installed on the loop circuit of another system.
