2.1 Introduction
Commissioning of the Medipoint 125 medical gas central alarm installation is
carried out in full after initial installation and the appropriate sections must be
carried out after a major component change. The object of commissioning
is to ensure that all components are serviceable and correctly programmed.
The commissioning procedure also ensures that anti-confusion checks are
carried out and that the correct gas service is displayed in the designated
column. Personnel carrying out the following commissioning procedure must
be qualified and fully conversant with the information contained in this
manual.
WARNING…
BEFORE COMMENCING THE COMMISSIONING PROCEDURE ENSURE THAT ALL
INSTALLATION PROCEDURES ARE COMPLETE AND THAT ALL WIRING IS
CORRECTLY CONNECTED. BEFORE SWITCHING ON THE MAINS ELECTRICAL
POWER SUPPLY, ENSURE THE SUPPLY IS CORRECTLY FUSED.
2.2 Functional tests
When all alarm panels have been installed and connected, the following
functional checks must be carried out on every alarm panel in the systems.
Commence the procedure at alarm panels which receive an input and
progress until all ‘input’ panels are proven. Carry out the procedure on the
‘central’ panel(s). Repeat the procedure on all ‘repeater’ panels including
those previously checked as input panels, Ensure that all gas service displays
and all alarm panels are proven.
2.3 Alarm panel. Check internal connections.
Check the multi-way ribbon cable is correctly connected.
2.4 Electrical power supply. Switch ON.
Switch ON electrical power supply to alarm panel. Check that the POWER ON
LED illuminates.
2.5 Alarm panel. Test.
Press the TEST switch and check that all the alarm panels LED’s illuminate
(flashing) and the audible warning sounds.
2.6 Gas service. Check alarm conditions.
Taking each gas service in turn, ensure that the NORMAL indication is
illuminated in the correct display column on all panels displaying that gas
service, when the gas service is set to work normally. Set the gas service to
introduce the 1st, 2nd, 3rd and 4th alarm conditions and ensure that the
correct alarm light illuminates in each case. Throughout the procedure,
ensure that the LED’s are the correct colour and gas service legends are
correct and in accordance with the correct specification. This check must be
carried out on all panels displaying that particular gas service.
2.7 Audible warning. Check.
Whilst carrying out Step 2.2.4, ensure that audible warning sounds for the
appropriate alarm conditions. Ensure the operation of the MUTE switch
cancels the audible and that the audible comes on again after
approximately 15 minutes.
2.8 Remote audible. Check.
Check that all remote audibles operate whenever there is an alarm condition
on it’s parent panel. Check that the remote audible is silenced by operation
of the MUTE switch on parent panel.
2.9 Relay interface panel. Check
If a relay interface panel is used with the alarm system, it’s operation must be
checked whilst checking each gas service status applicable to the panel
(Step 2.2.4). With a gas service operating ‘normally’ the appropriate relay
should be energised and it’s ‘normally open’ contacts should be closed.
