Preventive maintenance
Preventive maintenance is divided into the following categories:
• Daily checks
• Weekly maintenance
• Quarterly maintenance
The daily and weekly maintenance tasks require no technical expertise and
should be carried out by the panel operator.
Daily
The ECU must remain clean at all times. Perform the following:
• Clean the outer surface of the unit to remove any excess dust using a damp
cloth.
• Check for correct and smooth operation of the key switches. Lubricate sticky
key switches if required using 2 or 3 drops of a general purpose lubricant (for
example 3 in 1 oil).
Weekly
• Check any reports sent from the ECU to the fire alarm control panel. Under
normal conditions no abnormal reports should be detected.
• Check the front panel of the ECU and any status units. Only the POWER ON
and Automatic/Manual LEDs should be illuminated.
• Test the function of the Automatic/Manual key switch by operating the switch.
Check that the printer (if available) on the fire alarm control panel indicates
the change in switch position.
• Restore the system to previous configuration.
• Log the test in the system log.
Quarterly maintenance
Quarterly maintenance must be carried out by suitably trained personnel. Such
personnel may be direct employees of the company, or may be contracted from
the maintenance company responsible for servicing.
Quarterly maintenance is designed to pre-empt any problems that may arise and
to check that the system is functioning to its installation specifications. The
services should be arranged through a maintenance contract with a servicing
company. This agreement should specify how to contact the service company
and how they can access the premises.
Repair services should be available within 24 hours. For premises in continuous
use, an engineer should be on call at all times. The servicing company should
have engineers trained in servicing Ziton equipment. The owner of the fire alarm
system is responsible for ensuring that the company contracted is competent to
carry out the work.
