a It is necessary to have regular and timely maintenance checks performed in order to secure reliable
functioning of the system. Most of the maintenance is carried out by an installation company at least once
a year during periodical maintenance inspections.
a User maintenance consists mainly of keeping the individual devices clean. The ADMINISTRATOR
of the system can switch se system to a MAINTENANCE mode in order to be able to open the detectors
(change batteries) or to remove them from the installation. Consult the request to set the MAINTENANCE
mode with the installation company. If the system is configured to the “EN 50131-1, grade 2” system profile,
the MAINTENANCE mode is not available.
a The system can be switched to the maintenance mode via the J-Link software or from the menu of the keypad
with LCD display. After authorization a “Maintenance mode” can be selected with a selection of sections
where the maintenance is needed. In the maintenance mode no alarms will be triggered in the selected
sections, including opening or removing the detectors from the installation.
a The maintenance mode is indicated by the activation button flashing green (2 flashes each 2 seconds) and
by the two segment buttons of the particular section lighting off.
a When handling with the devices a care must be taken to avoid damage to the plastic and mechanisms
of the detectors.
a The cover is usually secured with a tab that needs to me slightly pushed into the detector’s body with a small
tool (e.g. screwdriver) and then the cover can be taken off. In some cases, the tab is secured with a small
locking screw that must be unscrewed first.
a When changing batteries in the detector, always replace all batteries in the particular detector at the same
time (use batteries of the same type and from the same manufacturer).
a Some devices may require testing (e.g. fire detectors). For more information please contact your service
technician.
