11. Maintenance and service

For maintenance and inspection work on danger detector systems, in Germany

the regulations of DIN VDE 0833 apply, which refer to the maintenance interval

according to the manufacturer’s instructions.

D Maintenance and inspection work should be carried out regularly and by trained

personnel.

D BOSCH ST recommends a functional and visual inspection at least once a year.

D Multisensor detectors with C--sensors must be exchanged every 5 years.

. OTC 410 L SN / OC 410 L SN:

Depending on the lifespan of the gas sensor, the detector OTC 410 LSN and OC

410LSN switches the C--sensors off after 5 years of operation. On the central unit,

the detector in question is displayed with “EMERGENCY OPERATION” and it

continues to function as an OT or O detector.

The detector should be exchanged immediately in order to be able to keep using

the higher detection security of the OTC and OC.

. OC 310 GLT:

Depending on the lifespan of the gas sensor, with the OC 310 GLT the C--sensor

is switched off after approximately 5 years of operation; the detector continues to

function as an O detector.

Depending on the system, there is no report to the centr al unit and the switching--off

of the C unit is only noticed when the detectors are tested. Therefore the OC 310

should be exchanged in timely fashion before 5 years of operation have e lapsed.

D Optical fire detectors (smoke detectors) should, depending on the

environmental conditions, b e cleaned and exchanged every 4 -- 6 years.

. In especial ly dusty environments, cleaning and exchange may be necessary earlier!
