MP200 Installation Manual

8.0 Maintenance procedure
Maintenance procedure is useful whenever the installer must open one or more tampering systems of any device,
including CU, to perform operations such as repair, replacement, etc. without generating tampering alarms. In this
condition, also a possible temporary disconnection of one or more serial connections is not generating any tampering
alarms.
To access maintenance, following operations are performed:
- Entering installer code (where installer code is not validated, access has to be made via master code and
installer code has to be validated).
- Within one minute, opening control unit tampering system: no tampering alarm is generated and a start of
maintenance event is created, stored in the historical file and sent via telephone line to the centres (if system on/
off sending is validated, see STM200 manual para. 6.16).
- Remaining in maintenance procedure until control unit tampering system is closed back, or until the last peripheral
tampering system is still open.
- At the time when control unit tampering system input is closed back, or when the last peripheral tampering
system is still open, an end of maintenance event is generated, stored in the historical file and sent via telephone
line to the centres (if system on/off sending is validated, see STM200 manual para. 6.16).
Notes:
It is reminded that during maintenance it is not possible to start the system and, which is more important, it is not
possible to exclude areas; generally, the system is out of service.
Tampering systems open during maintenance are not stored in the historical file but signalled in real time on (S LED)
keyboards without storing the alarms.
