ADS Environmental Services Model 3600 530002 A2 - Manual (Page 105)

Monitor Maintenance 6-3
As discussed in Chapter 1, “Maintenance Restrictions,” IS monitors must be
maintained by an ADS IS certified technician. If an ADS IS certified technician is not
available locally to replace the battery, the IS monitors must be sent to ADS for
battery replacement. In order to preserve its IS certification, a 3600 housing cannot
be opened by anyone other than an ADS Service Technician. Opening the monitor
housing will immediately void its IS status.
If you have any questions regarding the level of service you are allowed to perform on
a monitor, refer to Chapter 1 or contact your regional ADS office.
Lightning Protection Module
If a lightning protection module is installed at the phone pedestal, check it for lightning
strikes. If the lightning protection module has burned out, replace it with a new one
and send the old one to ADS Environmental Services, Inc., for repair.
Telephone Interface Box
If you have any problems with the telephone interface box, check the connectors to
ensure that the cable entries are tight and waterproof. If this does not solve the
problem, replace the telephone interface box with a new one and send the old one to
ADS Environmental Services, Inc., where an ADS IS certified technician will repair it.
If anyone other than an ADS IS certified technician repairs this box, IS certification
will be lost.
EMU
The EMU may be internally or externally powered. Maintenance for each type of
EMU varies.
Internally Powered
If the EMU uses internal batteries, check that the monitor is not reporting low modem
batteries in the EMU. Also, check that any cable entries are tight and waterproof and
ensure that the lid of the EMU is tight.
Externally Powered
If the EMU uses an external power source, ensure the earth ground is connected.
Also, check that any cable entries are tight and waterproof and ensure that the lid of
the EMU is tight.
