6.5.3 Write Protecting / Locking
The E3 MODULEVEL transmitter is password protected
with a numerical value between 0 and 255. After the pass-
word has been successfully entered, an exclamation mark (!)
appears as the last character on the first line of the display.
Refer to the E3 MODULEVEL Installation and Operating
Manual (Bulletin 48-635) for information on password pro-
tection.
NOTE: Default Password = 0 = Password disabled.
For an SIS system, it is required that, after configuration of
the system is complete, a password is utilized to prevent
inadvertent changes to the device.
6.6 Site Acceptance Testing
To ensure proper operation after installation and configura-
tion, a site acceptance test should be completed. This
procedure is identical to the Proof Test Procedure described
in Section 7.1.4.
6.7 Recording Results
Results of Site Acceptance Testing must be recorded for
future reference.
6.8 Maintenance
The only maintenance required is the proof test.
