The cover must be removed to gain access to the RS232 port at the side of the detector. It must be
replaced for a minimum of 60 minutes prior to flow normalization.
Access Codes
Access to some modes in the Main Menu and other configuration and control functions require the user to
enter an Access Code. There are several levels of access:
1. Operator
2. Level 1
3. Level 2
4. Level 3
Access Code Levels are downwards applicable - for example if a User enters the Level 2 Code, they have
access at the Operator Level and Level 1. The Operator Access Code is changeable as a parameter in
Configuration Mode, which requires Level 1 Access. The default Access Codes are shown below.
Table 4-1: VESDA VFT-15 Detector Access Codes
Access Level Access Code
Operator 0 = not required
Level 1 260
Level 2 693
Level 3 Factory Use Only
How to Enter an Access Code
When entering an Access Code, the alternative function LEDs above the ACCEPT and RESET buttons will
be lit, enabling these buttons to be used as UP and DOWN buttons to enter a 3-digit number.
If the UP or DOWN buttons are continually pressed, the 'units' digit on the Status Display will be activated,
then the 'tens' digit, then the 'hundreds' digit. If the button is released, the flashing digit (units, tens or
hundreds) is the one that will change with further use of the UP and DOWN buttons. When the hundreds digit
is correct, wait about five seconds for the flashing digit to move to the tens digit, then set the tens to the
required value. Repeat for the units digit.
