5.0 Panel Configuration – Engineer’s Operating Instructions
NOTE: Please read the panel configuration options before proceeding to commissioning.
5.1 Introduction
The functions are intended to allow a complete system to be set up at site level. Three levels of
engineer functions are provided. The access system is arranged such that level 1 access only is
possible with code 1, levels 1 & 2 with code 2 and all levels with code 3. Level 1 functions are
intended for the end user. When the engineer functions are selected, the control panel in most
cases still fully operational i.e. an alarm condition will fully activate the panel. The only
options which cause the panel not to be fully operational are described later under “Status -
disabled” and “Sensor test”.
All engineering menu functions are available after operating the ACCESS CONTROLS key
switch and then pressing ENGINEER on the display, followed by input of the appropriate four-
digit access code.
If system is left in the engineers mode without controls being pressed, the panel will “time out”
to normal operation. Time-out periods vary, depending upon option selected, from 1 to 15
minutes.
