3. IFG Functionality
3.1 Introduction
This chapter covers some of the distinctions between AutroSafe
functionality for Oil and Gas panels and standard AutroSafe panels.
3.2 Inhibit Point
All loop input units can be inhibited. When one or several points are
inhibited, the point(s) will not signal alarm to outputs. An inhibited
point will however present an alarm, prealarm and early warning on all
panels and AutroCom as usual. This includes panel buzzer, panel
LEDs and panel LCD display.
It is only possible to inhibit a unit from the panel menu or via
AutroCom. An inhibited point will be inhibited until the unit is un-
inhibited by a manual operation or by timeout.
3.3 Set Alarm Limits
By using the Set Alarm Limits (via the menu) is possible to change a
gas detector’s alarm limit for Low Alarm and High Alarm.
3.4 Get Measurement Values
By using the Get Measurement Values (via the menu) it is possible to
get analogue measurement values for a selected gas detector.
Analogue values can be monitored on the panel or on the AutroOS.
