GASEOUS FIRE EXTINGUISHING
6.2.1
GENERAL
The following features of the F3200 make it well suited to gaseous fire extinguishing
applications as required by AS4214:2002.
AZC Alarm Text for "pressure switch", "manual", can be used for the various inputs;
Zones can be programmed as latch/non-latch, MAF/non-MAF as required, e.g. non-latch,
non-MAF, for "Gas Inhibit" input;
Zone range operand allows easy programming of "voting systems" on detector circuits
e.g. 2 out of 3;
Open collector O/Ps can be programmed to drive LEDs such as "Gas Initiated", "Gas
Inhibited", etc;
Programmable timers included as standard (0-250 sec);
Programmable relays, with supervision option;
Operation not fixed by hardware, as virtually any required logic equation for outputs
(using AND, OR, NOT, XOR) can be entered;
Fuse protected battery-backed supplies available via 2A fuse and 6A fuse;
Standard hinged, screened 7U Gas control doors available complete with LEDs,
switches and looms for 1, 2, 3, 4 Gas Zones (Part Number ME0438 to ME0441
respectively);
Standard non-hinged, screened 1U Panel as per above for 1 Gas Zone (Part Number
ME0442);
Standard Local Control Stations (LCSs) and AVI warning signs available. (LCS includes
"Gas Start", "Gas Inhibit" switches, status LEDs). AVIs include selectable Alert and Evac
tones and can be ordered with lettering such as FIRE ALARM / DO NOT ENTER, etc.
Two standard F3200 panels are available factory-fitted and programmed for gaseous fire
extinguishing applications.
FP0876 FP F3200 AS4428 FIP 8U CAB 3A1U GAS CTRL PRE PROG
FP0877 FP F3200 AS4428 FIP STD CAB 6A 1U GAS CTL PRE PROG
FP0876 is an F3200 assembled into the 8U cabinet (FP0784). It comes complete with the
ME0442 1 zone 1U gas control module and an 8 Relay Module. It has a 3A power supply.
FP0877 is based on a 6A (PSU) F3200 assembled in the standard 15U cabinet (FP0782). It
comes complete with an ME0442 1 zone 1U gas control module pre-wired to the 8 Zone
Module and an 8 Relay Module.
The gas control doors (ME0438-ME0442) are wired to provide 2-wire connections to the AVI
Mk2s. Drawings 1931-123 and 1931-124 show how these are wired to F3200 and the
external devices: AVI MK2, LCS, etc.
Special factory-assembled panels can be made to order to meet the specific requirements of
jobs.

LOGIC & CONFIGURATION
A commonly used logic diagram for a dual circuit (single gas zone) gaseous fire
extinguishing system is shown in Fig 6.2.1. This can be used with an F3200, ME0438-
ME0442 gas control door, one or more Local Control Stations (FP0570), and multiple AVI
Mk2. The configuration and programming of F3200 is as follows.
