GDA 4020 : Two Channel Gas Detection Controller

The GDA 4020 control unit has 2 x 4-20 mA i/p with 3 associated programmable relay alarm levels per sensor. There is an independent fault relay. There are 3 x analog o/p’s which can be configured for either channel as 4-20 mA, 0-20 mA, 0-5 V or 0-10 V. The controller has an isolated RS485 o/p which can be configured to drive modbus or an interface to the M2001 mimic panel. All configurations are carried out via the front panel push buttons. The unit requires 24 VDC.

GDA 4080 : 8 Channel Gas Detection Controller

The GDA 4080 Gas Detection Controller is designed to be to take up to 8 x 4-20 mA sensor inputs and display the gas readings of individual sensors. The multi-colour display will indicate the alarm status alarm levels and faults. There are 8 fully user configurable relays; and an additional fault relay. The GDA 4080 has a MODBUS interface allowing all the sensors to read into BMS systems. The system has an independent two wire comms system to drive remote mimic panels which indicate the current gas levels in their associated area. It is housed in a enclosure with a swing door making cable access and servicing easy

M2001 : Flush Mount Mimic Panel

The M2001 is a low profile flush wall mounted MIMIC panel. These units are used on multi entry rooms so that users may view the gas levels and alarm status of each entry point for entering the room The M2001 is used in conjunction with the GDA 4020 AND GDA 2400 control unit. The M2001 derives its power and RS485 communications from the 4020/ 2400. The unit’s backlit LED display shows the real time concentration of the gas sensors connected to the 4020/ 2400 and any alarms that occur. The M2001 has an inbuilt sounder which can be muted from the front panel. The unit has two alarm relays which activate and deactivate in conjunction with the alarm status of the 4020 and 2400 control panel.

MS001 : Flush Mount Mute Switch

The MS001 uses one of the alarm SPCO relays from the GDA 4020, GDA 4011, or GDA 2400 to drive the AVR-20R/YM sounder- flasher. The sounder- flasher can be muted by incorporating the MS001 into the o/p switched 24 VDC from the control panel. The sounder will sound when a gas alarm occurs and continue sounding until either the alarm level falls below its threshold value or the MS001 button is pressed. The Mute function automatically resets when the alarm condition terminates.
