Gasmonitor Plus is Crowcon’s flexible 19″ rack-based control system for gas detection monitors. Monitor up to 16 gas detection monitors or 32 fire zones per rack. Racks can be supplied separately or built into wall mounting or floor-standing enclosures.
A separate gas level display is provided for each gas monitor. The Gasmonitor Plus can be engineered into large systems and tailored to suit individual site requirements.
Simple to use
- All day-to-day functions are available from the front panel – push buttons for simple operation
- Unique bar-graph display per channel – provides an instant representation of gas concentrations
- Common alarm LEDs on the display card – the whole rack status can be checked at a glance
Flexible architecture
- The system is limitlessly expandable
- Modular construction – ultimate customisation and minimal wiring
- Industry-standard analogue outputs – will integrate fully with existing rack-mounted protection systems on-site
- Optional relay modules – flexible and cuts down on configuration and monitoring cabling
Easy maintenance
- Each channel is inhibited separately – plant safety is not compromised during checks
- Routine calibration from the front panel – reduces service overheads by half
- One universal gas card – reduces spares holding
Each Gasmonitor Plus rack consists of a display module, a card frame that will accept up to sixteen input modules, an input/output module, a data logger and software. Input modules, relay modules and module membrane labels must be ordered separately.
The operating voltage of the rack is 24Vdc. 100/230Vac power supplies and backup batteries must be ordered separately.
Backup batteries are available as an option to ensure the system remains operational if mains power fails. Dedicated 24 V alarm outputs power a maximum of two audible/visual alarms per rack. Additional alarm devices can be activated using relay modules.

| Gasmonitor Plus is a 24Vdc system and requires two of the above batteries in series. | |
| Battery charger assembly | |
| A Gasmonitor Plus rack system can charge batteries up to 17Ah capacity. For larger batteries or for multi-rack systems, a separate charger assembly is required. The assembly is supplied on an aluminium plate, which fits into the wall-mounted enclosures’ swing door. The module comprises a mains surge suppressor, battery charger, deep-discharge module (to protect the batteries) and terminals for connecting up to four racks. The operating voltage for the charger must be specified (110 or 230Vac). A suitable power supply (for powering the Gasmonitor system) and batteries must be selected separately. Contact Crowcon for 2 rack 2x17Ah systems. | |
