detection system and its components.
Some of the functionality described in this manual may not be available with some units.

1.2 What is Vortex?
Vortex is a modular gas and fire detection system, designed to monitor remote 4-20mA and
conventional loop powered fire detectors. Other devices may be used as advised by Crowcon.
It can operate flexibly assigned and voted relays if pre-set levels of gas are exceeded or if
smoke or fire is detected. These relay outputs may be used to drive audible and/or visible
alarms. The built-in Modbus communications interface allows multiple Vortex systems to be
connected to industry-standard control monitoring systems.
The Vortex system may be mounted in a variety of enclosure; the options are listed in Table 1
