2.2.2 Input/output capability
The Vortex system is a control panel for gas and fire detectors. It can be used with the
following detectors:
2 wire sink, or 3 wire sink or source 4-20mA detectors. Crowcon manufactures a wide
range of flammable and toxic gas detectors and oxygen detectors. See Appendix D for the
Crowcon range. The detectors of many other manufacturers can also be used, including 4-
20mA fire detectors, however the behaviour of these detectors should not be confused with
that of the conventional loop powered fire detectors referred to throughout this manual as Fire
Detectors.
Conventional loop-powered fire detectors and manual call points (up to twenty devices)
with a maximum loop current of 60mA. Only 1 fire loop may be connected to each Quad
Channel Input Module. Vortex has been tested for use with the Apollo range of conventional
smoke/heat detectors. Other manufacturers’ detectors or other devices such as flame detectors
may also be used. Contact Crowcon for further details.
