Field Devices Vortex Manual

FIELD DEVICES
If a fire is detected (either the fire detector switch closes or the call point is activated), the current
flowing in the loop changes and the Quad Channel Input Module detects this and a fire alarm is raised.
Figure 18 in Appendix B shows the electrical connections to be made to the Quad Channel Input
Module. For essential information about earthing, see Appendix F.
5.3.1 Fire detector location
It is beyond the scope of this manual to describe the rules and regulations governing the installation of
fire detection equipment. Assistance and guidance should be sort from the governing body in the
country concerned before fire detection equipment is installed.
Further advice is available from Crowcon if required.
5.4 Connections for audible/visual alarms
Vortex is able to drive audible and visual alarms via any relay outputs. Any 20 – 29.5V dc field device
(to a maximum of 500mA) may be powered by the dedicated dc outputs on the Power Monitoring
Module.
For essential information about earthing, see Appendix F. For further assistance, please contact
Crowcon.
