Wiring diagrams are included in the instructions supplied with all alarms, but here are a few basics.
All mains powered alarms and accessories need a mains supply that is taken from a permanent live feed – for example a lighting circuit.
All of Aico’s mains powered smoke and heat alarms again require a permanent 230V AC mains supply which can be taken from a local lighting circuit or a dedicated circuit at the distribution board. Standard 2-core and earth 6242Y PVC/PVC cabling can be used for the initial mains feed to one of the alarms in the circuit, with the subsequent connections between the alarms having an additional ‘Interconnect’ connection along with the Live, Neutral and Earth connections. 3-core and earth 6243Y PVC/PVC cabling can be used for interconnect cabling.
Once all alarms on the system have been wired, we strongly recommend that you check for the following before connecting the alarms:
Note: Alarms do not need to be earthed, however the terminal marked with the Earth symbol is provided for the convenience of the installer so that any Earth cable can be safely terminated.
