Connecting two fire dampers
You can connect two fire dampers. When connecting two fire dampers, the contact functions must be connected in series as outlined
below. Note that the two extra wires from dampers (S3 and S5) are not used. Connect the supply voltage from Neutral and relay 5 in a
parallel circuit.
Mount junctions in an external junction box (not supplied by Nilan)
Connect up S1-S6 to Nilan’s fire automation box as shown under “Connecting fire dampers”
Fire damper 1 Fire damper 2
Connection Box for user selection and EM-box/DTBU simultaneous with fire automation
system
If the Fire automation system has been activated in the software, and you want to run cooker hood extraction in combination with an
EM-box/DTBU damper, Nilan can supply a Connection Box for connecting up the EM-box/DTBU damper.
You can connect up the Connection Box to the Nilan Fire Connection Box (as illustrated). The fire damper is also connected up here.
