INSTALLATION
3.4.4 Installing the TAD control unit (optional)
1 Determine the TAD control unit installation location according to project planning.
Dimensions of the TAD control unit, see “Tunnel Adapter Device dimension (all units of
measurement in mm)”, page 99.
2 Drill holes for the TAD control unit as shown in the drilling plan, see “Drilling plan for TAD
control unit for VISIC100SF (all units of measurement in mm)”, page 102.
3 Hammer in the M8 steel tie bar (from mounting kit).
4 Install the TAD control unit.
5 Wiring, see “TAD control unit wiring”, page 35.
3.4.5 Fitting and start-up of the gas sensors (optional)
1 Check the tightness of the packaging of the gas sensors after delivery. Send the gas
sensor back to the manufacturer directly when the packaging is not tight.
2 Check the date of manufacture and/or maximum storage duration.
3 Use the SW 8 Allen key to remove the black screw plug on the underside of the
enclosure.
With a separate power supply, the TAD control unit can be installed at a distance of max.
1200 m to the installation location of the VISIC100SF.
WARNING: Hazard through low voltage
▸ Disconnect the 24 V plug connection in VISIC100SF before start-up or exchanging
the gas sensors.
