housing DJZ1193 for FDAI93-Ex
When using alarm indicator FDAI93-Ex in wet areas,
surface-mounted housing DCA1191 (accessory) or
indicator housing DJZ1193 (accessory) must also be
fitted.
Max. four alarm indicators FDAI93-Ex can be fitted in the
surface-mounted housing DCA1191. The necessary
installation holes of ø 22.5 mm must be made by the
customer. The washers must be ordered separately.
