Installation and Commissioning
This equipment is to be installed, serviced and maintained by a suitably qualified technical person with the
requisite knowledge of electrical and fire safety installations.
Location and Mounting
It is best to locate the Noby-220iiiiR2 in a public space, e.g. a hallway or landing area, where the LED
Strobe/Lamp is visible and the internal alarm sounder can be clearly heard. Another consideration is to
position the panel to make most effective use of the LED Strobe/Lamp, which switches on automatically in
the event of mains power loss.
The Noby-220iiiiR2 is intended for indoor use only, and must be sited in a dry environment. Do not site the
Noby-220iiiiR2 outside, or in any location where it may become exposed to damp or freezing conditions.
All components are selected to operate within their specification when the environmental conditions outside
the enclosure comply with class 3k5 of EN60721-3-3:1995; temperature range -5°C to +40°C; 95%RH. The
enclosure is rated at IP30, which offers protection against tools and wires greater than 2.5mm width, but no
protection against liquids.
Mount the Noby-220iiiiR2 securely onto a flat solid surface at the three fixing points denoted by ‘MH’ in
Figure-2, using wall fixings appropriate for the material. In some situations it may be desirable to recess the
panel into a hollow section wall, in which case the ‘Noby-220iiiiR2 Flush Mounting Kit’ provides the necessary
fixing harness and stainless steel frame.
Connecting the 230VAC supply
Connect the 230VAC to the Noby-220iiiiR2, paying strict attention to local wiring regulations. A readily
accessible disconnect device shall be incorporated into the building installation wiring. Feed the cable
securely through the rear cable-entry hole CE2, or via a 20mm cable-gland CG4.
Alternatively a 3-core 230VAC flexible cord can be fed through CG5 (top) or CG6 (bottom) using the strain
relief bush supplied (suitable for cable diameters 6.2mm to 7.4mm). In this case ensure that the cord is
connected to the building installation wiring via a readily accessible disconnect device fitted with a 2A fuse.
Strip back the outer sheath of the cable 25mm and then strip back each inner core 6mm, such that
the cable double insulation is preserved inside the enclosure to within 25mm of the screw
terminals.
The Noby-220iiiiR2 is Class-1 equipment and shall be earthed. Connect the earth core of the
incoming cable to the earth point on the enclosure. Consult a qualified electrician if there are
doubts concerning electrical safety.
