INSTALLATION DATA SHEET
R201 and RA201 Series
Carefully twist lens firmly one turn clockwise to remove from base. Remove the inner reflector
assembly from the base of the unit. Fix base to the required surface, utilising rubber gasket, with 2 x M4
screws (not supplied). Insert power cable through aperture in base & connect to terminal block on underside of
reflector assembly.
For DC units connect Positive lead to the terminal block marked ‘+’ & Negative lead to terminal block marked
‘-’. The termination is polarity conscious.
To Re-assemble, position the reflector assembly in the base noting the position of the three internal mounting
lugs. Fix the assembly onto the lugs using the 3 x No.4 screws supplied. Replace lens onto base ensuring that
the base spigot ‘O’ ring is in place. Twist lens one turn anti-clockwise to lock and check that the ‘O’ ring is
positioned correctly and not caught or snagged.
R401/400 Series
Connection to this type of unit is either into the three way barrier strip situated in the base of the unit
(standard connection) or via the M20 side conduit entry. If M20 is the preferred method then the two
wires in the barrier strip in the base need to be unscrewed and freed from the barrier strip. Un-screw
3xNo.4 screws that retain the base plate & carefully remove, threading the wires through the
aperture. Un-screw the same two wires from the internal terminal block. Carefully drill out the M20 entry &
using the appropriate cable gland, insert power cable into unit connecting to the internal terminal block.
Screw base plate back into position. Fix base to the required surface using the supplied gasket with
3 x M6 Hex set screws (not supplied).
Alarm Stages (Modes of Operation)
The RA series is factory wired for combined operation of the audible and visual modes.
For 3 wire control giving independent operation of either lamp or buzzer the following adjustment is required.
Ensure the supply is disconnected before attempting adjustment.
Insert a 3mm flat blade screwdriver into the inspection
slot of the terminal marked ‘+’ (see picture 1) to
release the ‘wire grip’ and remove the Blue lead from
the back of the terminal top row. Be careful not to
dislodge the other Red/White/Blue leads, depending on
the model. Re-insert the Blue lead into the rear of the
unused middle terminal of the block (top row). Check security of all the leads. A third wire ‘+’ can
now be connected to this terminal to allow independent use of lamp and buzzer.
General Installation Notes
• Installation must be carried out in accordance with the latest codes and regulations by a qualified electrician.
• Ensure power is disconnected prior to installation or maintenance.
• Environmental exposure conditions during installation should be dry, not moist or wet.
• The lens of the unit is Polycarbonate Plastic. Do not clean with petroleum based cleaners.
• For all installations, mount the beacon with the lens above the base. Any other mounting position
will impair the IP rating (Ingress Protection) and shorten the working life of the beacon.
• Avoid mounting the beacon where it will be subject to excessive vibration.
