3.5 Siren Installation -
Instructions
Noting the best practice guidelines outlined in section 3.4, identify the location of each of the
two Sirens and their corresponding Control Station (as defined by the site survey). Prepare
the Siren cable access and routing paths to the Control Station. Unpack two Sirens “
A
”
(Figure 5) “J-Bar” assemblies “
B
” and Siren cables “
C
” from the transit packaging. Slacken
the Siren U-bolt clamp nuts “
D
” and separate each Siren from its J-Bar.
Securely mount each J-Bar in the desired Siren location using 4 x M10 corrosion resistant
fasteners each rated to a minimum of 25 Kg load capacity (not supplied). Mount each Siren
on its J-Bar, noting that the Siren must be mounted in an upright position, i.e. with the
bracket “
E
” at the bottom of the Siren as illustrated in figure 5. (
This orientation allows water
to drain from the Siren’s drain hole
). Before tightening the Siren U-bolt clamps “
D
”, adjust the
orientation of the Sirens to achieve optimal audio performance for each site.
Connect one terminal of the supplied Siren cables “
C
” (one black / one black with a white
stripe) to the screw terminal “
F
” on the black Siren driver and the other terminal to screw
terminal “
G
” (Refer to figure 5 - It is not critical which wire is connected to each terminal).
Ensure that the screw terminals are securely tightened and that a spring washer is fitted to
ensure the terminal nut cannot loosen under prolonged vibration.
Route both Siren cables to the Control Station enclosure (do not connect cables to the
Control Station at this stage). Ensure the Siren cables are strain relieved via a cable-tie (not
supplied) secured to the J-Bar and that the cables are concealed and tamper proofed as far
as is practicable (use protective conduit if necessary).
