3.4 Siren Installation - Guidelines
Two Sirens may be connected to each Control Station. The location and mounting position
of each Siren should be determined in advance during the site survey so as to optimise
audio coverage and clarity. Sirens are mounted using the supplied "J-Bars" (1 Siren per J-
Bar)
Avoid orienting the Sirens so that they directly face other Sirens or so that they are inclined
towards acoustically reflective surfaces (walls, awnings, canopies etc)
Ensure that Siren cables are neatly routed, properly strain relieved and tamper proofed as
far as is practicable (use protective conduit if necessary).
Do not locate or orientate the Sirens directly at "ear level" or so that they are within 5m of
personnel workstations.
