External Solar Siren
The Siren and Solar Panel are all encapsulated within
a tough polycarbonate housing. This housing provides
full protection against adverse weather conditions.
An LED/Strobe unit is built into the siren to act as a
visible deterrent/indication that the system is active.
The Strobe LEDs will slowly and alternately flash
whether the system is armed or disarmed. However,
during an alarm condition the Strobe LEDs will flash
rapidly.
An integral anti-tamper switch provides additional
security protection to the Solar Siren and will
immediately generate a full alarm should any
unauthorized attempt be made to interfere with and
remove the Solar Siren cover.
The Solar Siren is powered by a high capacity battery.
A Solar Panel mounted on the top of the housing
charges the battery during daylight hours. During
darkness, only a small amount of energy is required to
operate the Solar Siren unit.
An Alkaline 9V PP3 battery is supplied in the Solar
Siren to boost the initial power to the unit when the
system is first activated until the Solar Panel charges
the main battery.
Positioning the Solar Siren
The Solar Siren should be located in a prominent
position so that it can be easily seen and heard. The
Solar Siren should be mounted on a sound flat surface
so that the rear tamper switch is not activated when
mounted. Ensure that the tamper switch does not fall
into the recess between brick courses as this could
prevent the switch from closing and give a permanent
tamper signal.
Although the Solar Siren is designed to work on any
aspect wall, for optimum performance you should
refrain from mounting the unit on a north facing wall,
where possible.
Shadows cast by neighbouring walls, trees and roof
overhangs should also be avoided. If the Solar Siren is
to be mounted below the eaves, it should be
positioned a distance of at least twice the width of the
eaves overhang below the eaves. Remember that in
winter the sun is lower in the sky and you should avoid
winter shadows where possible.
