External Solar Siren
Siren Housing
The Siren, Strobe Light and Solar Panel are all encapsulated
within a tough polycarbonate housing. This housing provides
full protection against adverse weather conditions. All electronic
components are specially treated to ensure long, reliable, trouble
free operation and an integral tamper switch gives maximum
security protection to the unit.
An LED indicator unit is built into the Siren to act as a visible
deterrent and indication that the system is active. The LEDs
will slowly and alternately flash whether the system is Armed
or Disarmed. When an alarm occurs the LEDs will flash rapidly
together.
An integral tamper switch provides additional security protection
to the Siren and will immediately trigger an alarm should any
unauthorised attempt be made to interfere with and remove the
Siren cover, (unless the Siren is in Service Mode).
Rechargeable Battery
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 maintain the Solar Siren unit.
Initial Power-Up Battery
An Alkaline 9V PP3 battery is supplied in the Siren & Strobe unit to provide the initial power to the
system.
Siren Code
An encrypted code is set using a combination of miniature DIP switches. This enables you to select
a unique security code for your installation.
Choosing a Location for the Solar Siren
The Siren & Strobe unit should be fitted to the outside
of the building in a position that is clearly visible and at
a height which is relatively inaccessible to an intruder.
Although the Siren & Strobe is designed to work on any
aspect wall, you should refrain from fixing the unit on a
North facing wall where possible.
Shadows cast by neighbouring walls, trees and roof
overhangs should also be avoided. In practice, the
Siren & Strobe should be positioned a minimum of
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.
