the USC423A 868MHz GSM Alarm Panel.
HA71FA
HOUSING
The unit is encapsulated in 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.
SOLAR PANEL
The Solar Panel mounted on the top of the housing will maintain a charge to the rechargeable battery during daylight hours.
During darkness, a negligible amount of energy is released by the rechargeable battery to operate the Siren.
RECHARGEABLE BATTERY
A high capacity 6V 1.2Ah sealed lead acid rechargeable battery ensures that the Siren is self maintained during darkness
and long winter periods.
INITIAL POWER-UP BATTERY
An Alkaline 9V PP3 battery is supplied in the Siren unit to support the initial power up.
LOCATION
The Siren 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.
To provide the optimum amount of sunlight to the Solar Panel, you should ideally mount the Siren on a south facing wall. If
this is not possible an easterly or westerly position will suffice.
Although the Siren is designed to work on any aspect wall, you should try to avoid a north facing wall where possible.
Shadows cast by neighbouring walls, trees and roof overhangs should also be avoided. In practice, the Siren 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.
The Siren contains a sophisticated radio receiver. Reception of radio signals can be affected by the presence of metallic
objects within close proximity of the Siren. It is therefore important to mount the Siren a minimum distance of one metre
away from any external or internal metalwork, i.e. external drainpipes, gutters and internal radiators etc.
INSTALLATION
Remove the screw at the base of the housing and carefully lift off the front cover. All electronic components are housed
within the front cover.
Use the rear back-plate as a template to mark the position of the four fixing holes on the external wall. Drill four holes and
insert the plastic wall plugs. Mount the back-plate using the four screws provided.
