1.Using methods and steps:
A.Turn the volume switch which contains electrical source switch ,when you hear a sound of jumpiness, the power of siren has been turned on ,then the power indicator shows the siren begins to work .When stop using ,be sure to turn off the volume switch until a sound of jumpiness appears .
B.You only need turn selecting tune switch on the mike when you use microphone.But when anyone of other tunes is working ,you also can press microphone switch to use microphone.The microphone has magnetism ,it can be placed in any right position .
C.When you use emergency light ,you should operate bulb controller.
2.Installation:
A.A bracket turned 180 degree can be used when you install the siren.You should choose proper position to fix it on the vehicle.It can be suspension-installed(remove two bracket nails and change a direction),or installed on the appropriate aeration position such as the flat roof behind windshield directly using the bracket ,never approaching the radiation equipment.
3.Power supply threads connection:
A.The red thread connects to the anode of the 12V electricity bottle;
B.The black one connects to the cathode.
C.Two green threads connect to two ends(no polarity) of the horn(loudhailer).
4.Attention:
A.The 24V electricity bottle can not be used as the power supply(our company has the 24V model);
B.When the siren has electricity-machine interfere sounds,change the connective threads between the automobile engine and the separation-electricity set to high voltage damp threads if the voltage is normal .
C.Check the power switch to ensure the machine is turned off when you leave the automobile .
5.Main parameter:
Frequency and Cycle | Refer to GB8108-1999 | Power Voltage | DC12V±10% |
Output sound pressure | 110-115db(A calculate 2M) | Mainframe volume | 120*132*32 |
Horn impedance | 25W*2 or 80W or 100W | Mainframe weight | 1.8kgs or 2.7kgs or 2.7kgs |
6.Accessory:
A.A electronic source threads; B.A horn
C.Two safety canal(20A) D.Astainless steel hook
E.A operating specification
New improved function:
1.Add a button for selecting siren tones
2.The unit is egodefensed .when the power thread in reversed or the two output leads of the horns short circuit,it will switch off the power by itself.It will keep on working when the aboved problems be solved .
