1. Outfit options
Additiona protection e ements (so d separate y) can be insta ed in the siren. They inc ude:
• inner cover of ga vanized sheet, OM-SP500;
• hermetic reed re ay tamper switch, SD/SP-SAB.
Where the reed re ay switch is used, it is necessary to remove the mechanica switch
insta ed by the manufacturer on the tamper e ement, and rep ace it with the new switch. This
operation requires reso dering of the two cab es which connect it with the e ectronics of the
siren (see Fig. 2).
2. Installation
The SP-500 siren is to be insta ed on a f at surface, in a possib y inaccessib e p ace, so as to
minimize the risk of tampering. The siren shou d be screwed to its base by means of screws
and expansion bo ts (the screws and expansion bo ts are de ivered with the siren).
Note: Make sure to leave a distance of about 0.5 cm between the upper edge of the siren
base and the ceiling or another element which limits the mounting position from
above. The lack of such clearance can make the mounting of housing difficult.
After the siren has been insta ed, it is recommended that the fixing screw ho es and the
cab e entry opening be sea ed with si icone compound.
3. Description of siren functioning
The SP-500 siren can work together with any source of a arm signa which, in the a arm
condition, provides 12 V direct vo tage on the signa ing output (outputs). The audib e
signa ing of the SP-500 wi be activated after connecting the 12 V power supp y to the
"+ SA -" termina s, whi e the visua signa ing wi switch on when the 12 V power is supp ied to
the "+ SO -" termina s.
The "TMP" termina s are designed for connecting the siren to the tamper circuit of the a arm
system.
You can choose one of the three types of acoustic signa ing.
