Any attempt to open the siren or tear it off from the mounting surface will set off a tamper alarm. The electronics board is protected by impregnation against unfavorable effects of weather conditions. As the SP-500 housing is made of the highly impact resistant PC LEXAN polycarbonate, hence it features a high mechanical strength and guarantees aesthetic appearance of the siren even after many years of operation.

(see Fig. 2). 2. Installation The SP-500 siren is to be installed on a flat surface, in a possibly inaccessible place, so as to minimize the risk of tampering. The siren should be screwed to its base by means of screws and expansion bolts (the screws and expansion bolts are delivered with the siren).

OUT8 SP-500 Fig. 4. Method of connecting the SP-500 siren to low-current outputs of INTEGRA 32 control panel. Output OUT2 has been programmed as supply one. Output OUT3 controls the relay P1 which triggers acoustic signaling, and output OUT4 controls the relay P2 which triggers optical signaling (low-current outputs with normal polarization are activated by shorting the terminal directly to ground 0 V).
TMP TMP SP-500 Fig. 5. Method of connecting the SP-500 siren to high-current outputs of INTEGRA 32 control panel. Output OUT1 triggers optical signaling and output OUT2 – acoustic signaling (the high-current outputs with normal polarization – activation means that +12 V voltage is supplied).
