Autronica manual call point with SelfVerify function. EEx ia-version for use in all zones. Up to 2 x M20 cable glands. BF-503/EX is a manual call point/release station for use in hazardous area zone 0, 1 or 2. It must be connected to the approved AutroSafe barrier BZ-500. The BF-503/EX has been designed for use with Autronica’s interactive fire alarm system, AutroSafe, and comprises the SelfVerify function. This function ensures the highest grade of reliability and the lowest degree of manual testing, because all units comprising this function are automatically self-tested once every 24 hours. The high IP degree and mechanical strength of the enclosure makes the call point suitable for outdoor applications in industrial, maritime and offshore installations. The BF-503/EX must be installed according to local regulations, which normally means along escape routes, landings and exits.
