AutroGuard Retro 520 Series MultiSensor
– Backward compatible
– Direct drop in replacment for 116-BHH-520 smoke detector
– Gives superior detection, but does not give all the benefits of AutroGuard
– Note: AutroGuard Retro is not recomemended in situations where IP is of high importance. In these cases it is recommened to upgrade the conduit box, base and detector to AutroGuard.
