Sounder bases

System Sensor's B200SR intelligent sounder bases can be used as part of a general evacuation signal.


System Sensor launched the B200SR intelligent sounder bases, which support the System Sensor synchronization protocol, enabling them to be used as part of the general evacuation signal. They meet UL 268 and UL 464 requirements. Installers attach the mounting plate to a standard junction box, which is left free to store excess wire. The base then connects to the mounting plate for a surface-mount look without exposed components. The base’s mounting screws are then covered by the attached sensor head to prevent tampering.
