Title: bn305_cgb.pdf
The Dual Monitored Input/Output Unit BN-305 has been designed for use with Autronica’s interactive fire detection systems, Autroprime and AutroSafe, and includes the SelfVerify function. This function ensures the highest grade of reliability and reduces the need for manual testing because the panel is able to continuously and automatically check all units that include this function.Note: External devices attached to this interface unit require a separate power source (they cannot be powered by the detector loop). SelfVerify: The unit’s ability to initiate alarm is regularly checked.Function options / Switch settingsThe internal DIP switch S1 selects the function performed by the BN-305 unit. For location of the DIP switch, refer to circuit board drawing on the next page. Refer to detailed descriptions of each function on this datasheet (Descriptions of function options).The available functions include: •Function A Alarm condition signalling input unit with relay feedback
