1. B312RL B312NL e Suitable for automatic detectors in conventional technology e Relay output with dry change over contact e Connection to control panels with 12V operating voltage e Test contact for examining the Detector Relay Base Series detector line without detectors e Mechanical theft protection can be activated The Detector Relay Base B312RL B312NL with integra ted relay output is designed for the easy connection of automatic detectors Series 300 Due to its robust multi wire screw terminals the detectors can be wired with ease thus achieving a secure and durable connection The relay output is activated through the alarm acti vation of the inserted detector In the Detector Relay Base B312RL the relay output remains active until the operating voltage is briefly interrupted In the Detector Relay Base B312NL the detector and the relay output are automatically reset a few seconds after detection of the fire alarm During construction work or when the detector has been removed the detector line can be connected through via an auxiliary contact which Is integrated into the base With that the whole wiring of the detector line can be examined without risking contamination of the detectors The contact is automatically opened by installing the detector The detector base is designed for surface mounting in dry rooms A mechanical theft protection of the detec tor can optionally be activated at the d2. etector base Operating voltage 8 5 15VDC Current consumption typ 20pA quiescent 50mA active Contact rating 1A at 30VDC Ambient temperature 20 C to 70 C Relative humidity 5 93 no condensation Dimensions x H 127 x 29 mm Colour cream Weight 96g Order number 246101 Order name Detector Relay Base B312NL Order number Order name Detector Relay Base Conv 300 SS B312RL 246102 Detector Relay Base Conv 300 SS B312NL Building Safety Building Security LABOR STRAUSS SICHERUNGSANLAGENBAU GMBH e A 1231 WIEN WIEGELESTRASSE 36 TEL 43 1 52114 0 FAX 43 1 52114 27 OFFICE LST AT WWW LST AT ALL RIGHTS RESERVED B312xL_DBL_LST_EN_0804 PDF PAGE 1
