Product information


• Safety internal barrier, powered by zones and with Zener diodes for use in conventional fire detection systems to protect hazardous areas.

• Each zone contains two stages of pulse-tested Zener diodes or forward connections and an 'easy' termination resistor. At In the event of a power failure in a safe area, voltage limiting diodes can reach the hazardous area and current limiting resistors. Fuses protect the diodes and two voltage limiter stages ensure continued safety in the event of any stage failure. No circuit may use active output current limiter

• Note: Note that the unit ground connections are made via a DIN rail connection (this product MUST be grounded).
