Product Description

Explosion proof drive interface
This signal input interface mainly to be used in middle size fire fighting project. 

Feature:
★No need to set addressable code.
★ Need DC 24V, polarized.
★2-bus, non-polarity.
★ Each explosion proof interface LD4800E-A can connect 1-10 coding explosion-proof smoke detector or heat detector, or 1-10 coding explosion proof manual fire alarm push button.
★ The driving capability is very big. Matched with the E/EN series fire alarm controller, the longest distance between te coding explosion proof detector and the LD4800E-A explosion proof drive interface can be up to 1500 meters. If there is larger load, it is proposed the distance within 1000 meters.
