Placed inside a security or fire four-wire detector.
Bolid S2000-AR-1 mod.01 is a miniature addressable expander designed for embedding inside a four-wire security or fire detector. The device adds addressable capabilities to the detector without the need to replace it: the expander is powered over the two-wire communication line and provides monitoring of the security relay and tamper sensor. This is a cost-effective way to convert existing infrastructure into addressable format within the ISO Orion system.
