• Sentrol’s 6197 Intrinsically Safe PIR system consists of two units: PIR and Barrier Box. The PIR is installed in the hazardous area while the Barrier Box is installed in the nonhazardous area. Sentrol’s 6198 Non- Incendive PIR consists of an encapsulated, selfcontained PIR (without barrier box) for use in nonincendive applications.
• Both the 6197 and 6198 utilize a dual pyroelectric sensor with jumper selectable one- or two-zone detection. These also feature a sequence processor that combines bi-directional pulse counting and Motion Verification, the most sophisticated signal processing available. An opaque, high resolution Fresnel lens focuses the infrared energy on the pyroelectric sensor while blocking stray or reflected light. The unit includes three lenses: standard, vertical barrier, and long range. The PIR is housed in a cast metal housing designed to mount flat on a wall. The case, as well as the mounting screws are gasketed for water resistant rating.
• The 6197 utilizes Factory Mutual and UL Listed barriers provided in the Barrier Box that limit voltage and current on the PIR wiring to intrinsically safe levels. The switching module inside the Barrier Box provides protected relay contacts for alarm and tamper loops for connection to the alarm panel. The Barrier Box includes a NEMA-4 rated steel box with a lid.
