Areas such as munitions depots, grain storage areas, and chemical plants can often<br />
involve explosive atmospheres. It is imperative, therefore, that PIRs used in such<br />
areas contribute no electrical signal or field that could cause ignition.<br />
Mount the 6197 Intrinsically Safe PIR in the hazardous area using either a sealed<br />
cable or sealed conduit fitting. Replace the standard lens with either of the other<br />
two lenses if needed.<br />
Mount the Barrier Box in the non-hazardous area next to the alarm panel.<br />
Run wire between the Barrier Box and the alarm panel terminals. Connect the<br />
ground lug on the bus bar inside the Barrier Box to an intrinsically safe ground<br />
using a 12 AWG wire or larger. Connect the chassis ground on the alarm panel to<br />
earth ground.<br />
Remove the front housing and install the jumpers in the PIR in the walk test<br />
mode. Select either one or two zone mode. Replace the front housing with the<br />
rubber gasket using four screws. Walk test the PIR. Install the Barrier Box lid.<br />
The Sentrol 6197 Intrinsically Safe PIR System is FM-approved and UL Listed<br />
for use in hazardous locations. For non-explosive applications that still require<br />
class I, Division 2, Groups A, B, C & D use the 6198 Non-incendive PIR.<br />
