Multi-Party Handset Station
General Information
This data sheet applies to the Model 7805-001 Indoor Explosion-proof Multi-Party Handset Station. This
Page/Party® handset station provides safe and clear five-party line communications in hazardous areas, even
in high-noise situations. It is NRTL-certified for use in the US and Canada for the following areas: Class I,
Div. 1, Groups C and D; Class II, Div. 1, Groups E, F, and G; and Class III, Div. 1.
The Model 7805-001 includes a front-panel push button for paging, a 6-foot PVC coil cord, a noisecanceling microphone for reduced transmission of background noise, and sidetone circuitry. An electrical
safety barrier mounted inside the housing creates an intrinsically-safe handset. It also includes a durable
rotary switch for party line selection.
