Product Description:The PRECISION Mini Switch Monitor and Priority Mini Switch Monitor Modules supervises the state of one or more single-pole, normally open, dry contacts.  The dry contacts are connected across the module Initiating Device Circuit (IDC) which reports contact status to the PROACTIV system via the PRECISION signaling line circuit.  The module’s address and the input circuit wiring style of the device being monitored is configurable.  The wiring style can be either Class A (Style D) or Class B (Style B).  The PRECISION Mini Switch Monitor and Priority Mini Switch Monitor Modules are designed to fit into a single gang electrical mounting box and are intended for indoor use only.  They are supplied with flying leads for easy termination.  Function: The modules provide three input states to the control equipment: ‘Normal’, ‘Fault’ and ‘Active’.  The Priority module supports priority event reporting for faster response by the PROACTIV system to the programmed event.  Operation The modules are designed to accept a maximum input circuit line resistance of 50 ?.  An end-of-line resistor required for the monitored switch circuit is 47 k?. Features: Single programmable supervised input Supervised input monitoring Class A (Style D) Class B (Style B)  Three input states Normal Active Fault PRECISION SLC device Style 4, 6 or 7 wiring  Addressable High speed response via Priority Event reporting Specifications: Device Type PRECISION Addressable Device PRECISION SLC NFPA 72 Style 4, 6 and 7. Style 7 requires the use of isolators Operating voltage 24 VDC Input Circuit 47 k? end-of-line resistor 50 ? maximum wiring resistance NFPA Class A (Style D) or Class B (style B) circuit wiring  Maximum current consumption at 24 V Quiescent 47 k?
