Product Description
The PRECISION Switch Monitor and Priority Switch Monitor Modules supervise the state of one or more single-pole, normally open, dry contacts. The dry contacts are connected across the module input circuit, which reports contact status to the PROACTIV system via the PRECISION signalling line circuit (SLC).
The address and the 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 Switch Monitor and Priority Switch Monitor Modules are designed to mount to 4-inch square or double gang electrical boxes and are intended for indoor use only.
Function
The modules provide three input states to the PROACTIV FACP: ‘Normal’, ‘Fault’ and ‘Active’. The red indicating LED is visible through the cover plate and is lit if the device is in alarm or is being polled.
The Priority module supports priority event reporting for faster response by the PROACTIV system to the programmed event. The PROACTIV system supports multiple event reporting formats to address installation requirements, including “alarm inputs”, “supervisory inputs”, “trouble inputs”, and “manual release inputs”.
Operation
The modules are designed to accept a maximum input circuit wiring resistance of 50 Ω. An end-of-line resistor required for the monitored switch circuit is 47 kΩ.
