Key Terms
Fire OWS
The Fire OWS is a UL 864 UOJZ Listed fire-specific OWS that can view
the entire MIFN and BAS systems, as well as perform standard BAS
functions. While in Monitor mode, the Fire OWS can only view the
MIFN; in Active mode, the Fire OWS can respond to changes-of-state
from IFC panels and provide control of IFC panels and devices.
The Fire OWS has several features and required operating procedures that
are different from the standard OWS. Key terms related to the Fire OWS
are defined below.
Active Fire OWS
The Active Fire OWS can acknowledge Change-of-State (COS) messages
such as fire alarms, security alerts, troubles, and supervisory conditions
from a particular Fire-Net NCM or group of Fire-Net NCMs and its
associated IFC panels on the MIFN. The Active Fire OWS can also
activate or deactivate IFC panel control devices, enable or disable
operation and reporting of control and reporting devices, and monitor the
MIFN and perform standard BAS functions. Each Fire-Net NCM may
have one and only one Active Fire OWS at any time to meet UL 864
requirements. Only the Active Fire OWS allows the operator to
acknowledge, signal silence, and reset alarms.
Monitor Fire OWS
All Fire OWSs that are not in the Active mode are in Monitor mode,
which allows them to monitor the MIFN, as well as monitor and perform
standard BAS functions. A Monitor Fire OWS has the ability to become
Active. For example, a Fire OWS in Monitor mode can also be Active for
some Fire-Net NCMs on the MIFN or can become Active for any of the
Fire Net NCMs on the MIFN if the fire acknowledge function is
transferred.
Fire Alarm System Report Dialog Box
The Fire Alarm System Report Dialog Box is a special report window that
is used at the Active Fire OWS to alert the operator to alarms, troubles,
supervisory, and security alert (alarm) conditions.
IMPORTANT:
Read the message in the dialog box before acknowledging
the report. Do not leave unacknowledged reports on the screen.
