alarm condition displayed (see figure 1 for operating
interface image). Alarm panels are interconnected
4
by data transmission cable. Relay interface units are
available to input conditions into existing alarm systems
or building management systems.
The alarm panel also constantly monitors the integrity of
the internal circuits, interconnected wiring and system
monitoring source equipment. In the event of any defect
within the monitored functions, the SYSTEM ALARM
LED illuminates (flashing) accompanied by the audible
warning, and the defective gas service alarm display
status bar illuminates.
An internal maintenance push-button is provided
for use when the plant or pipeline is shut-down for
prolonged periods (see See figure 2). This facility
enables 'permanent' muting of the audible warning for
a particular gas service and is automatically reset when
pipeline pressure returns to NORMAL or a new fault
status occurs.
See figure 2 for identification of main components.
Figure 3 shows the electrical connections.

Standards

Central alarm panels are fully tested prior to dispatch and
packed to provide maximum protection during transit.
The alarm panels are designed to operate in an ambient
temperature of between 0°C and +40°C. Component
assemblies must be stored in their packaging in dry
conditions and storage temperatures must be between
-10°C and +50°C. Alarm panel enclosures can only be
accessed with the use of a tool, mains terminals have
recessed screws to prevent finger contact even with the
door open, and electrically bonded to earth is provide to
backbox and door for a safe installation.
