Harrington Signal HAVED-MP - Manual (Page 4)

HMX Control Panel Refer to Master Panel Controls and Display diagram (Page 6).
The Control Panel status indicators are 'Alarm', 'Fault' and 'Power'.
During 'Power On Diagnostics', the system is scanned for active Distributed Panels and
peripherals. The Message Display indicates how many Distributed Panels have been found and
all event buffers are cleared.
The 'Power' indicator is on as long as there is power available to the HMX Master Panel.
The 'Alarm' indicator will be on whenever an Evacuation Signal or Alert Signal is active.
The 'Fault' indicator will be on (blinking) whenever a fault has occurred in the HMX system. The
Message display will indicate a code for the fault that has occurred. In addition, the audible fault
signal will be active (beep tone)as long as the fault persists. The 'Fault Silence' switch can be used
to silence the audible fault indication, but the visual indicator can only be cleared by an HMX
system Reset. If the fault is cleared manually the yellow led indicator can be cleared with a single
click of the reset switch.
The 'All-Call' switch will select all available Evacuation/Paging zones on the Paging/Zone Control
panel when clicked. Individual paging zones may be deselected using the Paging/Zone Control
switches, but a second click of the 'All-Call' switch will deselect the remainder.
The 'System Reset' switch will clear the Master Panel back to it's power on condition but will not
cause the system to rerun the 'Power On Diagnostics' program (see 'Global Reset' below). After
the 'System Reset' has run its course any Evacuation or Alert Signal that has been input will be re-
processed.
The 'System Reset' switch must be clicked twice within a two second interval to take effect.
“GLOBAL RESET”:
A 'Global Reset' can be initiated by holding the "Fault Silence' switch in the up position while the
'System Reset' switch is clicked twice .
This will rerun the 'Power On Diagnostics' program.
Observe the message display during the reset. It will display +0 then the number of Distributed
panels in the communication loop of the HMX system.
