The FHSD700C detector can also be reset remotely by applying 24 VDC to the remote reset input on
the Main I/O PCB (please refer to Section 3.2.1).
Note: When the Operator Access Code is entered (default = 0), the Sounder Silence, Reset and Isolate
user functions are enabled and the unit is placed in the Unlock state, as shown by the flashing
Unlock indicator. To reduce the possibility of leaving the unit in this condition, the system will
indicate a fault condition on the display and to the remote monitoring device via the fault relay. If
the unit is isolated, then returned to the Normal, Locked state (by pressing the Main Menu
button) the Operator will need to re-enter Operator Code in order to cancel the Isolated state. If
any button is not pressed to lock the panel the unit will self-timeout and lock in 5 minutes.
Note: If the unit is set for battery backup and the mains supply fails (or is removed) the displays will
switch off in order to conserve battery power.

Description
Acts only on the internal sounder. Acknowledges all current Alarm states. All other
warning mechanisms continue unchanged. Sounder operation changes from
continuous to 1 second ON: 15 seconds OFF. New Alarm events cause the sounder to
revert to continuous operation.
Acts only on the internal sounder. The Sounder is switched off until one or more new
Alarm events.
Clears all latched Alarms and Faults. Current Alarms or Faults will remain.
Used when diagnosing faults, testing new installations etc. All alarm relays are
disabled, so that Alarm conditions will not be reported back to the Host Panel. The
Isolate button toggles the unit between Isolated and Normal operation, as shown by the
Isolated indicator, but see note below.
Note: If the unit is isolated then returned to the Normal, Locked state (by pressing the
MENU button) the Operator will need to re-enter Operator Access Code in order to
cancel the isolated state.
Note: If a power cycle is applied to the detector, the detector will not remain in an
isolated state.
