7 of 155
The Quaestor-SZU Releasing Fire Control Panel provides functions for:
Zone Testing The zone testing function provides an automatic reset of zones in alarm.
NAC Delay The NAC delay function suspends the NAC output and permits alarms to be
verified before premises are evacuated.
NAC Reactivation The NAC reactivation function provides an alarm resound.
Voltage Free Relay Contacts Voltage free relay contacts are provided for local control and signalling.
Releasing Delay The releasing delay function suspends the releasing signal for up to 60 seconds.
Releasing Signal The releasing signal provides identification of the pending extinguishant release
and the flow of extinguishant during the releasing process.
Low Pressure The low pressure function provides releasing agent monitoring using a pressure
switch to measure low pressure conditions.
Abort The abort function provides suspension of the releasing count-down when
contacts on an external-momentary-switch are closed.
Deactivation Time The deactivation time function provides a delay setting to control the output
quantity of the releasing agent.
Manual Only Mode The manual only mode disables the releasing operation using automatic
detection devices.
First and Second Stage
Relays
First and second stage relay contacts are provided to trigger equipment outside
the system.
Pre-discharge and Release
Warnings
Pre-discharge and release warnings are provided with separate audible tones
and frequencies. These operating characteristics allow the two warnings to be
differentiated on the fire control panel.
Supervisory Signal Function The supervisory signal function provides audible and visual indications on the fire
control panel and on external status units. This mode also operates the output of
the TROUBLE RELAY. All supervisory conditions are non-latching.
Power Source Failure
Function
The power source failure function provides immediate audible and visual
indications at the fire control panel. The audible and visual indications are also
provided on external status units. Status Units can operate the output of the
TROUBLE RELAY.
Interconnected status units Interconnected status units are provided with a limited set of indicators and
functions compared with those provided on the Quaestor-SZU Releasing
Fire Control Panel. Status unit functions are non-configurable on the fire
control panel.
