The Shield A-XT 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 Shield A-XT Releasing Fire
Control Panel. Status unit functions are non-configurable on the fire control
panel.

Internal Power Supply
The internal power supply of the Shield A-XT Releasing Fire Control Panel meets UL 864, 9th edition and
provides a 2 Amp, linear power-source for operating FACP functions as well as charging the standby batteries.
The 2 Amp power supply operates 115 VAC and 230 VAC models of the Shield A-XT Releasing
Fire Control Panel.
Reference Appendix C, Calculations to determine load current limitations of the 2 Amp power supply
Features of the internal power supply include:
Power Outputs
The Shield A-XT Releasing Fire Control Panel provides power outputs the terminals of NAC 1, NAC 2, and
NAC 3, AUX 24V, STATUS UNITS and EXTING. terminals.
Reference Section 3, Installation and Appendix A, Specifications for further information concerning NAC, Releasing,
Status Unit and AUX 24V outputs of the Shield A-XT Releasing Fire Control Panel.
Releasing Circuit
The Shield A-XT Releasing Fire Control Panel provides features for operating releasing signal delay, device
supervision, releasing emergency abort, flood control and manual release.The Shield A-XT Releasing Fire
Control Panel operates releasing devices in compliance with Fire Protection Service Valves under UL 260, UL 429 and
UL 429A.
NAC Outputs
NAC outputs of the Shield A-XT Releasing Fire Control Panel are programmable and can be operated in
regulated or special application mode.
Reference Appendix A, Specifications for constraints and operating levels of these NAC output modes.
Battery-backup Provides battery power to the load when the AC input of the power supply falls
below the rated level. The voltage at the load remains within the specified range
during these switching-transitions.
Battery-boost Boosts voltage when the battery voltage drops due to a low-battery condition.
Short-circuit protection Provides a shut down on the load side of the power supply when the load-current
exceeds the maximum level.
Automatic-retry Restores output to the load when operating conditions return to nominal levels.
This feature restores voltage levels at the load following conditions such as
over-current and battery depletion.
Status The AC input to the power supply is supervised by the A-XT Releasing Fire
Control Panel with Releasing. The control panel provides an LED status display
for normal and trouble conditions. Normal conditions occur when the power
supply is operating in an acceptable range. Trouble conditions occur when the
power supply is not operating in an acceptable range.
