terminal on the power supply board MD 1011 is dedicated to supply power for devices For wiring information see LT 1083RCU FX 3500RCU Installation Manual Hazard Zones zones are configurable by correlating input devices releasing circuits pre release and manual release and abort switches Abort switches are only configurable in Preaction Agent release applications Delay timer is only configurable for Deluge applications PER NFPA 72 System releasing circuits will not initiate an alarm signal due movement of waste water surges or variable pressure Counting Zone Type applications must be configured with one of the following Counting Zone types of any one input device correlated to the hazard zone will initiate release process of any two input devices correlated to the hazard zone will confirm alarm and initiate the release process of any three input devices correlated to the hazard zone will the release process Input Types of any two different input device types ion photo heat etc to the hazard zone will initiate the release process Abort Type applications must be configured with one of the following Delay Timer types the Abort switch is pressed the release timer will reset and then restart If the switch held for any time up to 50 seconds then the releasing device will actuate 60 seconds the switch is pressed However if the switch is held for longer than 50 seconds then releasing device will actuate 10 seconds after the switch is released as ULI with the following condition For the Abort switch to function you must press hold the Abort switch before the second zone goes into alarm the Abort switch causes the control panel to add 90 seconds to the Release Timer RDT and holding the Abort switch stops the Release Delay Timer RDT from down Releasing the Abort switch resumes the count down of the RDT the Panel timer does not start while you press and hold the Abort switch Press the Abort switch the timer resumes counting down Press the Abort switch again to restore the timer to full value Release the Abort switch and the timer resumes counting down Configurable Timers applications may be configured with the following timers amount of time from when the Hazard Zone is activated correlated input devices until release maximum value for the RDT is 60 seconds amount of time that the releasing circuit will be active the expiration of Soak Timer the releasing circuits will shut off Only configurable in Deluge applications maximum value for the SDT is 600 seconds the SDT to 0 seconds causes the releasing to shut off ONLY when the system is reset amount of time from when the Manual Release Switch is until release maximum value for the MRDT is 60 seconds Delay Timer Delay Timer Release Delay Timer Manual Release cannot be aborted once it has been initiated Use ULC listed Manual Release such as MS 704 U and MS 714 U Hazard Zone States escalating Hazard Zone states are as follows Hazard Idle Hazard Alarm Hazard Release states are defined based on the status of Hazard Area input devices and correlated Abort Manual Release Switches Hazard Idle Hazard Zone is Idle when Release Delay Timer RDT is not started are insufficient alarm conditions to activate the Hazard Zone For more see Chapter 1.2 Counting Zone Type Manual Release Switch is not active this state corresponding NAC circuit s is off Releasing circuit s is off the Panel Hazard Alarm pre discharge panel enters the Hazard Alarm state when detects the Hazard area confirming alarm input device For more information on alarms see Chapter 1.2 Counting Zone Type a Single Counting Zone hazard area a single alarm input device will put the Hazard into the Hazard Alarm state Manual Release switch is activated releasing process continues as follows Release Delay Timer RDT or Manual Release Delay Timer MRDT is started Corresponding NAC s turns on at Alert rate Release Delay Timer RDT or Manual Release Delay Timer MRDT expires Hazard Release panel enters the Hazard Release state when releasing process continues as follows correlated releasing circuit is activated Corresponding NAC s switch to Evac rate General Operation the Hazard Zone is Idle activation of a Manual Release Switch starts the Manual Delay Timer MRDT The expiration of the MRDT activates the releasing the Hazard Zone is active and the configured time for the Manual Release Delay MRDT is less than the time remaining on the Release Delay Timer RDT once MRDT expires the MRDT activates and release occurs If the RDT is less than the once the RDT expires the RDT activates and release occurs the Hazard Zone is activated by the Manual Release Switch it cannot be aborted the Hazard Zone is activated by any other method any configured abort switches will as described in 1.3 Abort Type Reset will reset all circuits including releasing circuits When using a system that requires the activation of two automatic devices detector installation spacing must be reduced to 0.7 the linear spacing in accordance with National Fire Alarm Code 72 meet the requirements of NFPA 12A Clean Agent Fire Extinguishing and NFPA 2001 Water Mist Fire Protection Systems the Authority Jurisdiction may require to have the Manual Release Switch override Abort Switch To accomplish this the FX 3500RCU configuration set the Man Rel Priority flag for the Hazard Zone to Yes Releasing Circuit Wiring
