Suppression
Release
Introduction This section describes how to configure Suppression Release Hazard Areas using the
programmer.
Suppression Release refers to the release of water or chemical agents in response to alarm
conditions. Suppression Release operation is limited to hazard areas, which are collections of
initiating devices, signaling appliances, and releasing peripherals, powered by NACs, that are
set up to respond to alarm conditions.
Suppression
Release General
Capabilities The 4007ES panel is capable of controlling either a preaction/deluge sprinkler system or an
agent release extinguishing system.
• The number of hazard areas that the 4007ES panel is capable of monitoring is restricted by
the hardware and point capacity of the panel. Each hazard is defined as a separate area
containing its own 4090-9005 or -9006 releasing peripheral and solenoid.
• Table 9-1 lists the number of Notification Appliance Circuits required by each hazard area of
the 4007ES FACP.
• The releasing peripheral activates its output, which attaches to the solenoid, only when the
designated initiating devices and the NAC connected to the release peripheral are active at
the same time. This prevents a malfunctioning input from triggering a release.
• Releasing signaling patterns are as follows:
• Dual Detector Application. Temporal on first alarm (can also be configured as 20 beats
per minute). Signal changes to 120 BPM on second alarm. When the releasing
appliances activate, the tone changes to Steady.
• Single Detector Application. When an initiating device in the hazard area activates, the
system does one of two things: If a delay timer is used, the NACs play a 120 BPM
signal as the timer counts down. This changes to a Steady pattern when release occurs.
If no delay timer is used, the releasing appliances activate as soon as a single detector
enters an alarm state. In this case, the NACs sound a Steady tone pattern and no
distinct pre-discharge tone pattern plays.
• Alarm Triggered by Activation of Manual Release Station. If a delay timer is used, the
system plays a 120 BPM signal on the NACs as the timer counts down. When the
delay timer reaches zero, the releasing outputs activate and the signal changes to a
steady tone.
Table 9-1. Number of NACs for Hazard Area
Each hazard area requires three to five conventional or virtual NACs, depending on the use case and options selected. One
conventional NAC is required to power the Suppression Release Peripheral (SRP). The other outputs can either use conventional
NACs or Virtual Notification Appliance Circuits (VNACs). The information below describes the operation associated with the available
suppression release NAC/VNAC point types.
• The RELSIG circuit for audible notification typically consists of a horn and provides escalating cadence patterns to identify the
stage of events (i.e., first alarm, confirmed alarm, release).
• The RELWVIS circuit for visual notification is used to alert when the first stage of a cross-zoned releasing sequence occurs or when
a delayed action is used.
• The RELVIS circuit for visual notification is activated when the releasing output activates and remains on until System Reset. It can
be used in systems without cross-zoning and without a delay timer to indicate the release output activation. It can also be used in
systems with cross-zoning or a delay timer to provide a separate indication that the release output activation has occurred outside
entrances of the hazard area.
• The SUPRELS circuit controls the power to the SRP. This circuit must be a conventional NAC, not an addressable VNAC.
• The RELISIG circuit controls audible and visual notification appliances when the system is configured to have a NYC Abort
Investigation timer. Although an audible signal type, this NAC can connect sounders and strobes to the same circuit as required by
NYC requirements. The audible portion of these appliances activates on steady when the NYC investigation timer activates and
turn off when the investigation timer reaches zero. The NYC Abort option does not comply with UL 864.
