Section 3: The SCS⁄SCE
3.1 Introduction
3.1.1 Hardware Features
The Smoke Control Station (SCS-8) and the optional Smoke Control Expander (SCE-8) are used in conjunction with the following equip-
ment, providing the capability to control and display the status of air handling unit (AHU) fans and dampers.
•
An NFS2-3030 FACP, in FSCS or HVAC mode.
•
An NFS2-3030, NFS2-640 or NFS-320 FACP with a Network Control Annunciator, in FSCS or HVAC mode.
•
An NFS-320 or NFS2-640 FACP, in HVAC mode.
•
Legacy systems: The AM2020/AFP1010 Fire Alarm Control Panel (FACP), in FSCS or HVAC mode.
•
Legacy systems: The AM2020/AFP1010 FACP and an Intelligent Network Annunciator (INA), in HVAC mode, without manual
control.
The Smoke Control Lamp Driver (SCS-8L) and the optional Smoke Control Lamp Driver Expander (SCE-8L) are also used in conjunction
with the above equipment. However, unlike the SCS-8⁄SCE-8, they must be installed in a Custom Graphic Annunciator backbox (see Section
3.7 “SCS-8L⁄SCE-8L Installation”, for more information).
This manual will refer to the SCS-8⁄SCE-8 and the SCS-8L⁄SCE-8L as the SCS⁄SCE when the information pertains to both versions. Other-
wise the information only pertains to the version stated. This table lists abbreviations used in tables and figures in this manual for monitor
and control modules..
One SCS has the capability to control and monitor eight AHU fans or dampers. The SCE is used in conjunction with the SCS, providing the
capability to control and monitor 16 AHU fans and dampers. Only one SCE can be used for each SCS and a maximum of 32 pairs can be
used with each FACP. With the maximum configuration of 32 pairs, the system has the capability to control and display the status of up to
512 separate AHU fans or dampers.
The SCS⁄SCE is capable of two modes of operation; Firefighter's Smoke Control Station (FSCS) or Heating, Ventilation, and Air Condition-
ing (HVAC). In the FSCS mode (not for use with INA, or when smoke control modules are directly connected to an NFS-320 or NFS2-640
EIA-485 circuit), the SCS⁄SCE has the following capabilities:
•
Helps maintain a tenable environment in evacuation routes during the time required to evacuate people from the area.
•
Helps restrict the movement of smoke from the fire area.
•
Helps provide conditions in non-smoke areas that will help fire officials conduct search and rescue operations and to find and combat
the fire.
•
Assists in protecting life and property.
In the HVAC mode, the SCS⁄SCE has the capability of monitoring and controlling the building heating, ventilating and air conditioning. The
HVAC mode is not consistent with the UL and NFPA standards for smoke control. This mode should be used for fan shutdown and building
heating, ventilating, and air conditioning purposes only.
The SCS⁄SCE, when used with an AM2020/AFP1010, or NFS-320/NFS2-640 with an NCA-2, or NFS2-3030 with or without an NCA-2,
complies with NFPA 90A, 92A, and 92B standards for smoke control and UL smoke control requirements (Category UUKL) for Dedicated
and Non-dedicated Systems.
