The SCS⁄SCE
Preliminary SCS-8⁄SCE-8 Design Considerations
3.3.1 Inventory
The SCS-8*
The SCS-8 Smoke Control Station provides the capability to control and display the
status of eight AHU fans and dampers. The SCS-8 is capable of two modes of operation, FSCS
for the control of smoke and HVAC for the control of heating, ventilating and air conditioning.
The SCE-8.
The SCE-8 Smoke Control Expander expands the SCS-8 providing
the capability to control and display an additional eight AHU fans and dampers.
Includes an expander ribbon cable for connection to the SCS-8.
The SCS-8L*
The SCS-8L Smoke Control Station provides the capability to con-
trol and display the status of eight AHU fans and dampers via connection to a custom graphic annuncia-
tor. Graphic annunciators are custom made by a multitude of companies. For information on custom
graphic annunciators, refer to Section 3.7 “SCS-8L⁄SCE-8L Installation”. The SCS-8L is capable of two
modes of operation: FSCS for the control of smoke and HVAC for the control of heating, ventilating and
air conditioning.
The SCE-8L.
The SCE-8L Smoke Control Expander expands the SCS-8L providing the capability to
control and display an additional eight AHU fans and dampers via connection to a custom graphic
annunciator. Includes an expander ribbon cable for connection to the SCS-8L.
The LDM-R32.
The LDM-R32 Relay Expander Module provides the SCS-8L⁄SCE-8L with 32 dry
Form-A (normally open) contacts. The relay module serves as a slave to the particular SCS-8L it is connected to. Instead of driving lamps or
LEDs, the ON, OFF, or TROUBLE signals from the SCS-8L⁄SCE-8L module are used to activate the relays on the LDM-R32.
The SCS-8L-CBL24 and SCS-8L-CBL48
.
Cable sets for connecting SCS-8/8L and SCE-8/8L outputs to lamps or LEDs are
provided through the optional SCS-8L-CBL24 (24" long) and SCS-8L-CBL48 (48" long) assemblies. Each cable has a plug
on one end for connection to the annunciator module and stripped and tinned ends on the other end of the assembly. Each
cable supports eight output pins. The SCS-8L-CBL24 and SCS-8L-CBL48 are cable sets that provide several cables, suffi-
cient for most applications.
3.4 Preliminary SCS-8⁄SCE-8 Design Considerations
A smoke control system must not only be able to control a fan or damper, but it must also be able to verify what state the fan or damper is in
(ON/OFF or OPEN/CLOSED). Following is an explanation of how the SCS-8 controls and monitors a fan or damper in conjunction with the
FACP/INA/Network Control Annunciator.
