Chapter 7 Programming; Response Times - Trane Engineered Smoke Control System Application Manual

Chapter 7
Programming
Programming occurs after hardware installation is complete. The smoke
control system must be programmed for automatic response, weekly self-
testing, end-process verification, and response to manual FSCS
commands.

Response times

Time response requirements must be kept in mind when programming.
They are give in Table 27.
Table 27. Time response requirements
Response time
10 seconds
15 seconds
60 seconds
75 seconds
200 seconds
The 10 second time limit mentioned in Table 27 controls how fast Tracer
Graphical Programming (TGP) programs can be run. Suggested program
rates are 2 seconds for communication watchdogs and 4–5 seconds for
control programs.
Process
(UL 864: 49.2.a)
The maximum time allowed from when an acti-
vation signal is received until a fire or smoke
safety function is initiated. An activation signal
could be from the FACP of the FSCS.
The maximum time allowed between a feed-
back signal activation and an FSCS panel indi-
cation (either audio or LED). A feedback signal
will typically be a binary value, either hard-
wired or communicated.
(UL 864: 49.2.c)
Fan operation proof of desired state, either on
or off.
(UL 864: 49.2.c)
Damper position proof of desired position,
either open or closed.
(UL 864: 49.2.b)
The maximum time allowed between determi-
nation of a failure state of critical equipment or
process and notification of that failure. A failure
state could include communication failures or
equipment problems such as a fan not starting
as commanded.
