Device States
States are normally used to switch sensor sensitivity or to disable the sensing channel during specific times of a day. For example
the optical smoke sensing channel may be disabled during normal working time in an area where smoking is allowed and occupants
can smoke in the designated area and the channel is enabled to a sensitive state during non working time.
Non defined states
"
If a non defined state is selected during commissioning then the control panel will revert to State 15. Which
means the device is functionally switched OFF .
Optical heat (sounder) sensor states (34000 range)
These states cover the following sensors:
¨
Optical heat sensor
¨
Optical heat sounder
¨
Heat sounder
"
For the Heat sounder product ignore the Optical states.
State
Definition
Application
State 0
(LPC
approved)
Medium sensitivity
Heat Grade 2
Optical smoke normal sensitivity
Suitable for most applications. Provides smoke
detection to meet BS5445:Part 7 and provides heat
detection to meet Grade 2 as defined in
BS5445:Part 5.
State 1
High sensitivity optical or Grade 2
heat
Used in areas or situations where airborne smoke or
dust is unlikely to occur and therefore a more
sensitive detection is available.
State 5
Medium sensitivity optical only
Where high ambient temperatures of greater than
40
o
C are expected in the detection area.
State 8
(LPC
approved)
Medium sensitivity optical with 20
seconds time constant or
Grade 2 heat
This state is useful in hotel bedrooms where low
levels of signal could occur for short durations. If
smoke and heat occur simultaneously the time delay
is effectively overridden to provide fast detection.
State 10
Medium sensitivity optical with time
delay (20 second time constant) or
Grade 2 heat
Similar performance to state 8 without the time delay
overridden. Useful in hotel bedrooms and loading
bays where low levels of signal may occur.
State 11
Low sensitivity optical or Grade 3
heat
Used for smoke detection in areas where airborne
particles or smoke are normally present, or high
temperatures (up to 40
o
C) can be normally attained.
State 12
(LPC
approved)
Grade 1 heat only
No optical smoke detection. Can be used where
airborne particles or smoke could occur briefly or at
specific times. Optical detection can be used in
conjunction with time blocks/slots to enable/disable
sensor depending on application.
State 13
(LPC
approved)
Grade 2 heat only
State 14
Grade 3 heat only
State 15
No detection
This state can be used to provide total disablement
on a timed or temporary basis.
