FIRE2
- the input goes to this state if the following occurs:
the second transition to the
FIRE
state of different inputs of the same zone was occurred in
a time not exceeding 120 seconds provided that the input gone to the FIRE state first does
not change its state.
–
SHORT CIRCUIT
- input circuit resistance is less than 100 Ω;
–
OPEN CIRCUIT
– the input resistance is more than 6 kΩ;
–
ARMING
FAILED
– the input was not normal at the moment of arming
.
Algorithm of One-Threshold Fire Combined Input
Input disablement (transition to the
DISABLED
status) can be done manually only using the
DISABLE command of the network controller (the S2000-M panel ver.4.13 (3.13) or newer).
When enabled, the input goes from Disabled to one of the following states:
–
ARMING DELAY
–
ARMED
–
ARMING FAILED
The input monitoring can be enabled by the following way:
manually by ENABLE command of the network controller (S2000M panel v.4.13 (3.13)
and higher);
manually by ARM or ENABLE command of the network controller (S2000M panel v.4.12
(3.12) and lower)
manually using the Signal-20M controls when operated in combination with the S2000M
control panel v.4.12 (3.12) and lower;
manually using the Signal-20M controls, in standalone operation.
The input enablement can be done manually only using the Signal-20M own controls or by a
command of the network controller.
If during an arming attempt, the input resistance is less than normal, for example, a smoke detector
triggering occurred in the input circuit, the control panel automatically resets input (turns off the power of
this input for 3 seconds). This allows automatic current-consuming detectors to be returned to the
quiescent mode.
The device starts evaluating the input resistance after a delay equal to the value of the
Delay
Analysis after Rese
t parameter. If after the power reset, the resistance of the loop is not within the
normal range, the input goes into the
ARMING FAILED
If input resistance is higher than normal range at the arming attempt, the input immediately goes to
the
ARMING FAILED
status.
Being in
ARMING FAILED
state, the input can go to the following states:
–
-
DISARMED
- manually, using the device controls or by the command of the network controller;
–
-
ARMED
:
manually using the device controls or by the command of the network controller;
automatically when the configuration parameter
Reaming If Arming Failed
is enabled, if
the input resistance is in the normal range.
