I am facing one of the trouble in AFP200

Fire Alarm Help
1

One of the diesel generator have a suppression system co2. This case there are 2 smoke detectors, 2 h2s detectors, 1 UV/IR and one manual alarm point this are the inputs.
When we get inputs from any one of the detectors normally the SOV will activating and the co2 will released.
But here getting all inputs and get alarm in panel but not getting corresponding output for SOV ( SOV not activating )

Anybody ideas what is the reason?

Are you sure that the system releases on just one detector alarm? Many times detectors are cross-zoned so that one will alarm, but it takes a 2nd detector to release. Is the output on the panel not working or the release solenoid? Also, does it have a timer that delays the release for 30 seconds?
