Voltage timing for AC-3 output.
If the voltage was present at the AC-3 output, it disappears after a fire alarm occurred for its
duration, but not shorter than T2+T3 (see the description of the times of the AC-1 output). The
response to a fire alarm always takes place with a delay of ~2s required for its correct recognition. The
voltage recovery at the AC-3 output is possible when the mains present and when is no fire alarm. The
voltage on this output is additionally maintained also after the mains power failure in the absence of a
fire alarm, so as not to unnecessarily move the devices to the position appropriate for the fire alarm
only due to the power failure. The voltage maintenance in this state is limited by the maximum battery
life T1.
When switching from the mains to the inverter operation, there is a temporary voltage drop on the
output (about 150ms).
Outputs AC-4A and AC-4B
The AC-4 output is intended for devices that should start operating with some delay after a fire
alarm, e.g.
-
smoke exhaust fan, which can be activated only after passing the shut-off valve to the fully
open position;
-
self-braking, two-way actuator of fire ventilation shutting-off damper, which should close the
damper only after stopping the fan.
-
cascade-operated devices to reduce the inrush current.

Time waveforms for AC-4 output.
The AC-4 output has the AC-2 output functionality. The only difference is the additional delay in
switching after the fire alarm is recognized by the T3 time (see the description of the times for the AC-
1 output).
The response to a fire alarm always takes place with a delay of ~2s required for its correct
recognition. If the fire alarm occurred with the inverter turned off, it will be restarted with an additional
delay of about 10s.
