APPENDIX - H: OUTPUT FEATURES
Output Activation- and Deactivation- Delays
Each output device has a selection for Activation delay and Deactivation delay when it is
installed in the configuration. The Activation delay refers to the delay in which the output will
activate after the reception of its activation command. If the Activation delay is set to 0 (default
setting), the output immediately activates. The Deactivation delay refers to the delay in which
the output will deactivate after the reception of its deactivation command. If the Deactivation
delay is set to 0 (default setting), the output immediately deactivates.
Output device during activation delay will not respond to deactivate command. This means an
output device with activation delay will definitely be activated after receiving activate command.
Output device during deactivation delay will respond to activate command immediately and the
deactivation delay will be cancelled.
Assuming an output channel on SLC is configured to be interlocked by supervisory condition of
FACP with Activation Delay of 10s and Deactivation Delay of 10s. When FACP enters
supervisory c
ondition at 00”00’, the output channel will be activated at 00”10’. Then if the
supervisory condition goes at 00”30’, the output channel will be deactivated at 00”40’.
