8.7 OUTPUT DELAY DISABLEMENT
• Function : This option offers the user the ability to override the output delays programmed within the
system and activate the outputs immediately that there is a fire alarm. This option should be
used with care since removing the delays could interfere with the planned building
evacuation procedure.
The majority of 6400 systems have delays programmed. Typically these are used to give
time to investigate a fire before evacuating the building and signalling to the fire brigade.
To indicate that there are delays and therefore that the outputs are prevented from
activating immediately, the ‘Output Delay’ and the ‘Disablement’ LEDs will be lit.
• Disable Output Delay (ie enable the outputs immediately that an alarm occurs):
If there are delays programmed within the system then pressing option ‘6’ when offered the option
to ‘Disable Output Delay’ will override those delays.
Having removed the delay so that the outputs are free to activate immediately the ‘Output Delay’
LED will be extinguished. In addition if this was the only Disablement then the ‘Disablement’ LED
will also be extinguished.
• Warning : Once the delays have been overridden and the leds extinguished then there is no indication that the
panel is no longer operating in its intended mode.
