10.0 System Delays
Delays may have been programmed into the 6100 at commissioning time to allow a predetermined delay time
from zone activation until,
• The alarm outputs activate
• The fire link activates
Delays may be used in order to allow time for the cause of the activation to be investigated by the premises
management. If the cause of the activation is found to be legitimate the alarm outputs can be manually
activated. If the cause of the activation is found to be false the 6100 can be reset.
The 6100 system set-up chart must be consulted to determine exactly which outputs have been delayed and
how the delay time has been set up.
If the Silence Alarms button is pressed while a delay is running, the alarm outputs will not be activated when
the delay expires. The global fire contacts, however, will still be activated.
Delays only apply to automatic detector activations. A manual activation on a zone
( activating a Manual Call Point ) always overrides all current delays.
11.0 Coincidence Operation
At the time of commissioning, the system may have been programmed to operate in ‘coincidence’ mode.
Coincidence operation is used in order to minimise the effects of false alarms.
Coincidence operation can be used to prevent alarm outputs in certain areas from triggering until two, or more
activations have been received from a certain group of devices.
This allows the initial activation to be investigated before the 6100 activates the full alarm outputs.
