15 Amended: April 22EMEA Fire Technical Support: DF6000/CF3000 Applications GuideDouble Knock.Double knock operation is programmed on site installer and is used to prevent unnecessaryevacuation of the site. Two fires are needed from the selected list before the output condition issatisfied and the output can operate. A Delay time cannot be used on stage 1 at the same time asDouble Knock. Version 3.0.8.12 (Aug 20) forbids this by only allowing either to be selected.The operation can be done by address, zone or global. Later versions have included the opportunityto double knock WITHIN an individual zone (any zone 2 devices)When selecting the trigger to be by address all the addresses have to be on the same loop and thelimit is sixteen.When selecting the trigger to be by zone, then the limit is sixteen zones, (or groups) in each stage.Selecting by zone means that two different zones will have to be in fire before the output condition issatisfied.When selecting the trigger to be global then any two fires on that panel or network will satisfy theoutput condition.If a Cascading timer is used (Release Feb 2015) any outputs using DN global will respond on the firstcascade. If DN global is required use DN any zone group and choose all zones except the cascadetimer zone.NOTE If Double knock is set by zone – any 2 devices within the same zone will NOT satisfythe condition.Coincidence (Dependency type C).Coincidence is different from double knock in that two fires from the allocate device list are required tosatisfy the output condition but one fire from outside the list will also satisfy the output condition.This function is similar to double knock in the way that it is set up i.e. by address, by zone and has thesame restrictions on the number of trigger devices.NOTE If Coincidence is set by zone – any 2 devices within the same zone will NOT satisfy thecondition.Sounder Level Test.This option allows for db readings to be taken without causing too much disruption to the siteoccupants.Selection of the sounder level test mode turn the sounders on for 15 seconds enabling a reading to betaken and then turn them off for 30 seconds allowing the engineer to move on to the next area.
