Can L5100 go off sooner than 30 secs after door opens?

When you program your Honeywell 5811 wireless door and window sensor to a Honeywell L5100 LYNX Touch control panel, one of the settings you must choose is the Response Type. The Response Type for a zone tells the panel how to react when that zone is activated. When you choose 'Door' as your Device Type on a L5100 panel, the system automatically limits the available Response Types to the ones you would want to use for door sensors.

You can choose between Entry Exit 1, Entry Exit 2, Perimeter, Resident Monitor, Resident Response, General Monitor and General Response. While there are multiple options, the vast majority of 5811 door sensors get programmed as Entry Exit 1 or Perimeter. These two Response Types are by far the most commonly chosen option so all you need to do is decide which to pick.

For doors that you use when the system is armed, you should choose Entry Exit 1. For doors that you will never open when the system is armed, you should choose Perimeter. When you choose Entry Exit 1, a 5811 activation will initiate the programmed Entry Delay 1 timer. The default Entry Delay 1 timer is thirty seconds but it can be changed. This delay allows a user to enter the home while the system is armed without activating an alarm. As long as you get to the panel and disarm it before the timer ends, no alarm is activated. You want to keep the zones on delay to a minimum because you don't want to give an intruder extra time to break in before the alarm will activate. Therefore, all doors you don't use when the system is armed should be programmed as Perimeter. When Perimeter zones are activated, the alarm is tripped right away.

These Response Types hold true for all Honeywell security systems so if you have a door sensor that takes thirty seconds to sound an alarm after activating, you shuold switch it to Perimete. Unless of course, it is one of the door you enter when you are coming home and the system is armed.
