In order for the Suppression Release function of the 4010 to work correctly you
must follow certain steps.
Step Description
1
Assign the appropriate point types to your Suppression Release
monitoring devices.
2
Add the points in Step 1 to the appropriate Suppression Release lists.
3
Assign the appropriate point types to your Suppression Release NACs.
4
Add the NACs in Step 3 to the appropriate Suppression Release output
list.
Use the following information to program the 4010 for Suppression Release
functions. After you are finished programming for suppression release, the 4010
is set up for the default values for delay and dual detector operation. In the
following example, a TrueAlarm point is used.
Note 1. Do not use the PC Programmer to change the point type of a
suppression release point; doing this causes the PC Programmer to change the
point type back to its default setting. To change the point type of a suppression
release point, you must use the front panel programmer.
Note 2. Set the Depleted Battery Cutout (discussed earlier in this chapter) to
ON for suppression release systems.
In the following example, the list definitions are as follows. Refer to Appendix
B for specific List definitions.
- L9 Automatic Suppression Release Points
- L10 Suppression Manual Release Points
- L11 Suppression Release Abort Points
- L12 Suppression Release Output Points
For example: any points in L9 have a default delay of 60 seconds before L12
activates, any points in L10 have a default delay of 30 seconds before L12
activates. Once points in L10 are activated, L12 activates after the default 30-
second delay regardless of the state of abort switches in L11. When Dual
Detector operation is ON, this requires two points in L9 to activate before
suppression release operation is initiated.
WARNING: When any points in L11 are activated during the
cycling of a delay function, the delay timers continue
to count down to zero. If you release the abort
switch that is in L11 after the timer has reached zero,
points in L12 activate immediately.
