How to Program a Second Shot Switch
Note: The Second Shot switch can only be used with the MAN REL DELAY Type Code.
The following contains information needed to program a Second Shot switch for a monitor module.
Description A monitor module—connected to a UL-listed manual station (such as the
NBG-12LRA)—used as for a second release of agents. A Second Shot switch
overrides a Delay Timer programmed to the same Releasing Zone.
Program Select a monitor module for the manual release function. While programming the
module (refer to "Module Point" on page 40 for instructions)
1. Select the
SECOND SHOT Type Code.
2. Enter the number of the desired releasing zone into the module’s zone map. The
releasing zone must be fully programmed (refer to "Releasing Zone" on page 46).
Example
A programming example of a monitor module programmed as a MAN REL DELAY switch for the
first shot and a
SECOND SHOT switch for the second shot.
Appendix Figure B-13 Monitor Module Configured as a Second Shot
Switch
With two monitor modules configured as shown above, program releasing zone ZR05
for the following releasing selections: Delay Time = 15, Abort Switch = ULI, Cross
Zone = Y, Soak Time = 30
ZR05 can be activated in one of two ways, as described in the examples given below.
Example 1: If the detector initiates the alarm, ZR05 activates. Releasing begins after
the delay timer has expired (15 seconds). Releasing will continue for the soak timer
duration (30 seconds). The Second Shot switch can then be activated, and will remain
activated for as long as the switch is held on. Second Shot releasing will end when the
switch is no longer held on (behaving like a tracking function).
Example 2: If the NBG-12LRA (Type Code
MAN REL DELAY) lever is pulled, the delay
timer begins its 15 second countdown. Releasing will begin after the delay timer has
expired, and will continue for the soak timer duration (30 seconds). The Second Shot
switch can then be activated, and will remain activated for as long as the switch is held
on. Second Shot releasing will end when the switch is no longer held on (behaving like
a tracking function).
