How to Program a Second Shot Switch
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 Section 3.4.2, “Module Point”, on page 46 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 Section 3.4.4, “Releasing Zone”, on page 50).
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.
Figure B.12 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).
NOTE: The Second Shot switch can only be used with the MAN REL DELAY Type Code.
