How to Program a Second Shot Switch
Note: The Second Shot switch can only be used with the MANREL 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.
How to
program
1. Select a monitor module (refer to “How to Modify or Delete a Point (2=point)” on
page 21) that you want to use for the manual release function.
2. Select the
SECOND SHOT Type Code.
3. Select the Releasing Zone (R0-R9) for your releasing application.
4. Press the
ENTER key to save, then press the ESC key until you return to the Program
Change screen.
Example
A programming example of a monitor module programmed as a MANREL DELAY switch for
the first shot and a Second Shot switch for the second shot.
Figure 15 Monitor Module Configured as a Second Shot Switch
With two monitor modules configured as shown above, program Releasing Zone R5
with the following releasing selections.
R05 can be activated in one of two ways, as described in the examples given below.
Example 1: If the detector initiates the alarm, R05 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
MANREL 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).
