Switch Functions in Normal Mode

Acknowledge
An Acknowledge key is located on the MS-2410BC keypad (refer to Figure 4-1), and may be remotely located on
any of the LED-10 annunciators, the LDM graphic annunciators, or the AFM series annunciators. The Acknowl-
edge key silences the system piezo sounders and changes all flashing system LEDs to steady. Pressing the
Acknowledge key will have no effect on the Notification Appliance Circuits.
Signal Silence
A Signal Silence key is located on the FACP keypad (illustrated in Figure 4-1), and may be remotely located on
any of the LED-10 annunciators, the LDM graphic annunciators, or the AFM series annunciators. If any of the
Signal Silence keys are pressed, the following will occur:
The silenceable Notification Appliance Circuits will be turned OFF
The main circuit board Signal Silence LED will be turned ON
The system piezo sounders are turned off
Upon the occurrence of a subsequent event (alarm or trouble), Signal Silence is overridden and the control panel
will respond to the new event. The Signal Silence keys will be ignored for nonsilenceable waterflow type alarms.
Drill
A Drill key is located on the FACP keypad, and may be remotely on any of the LED-10 annunciators, the LDM
graphic annunciators, or the AFM series annunciators. To perform a drill from any of these devices, the Drill key
must be pressed and held for more than two seconds (time to prevent accidental activation). The MS-2410BC
turns on all NACs and turns off the Signal Silence LEDs if they were on. The alarm relay is not activated during a
drill. The Signal Silence keys will silence all silenceable NACs during a fire drill and the Reset key will restore the
FACP to Normal Mode.
