Switch Functions in Normal Mode
SILENCE
Silence switches may be located on the FACP keypad (illustrated in Figure 4-1), any of the ten zones programmed
as a remote silence switch, remotely located on any of the LED-10 Series annunciators, the LDM graphic annun-
ciators, or the AFM series annunciators. The Silence Switch performs the same functions as the System
Acknowledge switch. In addition, if any of the System Silence switches are pressed, the following will occur:
✓
The silenceable Notification Appliance Circuits will be turned OFF
✓
The main circuit board silence LED will be turned ON
✓
The SILn message will be displayed (where n = NAC #)
✓
The system piezo sounders will be shut OFF
✓
'NAC #N Silenced' message will be stored in the History file
✓
'NAC #N Silenced' message will be sent to the printer
Upon the occurrence of a subsequent event (alarm or trouble), System Silence is overridden and the control panel
will respond to the new event. The System Silence switches will be ignored for nonsilenceable waterflow type
alarms.
ACKNOWLEDGE/STEP
Acknowledge/Step switches (Up/Down arrow keys) are located on newer model FACP keypads (refer to Figure 4-
1), remotely located on any of the LED-10 Series annunciators, the LDM graphic annunciators, or the AFM series
annunciators and an option exists that allows any of the ten zones to be programmed to function as a remote
Acknowledge switch.
The Acknowledge/Step switch silences the system piezo sounders and changes all flashing system LEDs to
steady. An acknowledge message is sent to the printer and history files. The Step function permits scrolling
through multiple stored events during normal, history and walktest modes.
When more than one event exists, the first press of the Acknowledge/Step switch silences the system piezo sound-
ers and changes all flashing system LEDs to steady. The second press of the switch stops the scrolling and holds
the event on the display for five seconds. Subsequent pressing of the switch 'steps' through each active event. The
Acknowledge/Step switch must be pressed within 15 seconds to prevent NACs from turning on if alarm presignal
is selected. For additional information on alarm presignal, refer to "Programming Instructions" on page 39.
Note: Software P/N: MS-52102.0 or greater supports the Acknowledge key function at the FACP keypad.
DRILL
Drill switches may be located on any of the ten zones programmed as a remote drill switch, remotely on any of the
LED-10 Series annunciators, the LDM graphic annunciators, or the AFM series annunciators. To perform a drill
from any of these switches, the Drill switch must be pressed and held for two seconds (time to prevent accidental
activation). The MS-5210UD turns on all NACs and turns off the system silence LEDs. The message shown on
the display is dril. The drill message is sent to the printer and history files. The system silence keys will silence
all silenceable NACs during a fire drill.
To perform a drill from the FACP, press the MODE key followed by the code 3745 then press [ENTER/
STORE]. The display will read dril. The alarm relay is not activated. There is an option to transmit the fire drill
report code to the Central Station. During a fire drill, the SILENCE key will silence all silenceable NACs and the
RESET key restores the panel to normal. All zones remain active during a fire drill.
MODE
Pressing the Mode switch followed by a valid 4-digit numerical code and [ENTER/STORE] selects one of the
six modes of operation.
To enter Normal Mode from any other mode press MODE then 6676 [ENTER/STORE].
☛ 6676 spells NORM on a Touch-Tone
1st EVENT
The 1st Event switch along with the Up Arrow and Down Arrow keys, are used to display any presently active
alarm and/or fault conditions present in the system. Press the 1st Event switch at any time to display the first
event (alarm and/or trouble) that occurred.
