Section 2 Switch Functions

Acknowledge/Scroll Display.

This silences the piezo

sounder and changes all flashing conditions to steady. Only one press
is necessary, regardless of the number of new alarms, troubles, or
supervisory signals. If the piezo is silenced, it sends an acknowledge
message to the printer and history file. Acknowledge also automati-
cally sends a special command to silence piezo sounders on the
FDU-80 and ACS-series annunciators.

Signal Silence.

S

IGNAL

S

ILENCE

performs all the functions of

A

CKNOWLEDGE

. In addition, if an alarm exists, it turns off all silence-

able circuits and illuminates the S

IGNALS

S

ILENCED

indicator. It also

sends a S

IGNALS

S

ILENCED

message to the LCD display, printer, and

history file. A subsequent alarm will then resound the system.
Notes:
1. This unit is programmed to inhibit signal silence for ____seconds.
2. This unit is programmed to automatically silence alarm signal after

_____ minutes.

Drill.

The NFS2-640/E waits for the Drill switch to be pressed for

2 seconds (to prevent accidental activations), then turns on all silence-
able circuits (all FCM-1 modules/bell circuits that are programmed
silenceable), and turns off the Signals Silenced LED. It sends a Drill
Activated message to the LCD display, FDU-80, printer, and History
file.

System Reset.

Resets the control panel in standalone applica-

tions. Resets panel when enabled in network applications.

Lamp Test.

Press and hold the switch to lamp-test the LEDs.

Section 3 LED Indicators

Controls Active.

assumes control of local operation as primary display; turns off when
another panel assumes control of local operation.

Power.

Green LED which illuminates when primary power is

applied to the control panel.

Red LED lights when any of the releasing zones

have been activated, but have not yet discharged a releasing agent;
turns off when no releasing zones are in the pre-discharge state.

Discharge.

Red LED lights when any of the releasing zones are

active and in the process of discharging a releasing agent; turns off
when no releasing zones are discharging a releasing agent.

Abort Active.

Yellow LED lights when an abort switch has been

activated; turns off when an abort switch has been pressed and its
timer is still counting down. Activation of a Manual Release Switch
will override Predischarge Delay and override an active Abort Release
Switch, resulting in an immediate agent release.

Section 5 Periodic Testing and Maintenance

To ensure proper and reliable operation, system inspection and testing
should be scheduled monthly, or as required by NFPA 72 or local fire
codes. A qualified Service Representative should perform testing.

Before Testing:

Notify fire department and/or central alarm

receiving station if alarm condition is transmitted. Notify facility per-
sonnel of the test so alarm sounding devices are ignored during the test
period.

After Testing:

Notify all fire, central station, and/or building per-

sonnel when testing is complete.
