Operation

2.2

2.2.1 Key-switch

The key-switch is used to enable

and disable the operation of the

function switches if switch 2 on

DIP switch SW1 has been placed

to the On (Down) position.

To enable the Acknowledge,

Silence, Drill and Reset function

switches, insert a standard

Fire•Lite key into the key-switch

located at the top right corner of

the LCD-40. Make certain the

key is inserted completely before

attempting to turn it. Turn the key

clockwise until it stops. Leave the key inserted while pressing the

function switches. When finished with the function switches, turn

key-switch counterclockwise to disable function switches.

Note that the key-switch should normally be in the disabled position

(fully counterclockwise), with the key removed and access to the key

restricted to authorized personnel only. Do not leave the key unat-

tended in the LCD-40.

2.2.2 Acknowledge

When the Acknowledge switch is pressed and released, the LCD-40

sends an Acknowledge command to the control panel. Pressing the

Acknowledge switch silences the local piezo sounder, the sounders

located in all other system annunciators and the sounder located on

the Fire Alarm Control Panel's main circuit board. It will also

change all flashing system LEDs to steady on. Only one press is

necessary regardless of the number of new alarms, troubles or super-

visory signals.

An acknowledge message is also sent to the printer and the history

files in the MS-9200. Multiple active events (alarms, troubles,

supervisories) are scrolled on the display at a one second rate, but

may be held for sequential display by pressing and holding the

Acknowledge switch.

When more than one event exists, the first press of the Acknowledge

switch silences system piezo sounders and changes all flashing
