2.0 Main Display
Figure 1 shows the LCD display, LED indicators, and control buttons locations.
Figure 1 Main Display
The main display panel on the fire alarm control board consists of:
• Five LED indicators (located just below the LCD screen)
• Five buttons (left edge of display)
• 16 program buttons (right part of display)
LED indicators may be amber, red, or green, and may illuminate continuously (steady), or at
one of two flash rates:
•Fast flash (supervisory): 120 flashes per minute
•Trouble flash (trouble): 20 flashes per minutes

3.0 The Buzzer and LED Indicators
Figure 2 LED Indicators
3.1 Buzzer
The buzzer sounds if there is a fire alarm, a supervisory alarm, or a trouble in the fire alarm
system. It turns off if the condition causing the buzzer to sound is cleared or if the BUZZER
SILENCE button is pressed.
3.2 A.C. On LED
The green A.C. On LED illuminates steadily as long as the main power is above minimum
level. The indicator turns off when the level falls below the minimum level and the panel
switches to standby (battery) power.
3.3 Alarm LED
The red Alarm LED illuminates steadily when there is a fire alarm. This indicator will remain on
until the system is reset.
3.4 Supervisory LED
The amber Supervisory LED illuminates at the fast flash rate when there is a supervisory
alarm in the fire alarm system. For non-latching supervisory alarms, the Supervisory LED will
turn off when the condition causing the alarm goes away. For latching supervisory alarms, this
LED remains on until the panel is reset.
3.5 Trouble LED
The Trouble LED flashes amber at the trouble flash rate when the panel detects any trouble
condition. For non-latching trouble conditions, the Trouble LED turns off when the condition
causing the alarm goes away. For latching trouble conditions, the LED remains on until the
panel is reset.
3.6 CPU Fail LED
The CPU Fail LED flashes amber at the trouble flash rate to indicate a microprocessor failure
on the main board.

4.5 BUZZER SILENCE
The SYSTEM RESET button resets the fire alarm control panel and all
circuits.
Pressing the SIGNAL SILENCE button when the panel is in alarm deactivates
any silenceable signal devices in the fire alarm system. Non-silenceable
signal devices are unaffected. If you press the SIGNAL SILENCE button a
second time, or if there is a subsequent alarm, the signals will re-sound. If the
panel has been configured with a Signal Silence Inhibit timer, this button will
not work until the timer expires. This button also does not work if you have
pressed the FIRE DRILL button.
Pressing the FIRE DRILL button simulates a fire alarm by activating the fire
alarm signals without transmitting an alarm to the central station. To cancel
the fire drill, press the button again. If the fire alarm system goes into a real
alarm while you are performing a fire drill, this button will not turn off the
signals or operate any programmed relays.
Pressing and holding the LAMP TEST button causes all the front panel LEDs
to illuminate. The screen displays the software version and the buzzer
sounds. Use this button to test that the LCD display and all LEDs on the main
display are working. If you hold the LAMP TEST button for more than ten
seconds, the common trouble is activated.
Pressing the BUZZER SILENCE button while the buzzer is sounding silences
the buzzer. The buzzer will resound if there is a subsequent event. Pressing
the button when the buzzer is not sounding has no effect.

6.0 Understanding On-screen Messages
The screen of the fire alarm control panel displays messages regarding system events.
System events display on the screen in a queue. Events in this queue are listed on the screen
in order of priority: alarms are of highest priority, followed by supervisory, trouble, and monitor
conditions. If the same type of event happens more than once (for example, two trouble
conditions occur) they will be listed in the order of the most recent event to the least recent
event. If an alarm, supervisory, or trouble condition occurs, their respective LED will flash
Scroll through the events by using the and arrow buttons. If you need more
information about a displayed event, press .
6.1 Example 1 (detection circuit)
Figure 3 indicates that event 1 of 9 is an open trouble at the East Lobby Entrance. When
is pressed, the screen shows that the process type is a verified alarm on Z-01 and the
event occurred on Tuesday April 4, 2003 at 18:01.

7.0 Glossary
Alarm Condition
Occurs when devices such as detectors, pull stations, or sprinklers are activated. In a single
stage system, this condition activates all signalling devices throughout the building. In a two
stage system, this condition activates an alert signal and the General Alarm timer.
Circuits
Refers to an actual electrical interface and is classified as initiating (detection), indicating
(signal), or relay. The terms “circuit” and “zone” are often used interchangeably in the fire
alarm industry.
Fast Flash Rate
An LED flashes at 120 flashes per minute to indicate a supervisory alarm.
Indicating Circuit
A circuit in a fire alarm system that is connected to audible or visual signalling devices.
Initiating Circuit
A circuit in a fire alarm system that is connected to detectors, pull stations, sprinklers, or water
flow switches.
Latching Circuit
A circuit that, when activated, will cause a condition on the panel that cannot be cleared until
the panel is reset.
LED
The light-emitting diodes (LEDs) of the MR-2300 are colored either amber, red, or green.
When lit, LEDs provide information about the status of the panel.
Monitor Condition
Occurs when dampers open or close, when supply and return fans are running, etc.
Non-latching Circuit
A circuit that, when activated, causes a condition on the panel that is cleared once the circuit is
deactivated. This term is used to describe supervisory and trouble circuits.
Non-Silenceable Circuit
A signal circuit that cannot be silenced by pressing the SIGNAL SILENCE button.

19 (20)
Glossary
Relay Circuit
A circuit in a fire alarm system that connects relay devices (for example, fan damper relays).
Remote Annunciator
A device that visually indicates, either by LCD or LEDs, the floor or zone where the alarm
originated.
Silenceable Circuit
A signal circuit that can be silenced by pressing the SIGNAL SILENCE button.
Supervisory Condition
Occurs when the system detects open circuits, short circuits, and grounds. A supervisory
condition is one that would interfere with the operation of the fire alarm system.
Trouble Condition
Occurs when an abnormal condition such as a problem in the wiring, battery or power circuits
exists in the fire alarm system.
Trouble Flash Rate
An LED flashes at 20 flashes per minute to indicate a trouble condition.
Walk Test
A test performed by a technician to ensure that each detection device is connected to the
panel and working properly.
Zone
A fire alarm protected area that consists of at least one circuit. The terms “circuit” and “zone”
are often used interchangeably in the fire alarm industry.
