(battery) power.
The red Common Alarm LED will illuminate steadily whenever there is a fire alarm. If the panel is
set for two stage operation, pressing the red General Alarm button will also turn on the Common
Alarm indicator. This indicator will remain on until the system is reset.
The amber Common 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.
The amber Common Trouble LED flashes at the trouble flash rate when the panel detects any
trouble condition. For non-latching trouble conditions, the Common Trouble LED will turns off when
the condition causing the alarm goes away. For latching trouble conditions, this LED remains on
until the panel is reset.
The amber Remote Trouble LED flashes at the trouble flash rate if the panel detects a trouble at the
City Tie or UDACT module, communication trouble with a remote annunciator, or a local trouble at a
remote annunciator.
The amber Fire Drill LED illuminates steadily after you press the Fire Drill button. This LED remains
on until you press the Fire Drill button again.
If the panel is configured as a two-stage system, the amber Acknowledge LED flashes at the fast
flash rate while the Auto General Alarm timer is timing out. The Acknowledge indicator illuminates
steadily when the General Alarm timer is cancelled by the pressing of the Acknowledge or Signal
Silence buttons. If the Auto General Alarm timer times out and puts the panel into general alarm,
this LED turns off.

Fire Drill Button
Acknowledge Button
General Alarm Button (or Info button for single stage system)
Auxiliary Disconnect Button
Lamp Test Button
Buzzer Silence Button
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 times out. This button also does not work if you have pressed the Fire Drill button.In a two
stage system, if the Auto General Alarm timer has timed out, this button also performs the same
function as the Acknowledge button.
Pressing the Fire Drill button will simulate 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 activate any programmed relays.
If the panel is not configured for two-stage operation, this button is not active. If the panel is
configured for two-stage operation, pressing the Acknowledge button while the Auto General Alarm
timer is timing (there is an alarm in the panel, but it is still in the first stage), the timer is cancelled
and the amber Acknowledge LED illuminates steadily.
If the panel is not configured for two-stage operation, this button is not active. If the panel is
configured for two-stage operation, pressing the General Alarm button immediately sends the
panel into second stage general alarm. It will also re-activate the signals if they have been silenced
during general alarm. The general alarm condition remains active until the panel is reset.
Pressing the Auxiliary Disconnect button activates the auxiliary disconnect function. Pressing the
button again de-activates this function.
Pressing and holding the Lamp Test button causes all front panel LEDs to illuminate and sounds
the buzzer. Use this button to test that all LEDs in the main display are working. If you hold the
Lamp Test button for more than ten seconds, the Trouble LED will illuminate.
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.

Circuit (Zone) Disconnect Buttons

Circuit (Zone) Disconnect Buttons
Circuit (zone) disconnect buttons are provided for all initiating and indicating circuits on the fire alarm control panel.
These buttons are located beside their respective indicating LEDs.
Pressing a circuit disconnect button disconnects that circuit from the system and turns on its trouble indicator. While
a circuit is disconnected, the panel will ignore all changes in the status (alarms and troubles) of that circuit. Circuit
disconnect buttons are toggle switches; therefore, pressing an activated button a second time will reconnect the
circuit.
Disconnecting an active latching initiating circuit such as alarms, water-flow alarm, sprinkler alarm, general alarm,
and latching supervisory does not affect its status until the panel is reset. Disconnecting active non-latching initiating
circuits including non-latching supervisory and trouble-only causes them to behave as if the alarm situation has
disappeared. Disconnecting an active indicating circuit immediately deactivates the circuit.
When an initiating circuit disconnect button is pressed a second time, the panel checks the state of the circuit. If the
circuit is active and will cause a false alarm, the Status LED flashes for ten seconds at the fast flash rate (red for
alarm or amber for supervisory) without processing the input. If the circuit is not re-disconnected by then, it will be
processed as a new input.

Glossary
Alarm
Condition Occurs when devices such as detectors, pull stations, or sprinklers are activated.
In a single stage system, this condition will activate all signalling devices
throughout the building. In a two stage system, this condition will activate an alert
signal and the General Alarm timer.
Circuits Refers to an actual electrical interface and can be 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 120 flashes per minute is the rate at which an LED will flash to indicate a
supervisory alarm.
General Alarm
Timer In a two stage system, the general alarm timer begins timing when the panel is in
the alert stage. When the general alarm timer times out, the system will go into a
general alarm, where all signals in the building will sound.
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, or
sprinkler 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-2306 ar colored either amber, red, or
green. When lit, LEDs provide information regarding 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, will cause a condition on the panel that will be
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.
Relay Circuit A circuit in a fire alarm system that connects relay devices (e.g. fan damper relays,
etc).
Remote
Annunciator A device that visually indicates, either by LCD or LEDs, the floor or zone where the
alarm originated.
Single Stage
System A type of fire alarm system that immediately sounds all the signals throughout the
building when an alarm is detected in any part of the system.
Silenceable
Circuit A signal circuit that can be silenced by pressing the Signal Silence button.

Glossary
10
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 20 flashes per minute is the rate at which an LED will flash to indicate a trouble
condition.
Two Stage
System A type of fire alarm system that causes an alert signal to sound when an alarm is
detected in any part of the system. An alert signal advises designated persons of a
fire emergency. If the alert signal is not acknowledged within five minutes of its
initiation, an alarm signal will automatically sound throughout the building.
Walk Test A test performed by a technician to ensure that each detection device is connected
to the panel and working properly.
Zones 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.
