4.5 General Alarm 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, the SIGNAL SILENCE button silences the stage 1 and stage 2 alarms.
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 configured as a two-stage system, pressing the AUTOMATIC ALARM SIGNAL
CANCEL (Acknowledge) button while the Auto General Alarm timer is running (there is an alarm in
the panel, but it is still in the first stage), cancels the timer and illuminates the amber AUTOMATIC
ALARM SIGNAL CANCEL LED steadily, thereby acknowledging the alarm.
If the Panel is not configured as a two-stage system, this button becomes ALM/SUP/TBL/BLDG
AUDIBLE SIL (buzzer silence). Press ALM/SUP/TBL/BLDG AUDIBLE SIL to silence the buzzer.
Press the GENERAL ALARM button to immediately send the panel into General Alarm or total
evacuation. It also re-activates the signals if they have been silenced during General Alarm. The
General Alarm condition remains active until the SYSTEM RESET button is pressed.

5.0 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.

6.0 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 are colored either amber, red, or green.
When lit, LEDs provide information regarding the status of the panel.
Property and Building Safety 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.

17
Glossary
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.
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.
