Common Controls; Circuit (Zone) Disconnect Buttons - Secutron MR-2100 Installation Manual

Output Circuits Bypass Switch
The output circuit bypass switches bypasses the NAC circuit and the releasing circuit. The switch is a toggle switch
and pressing it again, will un-bypasses the output circuit the trouble LED turns off.

Common Controls

System Reset Button
The System Reset button resets the Fire Alarm Control Panel and all Circuits. In particular, the system reset button
• Resets all Latching Trouble Conditions
• Resets all Initiating and Releasing Circuits
• Resets 4-Wire Smoke Supply
• Turns off all Indicating Circuits
• Turns off Signal Silence Indicator
• Stops and resets all Timers
• Processes inputs as new events
• Does not affect Aux Disconnect
Signal Silence Button
Activation of the Signal Silence button when the panel is in alarm turns on the Signal Silence indicator and
deactivates any Silenceable Indicating Circuits. Non-Silenceable Circuits are unaffected. Signals will re-sound upon
any subsequent alarm. Subsequent operation of signal silence resounds all Silenceable signals. This button does
not function during any configured Signal Silence Inhibit Timer period.
Auxiliary Disconnect Button
Activating the Auxiliary Disconnect button activates the Auxiliary Disconnect function. The Auxiliary Alarm Relay is
always disconnected with this button. The Common Alarm Relay, the Common Supervisory relay and all correlated
alarm relays may be disconnected as selected through configuration. Activating the Auxiliary Disconnect button
also causes the Common Trouble LED to illuminate steady, the common trouble relay to send a trouble message
and the trouble buzzer to flash at the trouble flash rate. Pressing the Auxiliary Disconnect button again de-activates
this function and the system will go back to normal.
Lamp Test Button
Activation of the Lamp Test button causes all front panel Indicators to steadily illuminate and turns the buzzer ON
steady. If Lamp Test is active for more than 10 seconds, Common Trouble is activated.
Buzzer Silence Button
Activation of 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 pushbuttons are provided for all initiating indicating, and releasing circuits on the Fire
Alarm Control Panel. These pushbuttons are located beside their respective indicating LED.
Pressing a Circuit Disconnect pushbutton bypasses the associated circuit and turns on its Trouble Indicator,
activating Common Trouble. Pressing a releasing circuit disconnect pushbutton bypasses the associated releasing
circuit and turns on its LED, activating common supervisory. While a Circuit is disconnected, all changes in status
(alarms and troubles) on that circuit are ignored. The panel does not activate disconnected indicating circuits.
Circuit Disconnect pushbuttons are toggle switches; therefore, pressing an activated switch a second time will un-
bypass (reconnect) the circuit.
Disconnecting an active Latching Initiating Circuit (including Alarms, Water flow Alarm, Sprinkler Alarm, General
Alarm, and Latching Supervisory) does not affect its status until the panel is reset. Disconnecting an active Non-
Latching Initiating Circuit (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.
