Field Wiring Indicating Circuit Wiring The MR-2320 Series Fire Alarm supports Class B or Style Y and Class A Style Z wiring for its indicating circuits. Each circuit is supervised by a 3.9KΩ EOL resistor or active EOL module. Each indicating circuit provides up to 1.7 A, 5 A maximum total if no auxiliaries are used.
MR-2320 Series Installation and Operation Manual Releasing Circuit Wiring Wiring for the releasing circuit is shown in Figure 14, below. SIG3 and SIG4 output circuits are reserved for the releasing circuits. Solenoid EOL module (MP-320R/W) is used to supervise the solenoid coil. If the solenoid is already fitted with the directional diode then only the 3.9KΩ EOL resistor is used. The supervisory current passes through the solenoid coil thus confirming the integrity of the solenoid coil for open coil.

MR-2320 Series Installation and Operation Manual System Checkout Before turning the power “ON” To prevent sparking, do not connect the batteries. Connect the batteries after powering the system from the main AC supply. 1. Check that all modules are installed in the proper location with the proper connections. 2. Check all field (external) wiring for opens, shorts, and ground. 3. Check that all interconnection cables are secure, and that all connectors are plugged in properly. 4.
Indicators, Controls and Operations Indicators, Controls and Operations Refer to Figure 20 below for LED Indicator and Control Button locations.
MR-2320 Series Installation and Operation Manual COMMON ALARM The common alarm led is illuminated steady red as a result of any active alarm present in the system. COMMON TROUBLE The common trouble led in illuminated steady amber as a result of a trouble condition being detected on the system. BATTERY TROUBLE Flashes amber at a slow rate, when the battery voltage is lower than the specified threshold or the battery is off line.
Indicators, Controls and Operations Menu Buttons To use the menu buttons you will need to install the CFG-300 configuration tool. See Using the CFG-300 Tool on page for details. M Menu Button Pressing M and entering the passcode will allow you to enter the command menu. ? Info Button When the system is off-normal, press ? to display extra information of the event. Enter Button Pressing this button to select a menu option or to confirm a menu operation.
MR-2320 Series Installation and Operation 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.
Indicators, Controls and Operations When an Initiating Circuit Disconnect pushbutton is returned to the normal state (by pressing it again in order to unbypass the circuit), the panel checks the state of the circuit. If the circuit is active, the Status Indicator flashes for 10 seconds at the Fast Rate without processing the input. If the Circuit is not re-bypassed by then, it will be processed as a new input.
MR-2320 Series Installation and Operation Manual of Abort Delay in the configuration. When the release timer expires, the corresponding releasing circuit is activated. When the panel is in normal condition, activation of the Abort Switch will cause a trouble signal and the corresponding zone amber LED turns on at slow flash rate. Manual Release Switch Activation of the Manual Release Switch of a hazard area will activate the corresponding releasing circuit.

Operating the Panel Operating the Panel Panel Operation During Various Hazard States The escalating hazard zone states include Idle, Alert, Alarm and Release. They are defined based on the status of Hazard Area input zone(s), correlated Abort Switch and Manual Release Switch. Hazard Idle • No correlated alarm zone active. • Release Timer is not started. • Manual Release Delay Timer is not started. • Abort Switch is off. • Manual Release Switch is off. • Corresponding NAC circuit is off.
MR-2320 Series Installation and Operation Manual General Panel Operation • Activation of Manual Release Switch starts the Manual Release Delay Timer. The expiration of Manual-release Delay Timer (MDT) activates the releasing circuits consequently. Manual Release Switch overrides the Abort Switch always and Manual-release Timer (MDT) always overrides Release Timer (RT).
