MR-2900 Operator’s Manual

• Non-Reporting: These are non-latching inputs. They are also referred to as Non-Fire.

There is no requirement that these inputs cause any action whatsoever. They use the

supervisory LED for annunciation. They can operate only relays and control modules. The

LEDs, relays and control modules will follow the non-reporting input's status. The LEDs,

relays and control modules operated by non-reporting inputs cannot also be operated by

Fire, Supervisory, Abort or Halt type inputs.

1.3 Status Display

The status display is the top-right section of the front panel. It is visible through the front door. It

consists of the common alarm LED, common supervisory LED, common trouble LED, AC power

LED, and the clock.

The common alarm (red) and supervisory (amber or yellow) LEDs will flash with any new alarm or

supervisory signal. The common trouble (yellow) LED will flash with any new zone trouble or a

new panel trouble, such as low battery, bell trouble, etc. The common LEDs will react to all panel

inputs plus to most conditions it displays from other panels. The AC power (green) LED is lit if AC

power is on. If the AC power has failed, the common LEDs will blink slowly instead of staying on

steady.

The clock shows the current time in 24 hour format. The flashing colon shows that the panel is

functioning correctly. If the AC power is off, the time is not displayed but the colon continues to

flash. The entire clock display flashes if the time has not been set after a Hard reboot of the panel;

also if the time is not set, the panel will show a common trouble. If any memory error occurs

(Program Checksum Error, Database Mismatch, FIFO Overflow, etc.) the clock will display 4

dashes instead of the time. The buzzer will also beep rapidly to indicate the memory error. The

clock will also display 4 dashes if any configuration parameter is changed which requires a Hard

reboot.

1.4 Zone LEDs

The zone LEDs are along the left side of the front panel. They are visible through the front door.

Each zone has an alarm (red), supervisory (yellow or amber), and trouble (yellow) LED. The alarm

and supervisory LEDs will turn on as required by the inputs. The trouble LED will light for either an

input trouble condition, a ground fault or if there is a bypass present. Use the LCD and keypad

(see section 1.8 below) to determine the exact condition. A new condition is shown by a flashing

LED. After the Acknowledge button (see section 1.6 below) has been pressed, the LED will be lit

steadily.

Note: If the buzzer is sounding on the panel, Acknowledge will silence the buzzer, but not latch the

LEDs. Press Acknowledge again to latch the LEDs.

For panels running the MR1 program, each set of zone LEDs corresponds to the input circuit. For

panels running the MR2 program, each set of zone LEDs is programmed via the database to

represent whatever logical zoning is required.

1.5 Buzzer

The buzzer gives audible indication of any new conditions in the panel. It may sound in any of four

modes. Pressing Acknowledge will silence the buzzer. (Acknowledge will need to be pressed

again to latch flashing LEDs.)

The four buzzer modes are:

• Steady: This indicates any new fire alarm conditions. This mode can be disabled in the

database.

• Fast: This indicates any critical failures that must be attended to. These failures can

include, but are not limited to memory overflow, network reboot required, database

mismatch, etc. The pattern in 50ms on/off.
