MR-2900 Operator’s Manual

1.0 Unit Operation

The operation of the MR1 and MR2 programs are almost identical. This chapter applies to both

programs. Those functions that are different are noted.

1.1 Power Up Sequence

The power up sequence of the panel is started in the following ways: power is applied to the panel;

the hard reboot button at the top of the Inner Door is pressed; a Network Reboot command is

issued; or the panel has a fault that triggers the internal watch-dog.

The LCD will first display "INITIALIZING MEMORY PLEASE WAIT". The panel will not respond to

key presses or to zone activity. Once this step is done the panel will start to beep (buzzer does not

sound after a Network Reboot). Press Acknowledge to silence the panel.

Panels running the MR2 program will display the message "LOADING DATABASE PLEASE

WAIT". At this time, the panels will respond to key presses, but not to input circuit conditions.

Note: Since the LCD menu is unavailable, any keys requiring a privilege level other than zero to

be active will be unavailable.

When the initialization is complete, the Main Menu will be displayed on the LCD. At this time the

panel is fully operational.

1.2 Types of Inputs

There are a number of types of inputs that can be used in the system. Each has different uses and

limitations. They are:

• Alarm: This type of input is the normal inputs to the system from smoke detectors, heat

detectors, etc. They are required to activate bells and/or strobes, as well as an LED. They

can optionally operate relays and control modules in a network, as well as releasers on

the same panel. It displays **ALARM** in the Alarm List.

• Pull Station: This type of input is for pull stations. They are required to activate bells and/

or strobes, as well as an LED. They can optionally operate relays and control modules in a

network, as well as releasers on the same panel. This type cannot have a retard time. It

displays **PULL STATION** in the Alarm List.

• Waterflow: This type of input is for water flow detectors. They are required to activate

bells and/or strobes, as well as an LED. They can optionally operate relays and control

modules in a network, as well as releasers on the same panel. This type displays

**WATERFLOW** in the Alarm List. Through programming, Waterflow type alarms can

make the bell circuits they activate to be non-silenceable.

• Supervisory: This type of input is for items such as Shut-Off valves and Pressure sensors

for sprinkler systems. They are required to operate an LED. They cannot operate bells/

strobes but can optionally operate relays and control modules in a network, and releasers

on the same panel.

• Halt: This type of input can only stop the operation of a releaser type output on the same

panel. An LED is required for annunciation of the Halt function. It will use the supervisory

LED. Note: Use of this type of input must be limited access to maintain UL listing.

• Abort: This type of input can only hold the operation of a releaser type output on the same

panel. This Abort function maintains the current state of the releaser. The delay timer will

continue to run until 10 seconds are left. The releaser will resume normal operation as

soon as the input restores. An LED is required for annunciation of the Abort function. It will

use the supervisory LED.

• Monitor: This type of input used to monitor the action of items such as dampers, door,

fans, etc. The supervisory LED is used. Monitor inputs can operate relays and control

modules.
