MR-2100/2200 Programming Manual
6
The sensor LED activates the relay and sounder bases. When this LED stays on for more than 10
seconds, the base activates. This requires that the MR-2200 have the LED mode set to FLASH/
ON. This is done through the LCD Menu by choosing PROGRAM/ADDRESSABLE/LED MODE/
FLASH. The MR-2200 only turns on the LEDs of up to 5 devices per addressable circuit to prevent
excess current flow. While the panel continues to respond to further alarms from the circuit, the
panel does not turn on additional LEDs. The MRI-B501BH sounder base requires a separate 24
VDC supply for operation. If the polarity of this supply is reversed for more than 10 seconds, the
sounder base activates.
Isolator bases function the same as isolator modules. The sensor plugged into the base is
connected to the IN wiring to the base. The isolator is between the sensor and the OUT wiring.
While both sensors and modules have rotary dials that allow for addresses from 00 to 99, modules
add 100 internally to the address programmed, thus using the address range 100 to 199. Since
sensors and modules come from the factory addressed as 00, we do not allow that address to be
used for an installed device. Address 0 is used for indication of wiring faults on the addressable
circuit.
Device Faults
The following troubles (with condition code letter) can be reported by or for addressable devices:
• Missing (M): A device listed in the database is not reporting back when polled by the
panel. For a new installation, this is generally indicative of devices that have been mis-
addressed. This error can also occur if there are any wiring faults.
• Illegal (I): A device is reporting in on an address that the database shows as unused. For
a new installation, this is generally indicative of devices that have been mis-addressed.
For illegal sensors, since there is no programming available, if an alarm condition is
detected, the MR-2200 operates all its bell circuits. In a network system, only the local
panel activates its bells. The MR-2200 always ignores illegal modules.
• Wrong Type (U): This occurs if the device is not the type expected for the address. For
example, the database lists an address to have a ion smoke detector, but a photo smoke
detector has reported for the address. This error is also used if the panel cannot determine
the type of the device. If the device goes into alarm, the panel operates normally.
• Trouble (T): Sensors: The device is defective and needs to be replaced.
Modules: The extended circuit from the module has a wiring fault. Note: Control modules
that supervise their output circuits are not operated if the output circuit is shorted.
• Duplicate (D): This means that two devices are using the same address. The MR-2200
does a check every hour for duplicate devices. If either device goes into alarm, the panel
operates normally. Note: Due to the method used to detect duplicate devices, it is possible
for a single device to appear as duplicate devices. Generally, the device needs to be
replaced.
