Operation and Programming Concepts
The sensors all use bases formounting. Besides the standard plain bases, there are also relay
bases, isolator bases and a sounder base. The available bases are:
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.
1.4.2 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
