The MRI-M500S control module can be used to control a supervised output, such as a bell or strobe circuit. The control module monitors the circuit wiring and troubles will be reported. The module will require a separate 24 VDC supply for the controlled circuit. When programming the database in MHI, be sure to program the control module correctly. Choose any “Control ( str )” other than “Control (relay)” for the MRI-M500S module. The MR-2400 will not operate a control module if the supervised circuit is shorted. Also there are options in MHI that affect the MRI-M500S control module but not the MRI-M500R relay module.
The MRI-M500R relay provides two Form C relays. Choose “Control (relay)” for the MRI-M500R module. There are options in MHI that affect the MRI-M500R relay module that do not affect the
MRI-M500S control module.
The MRI-M500X isolator module is used to prevent wiring faults from affecting the entire circuit. It divides the addressable circuit into sections. The isolator has separate IN and OUT wiring. A short on one side of the isolator is not seen on or affects the other side. Isolator modules do not use addresses. The isolator relies on a voltage threshold to determine whether it should be isolating or not. This voltage threshold is around 6.5V. All isolators in a system are in isolated mode on system power up. If there is an excess of current draw, the isolator will not close. When the short is removed, the isolator module automatically closes the circuit again. The LED on the isolator module turns on when the module is in isolated mode, otherwise it flashes periodically. System
Sensor recommends no more than 25 devices between isolator modules since the inrush current of the devices may mimic a short condition preventing the isolator from closing. MRI-3251 detectors have an inrush current of up to 10 times that of other devices, thus only two can be placed between isolators.
The sensors all use bases for mounting. Besides the standard plain bases, there are also relay bases, isolator bases and a sounder base. The available bases are:
MRI-B501
MRI-B501B
MRI-B210LP
Flangeless base for all sensors
Flanged base for MRI-x551 sensors
Flanged base for MRI-x251 sensors, low profile

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 misaddressed. 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-
2200HS-3200 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.
