The MIX-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 MPI, be sure to program the control module correctly. Choose any "Control (str)" other
than "Control (relay)" for the MIX-M500S module. Also there are options in MPI that affect the
MIX-M500S control module but not the MIX-M500R relay module.
The MIX-M500R relay provides two Form C relays. Choose "Control (relay)" for the MIX-M500R
module. There are options in MPI that affect the MIX-M500R relay module that do not affect the
MIX-M500S control module.
The MIX-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. 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:
MIX-B501 Flangeless base for all sensors
MIX-B210LP Flanged base for MIX-x251 sensors, low profile
MIX-B501BH Sounder base for all sensors
MIX-B224BI Isolator base for MIX-x251 sensors, low profile
MIX-B224RB Relay base for MIX-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 FX-2200 have the LED mode set to FLASH/
ON. This is done through the LCD Menu by choosing PROGRAM/ADDRESSABLE/LED MODE/
FLASH. The FX-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 MIX-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.
