Controller Module (CM)
The Controller Module (CM) is a non-intrinsically safe
module that acts like the brain of your console. The CM
handles all of the communication between the modules
and then sends that information to your output devices.
You can use the LCD touch screen LCD or external printer
(depending on model and configuration) as output devices
to communicate with your system. The CM links to the
status lights on the front of the console and the LCD via
flexible cables.
Flexible Cable Connectors
The flexible cables are installed at the factory and is just
long enough to allow the door to fully open. They are
protected from high power wiring by the metal shroud
attached to the CM. The cables should not be deformed,
but should rather be freely folded back into the shroud so
that they do not get pinched when the door is closed. If the
flexible cables do become detached though, they can easily
be reattached.
To reattach the flexible cables to the connectors, identify
the two sides of each end on both cables: there are metal
bands on one side and no metals bands on the other. The
flexible cables connect to the CM by inserting one end of
each cable into the LCD connector with the cables’ metal
bands facing to the left so that a metal to metal connection
is made with the LCD’s connector pins.
After the flexible cables have been correctly inserted all the
way into each of the LCD connectors there will be no metal
showing above the connection. Once the flexible cable
connector is properly attached to the CM’s LCD connector,
hook it up to the corresponding connector on the inside of
your console’s door by making the same kind of metal-to-
metal connection that you made while inserting it into the
CM’s faceplate.

Power Supply Module (PS)
The PS is a non-intrinsically safe module that provides
power to the TS-550 evo console from line voltage rated
110 - 240 VAC. The PS is two inches wide, occupies two
slots and is located immediately to the right of the CM. The
PS consists of two AC /DC switching power supplies - one
switching power supply is +5V and the other is +24V.
The PS also has two relay outputs for use with remote
annunciators and two low voltage inputs for emergency
generator applications.
Line Power Wiring
At the electrical power panel, use or install a 20 amp
circuit breaker — this breaker should be dedicated to
only supplying power to the TS-550 evo console. Mark
this circuit “TS-550 evo console [power] - ONLY” on the
circuit label (at the back of the electrical power panel door).
Refer to Figure B-1 and the 110 / 240 VAC Line Power
Wire Connection List that precedes it for line power wiring
information.
Note: Avoid connecting other equipment to this circuit.
If other equipment is connected to this dedicated
circuit, the resulting electrical noise could cause
faulty system operation.
Make sure that the TS-550 evo
console’s power circuit breaker is
turned off during any installation.
Lethal voltages are present inside the
console which could kill or injure you.
Also, secure the TS-550 evo console’s
circuit breaker in the off position
and attach a “lockout” to it, which is
dated and signed by you, to prevent
accidental closure, injury or death.
The ground bus in the electrical panel
must be connected to an earth ground
as required by the National Electrical
Code (or Canadian Electrical Code)
when applicable. If the ground bus is
not properly connected to an earth
ground or if the IS safety ground is not
properly connected at the console, a
dangerous condition will be created
which could result in an explosion.
Check Electrical Resistance to Earth Ground
After wiring the IS safety grounds, check the resistance
between the IS safety ground terminals at the console and
the earth ground – this resistance must be less than 1 ohm.
