APPLICATIONS
Each TC-2 provides two releasing device circuits or three
indicating circuits. The TC-2 may be expanded with ONE
of the following:
a) Use the ICE-4 to provide four additional Style Y (Class
B) or Style Z (Class A) supervised notification circuits
or releasing circuits.

CONSTRUCTION
EVACUATION OPTIONS
The TC-2 consists of a panel-mounted printed circuit card with removable
terminal blocks for connection of field wiring.
1) PRE-SIGNAL EVACUATION.
INSTALLATION
The TC-2 mounts in one module position using two captive screws. The ribbon
cable connects the TC-2 to the CPU-500. An auxiliary power harness is
provided with each TC-2 for connection to the MPS-24BPCA or an optional
APS-6R power supply.
RELEASE OPTIONS
1) STANDARD RELEASE.
Two “Enable” points are provided on the TC-2, each of which may be mapped
by the CPU-500 to be activated by one or more IZ-4 or IZ-8 circuits. Activation
of either enable will illuminate its green LED on the TC-2. If a single-zone-inalarm warning circuit is needed, one of the CPU-500 indicating circuits may be
used.
Similar function to Triple Coded Release above, except the “release”
circuits are used for evacuation audible/visual devices. The time period
during which only the single warning bell sounds, is used to provide an
investigation time to verify the alarm before evacuation. Usually, alarms
are mapped into both enables (cross-zone not used). The differences
are:
• The warning circuit pulses at 20 PPM while the timer is running and
steady after time-out. The general evacuate circuits are off unless both
enables are activated.
• The Alert Hold input may be used to freeze the timer (similar to abort).
• It is possible to program up to 7 minutes and 30 seconds of time with
this option.
2) DUAL-CODE EVACUATION.
A programmable, internal, timer (5-60 seconds) is activated when both enable
commands are received (cross-zone). Four green LEDs flash to indicate time
remaining until release. This indication is in binary, with the last 5 seconds at
double flash rate. The warning circuit activates steadily from the start of the
timer. If either enable command is reset, the timer is automatically stopped, and
the indicating circuit is turned off.
Same function as Pre-signal Evacuation above, except all indicating
circuits (3 on TC-2 plus 4 on optional ICE-4) activate slow or march time
when the timer is running and fast march time after time-out. (Slow
march time indicates alert and fast march time indicates evacuate). 20/
120 ppm.
A supervised, external, abort circuit may be activated (shorted) to freeze the
above timer or prevent its start. Abort will only freeze the halon release timer
when it has reached the last 5 seconds. Return-to-normal of the abort circuit
resumes the timer function (non-latching or “deadman" abort function). An abort
command from CPU may also be programmed as a mapped point (latching
until reset). An abort green LED flashes to indicate abort from the supervised
circuit and illuminates steady for CPU-commanded abort. While the timer is
frozen, the warning circuit will remain on.
FRONT PANEL
CONTROLS/INDICATORS
At time-out, two release circuits are activated. If an ICE-4 or CRE-4 is installed, the additional outputs are also activated for a total of 6 release circuits.
A release green LED flashes at double rate. The indicating circuit rings steadily.
The control panel must be reset to turn off the release circuits. Each release
circuit is intended for use with a single, supervised solenoid. Therefore, a short
circuit condition on these circuits is reported as normal by the TC-2.
A manual release command from the CPU is provided which may be mapped
from any IZ circuit. When this command is received, it overrides the enable and
abort commands, and starts the release timer with seconds remaining. The
release LED turns on and remains steady for the 5 second period, then pulses
at double rate after time-out. The warning circuit turns on and remains steady
from the start of the 5 second period. If the manual release command is reset
during the 5 second period, the timer, LEDs, and the warning circuit return to
their previous state.
2) TRIPLE CODED RELEASE.
Same as Standard Release except warning circuit is activated as follows:
•
•
•
•
20 PPM if only one enable is received and the timer is not running.
110 PPM if the timer is running.
20 PPM if the timer is frozen.
Steady-on after time-out and release occur.
3) IRI RELEASE.
Same function as Triple Coded Release, except abort is ignored once both
enables are activated and the timer has started. Abort may prevent timer start
and release only if it is activated before the second enable is received. In
addition, the warning circuit will pulse at 20 PPM with only one enable, if that
enable is Enable 1.

SPECIFICATIONS
• Maximum current per circuit is 3.0 amps. See note 1.
• End of line device is a 4.7 K ohm, 1/2 watt resistor, for Style Y
configuration.
• Standby current consumption: 0.072 amps.
Note 1: Each TC-2 may be powered from two separate
power supplies (providing JP1 is cut). Use one
MPS-24BPCA plus one APS-6R to provide a total
system alarm current of 8.0 amps with a maximum
current per circuit of 3.0 amps. Release circuits
must use filtered 24-volt power. MPS-24BPCA
provides 2.0 amps of filtered power while
APS-6R provides two additional filtered 3.0
amp outlets.
