Tri-Comm Cellular Modem Installation
The GDC with Tri-Comm has the ability to accept commands through the Tri-Comm cellular Modem.
Through a web interface, users can have the ability to operate the stand-alone GDC remotely.
Step 1 – Place the controller's power switch to OFF.
Step 2 – Using the 2nd daughter board socket (Figure 6, G) install the Tri-Comm modem.
Step 3 – Secure the modem onto the cabinet with four retaining screws.
Step 4 – Route the Tri-Comm antenna to the outside of the cabinet. Peel the antenna adhesive and
install on the side of the cabinet.
Step 5 – Place the controller's switch to ON.
When the Tri-Comm Cellular modem is installed in the 2nd output board position, the
maximum number of stations on the 1st output board is increased up to 200 stations.
Lithium Battery Replacement
A 3.9V Lithium battery (P/N 363-2200) is installed in the timing mechanism to sustain the controller's clock time and date for
approximately 10-years with no additional power applied.
WARNING! DANGER OF EXPLOSION IF BATTERY IS INSTALLED INCORRECTLY. REPLACE ONLY WITH THE
SAME OR EQUIVALENT TYPE OF BATTERY. ALWAYS DISPOSE OF USED BATTERIES ACCORDING TO THE
MANUFACTURER'S INSTRUCTIONS.
Step 1 – Place the controller's power switch to OFF.
Step 2 – Remove the ribbon cable from the rear of the timing mechanism.
Step 3 – Remove timing mechanism's circuit board by pushing the retaining clip downward while carefully pulling the PCB
board. See Figure 12.
Step 4 – Secure the Lithium battery into the battery socket. See Figure 13.
Step 5 – Reattach the circuit board to the timing mechanism.
Step 6 – Secure the ribbon cable back to the timing mechanism socket.
Step 8 – Place the controller's switch to ON.
Electromagnetic Compatibility
Domestic: This equipment has been tested and found to comply with the limits for a FCC Class A digital device, pursuant
to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. The equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to the radio
communications. Operation in a residential area is likely to cause harmful interference in which case the user will be required
to correct the interference at his own expense.
International: This is a CISPR 22 Class A product. In a domestic environment, this product may cause radio interference, in
which case the user may be required to take adequate measures.Each stations can activate up to two solenoids.
This product, utilizing a Class 2 transformer tested to UL1585, satisfies the requirements of a Class 2 Power Source as defined
in the NFPA 70 (NEC), Article 725.121(A)(3).
