The TripMaster MOD (Modular) Emergency Power Off Control Center (EPOCC) is designed to handle heavy switching loads with field selectable versatility to provide the best EPO solution for any facility. The EPOCC simplifies designing EPO control systems by providing individual relay outputs for as few as 4 outputs to as many as 20 isolated high current relay outputs different systems in the data center.

The standard design of the TM-MOD eliminates the problems found when using custom designed and site built EPO control systems. The TM-MOD is a perfect control for EPO operations. Three independent EPO inputs allows the customer or engineer to easily choose one input for EDPO buttons, another for fire panel input and still another for a time protected input to prevent accidental shutdown. All EPO inputs can be protected using multiple time delays and each can be field selected for the best protection timing.

The relay output modules provide four Form “C” non-powered relay contacts on each board. Each relay contact is protected with individual MOVs for a lifetime of dependable relay operation. The 10 amp continuous duty contacts can control virtually any emergency shut down duty.   Each relay output is isolated making it easy to mix control voltages without risky onsite wiring kluges. Simple select the number of epo control required and use the number of relay output boards to provide the emergency control. Should the facility grow in the future simply add additional relay output boards.

EPO OPERATION
When a remote EPO switch or fire alarm contact is activated a latching relay senses the signal and locks the selected output relay modules on that EPO channel in the EPO position. Once in an emergency position, the TM-MOD will require a manual reset to return to normal operation. 

Battery Backup
Each TM-MOD is supplied with a DC voltage power supply that provides an input for standard batteries. The TM-MOD also provides charging for the batteries.

The TripMasterMOD control displays the current condition of the EPO control center. Every control switch and display the operator may need is on the TMMOD face. EPO Select Switch - Places the TMMOD in the Armed, Off or Safe Mode. EPO Armed LED - Lights when the TMMOD is armed and ready to shutdown the facility on EPO inputs. Safe Mode LED - Indicates the TMMOD is in a SAFE mode for testing or maintenace. EPO On LEDs - Light when any of the three EPO inputs has activated and latched. EPO Reset Switch - Once and EPO Evebt has latched this switch will reset the TMMOD to normal. EPO Power ON LED - Lights when power is available to the TMMOD. Fuse - Overcurrent and short circuit protection for the TMMOD. The image on the left is our TripMasterMOD-IG Industrial Grade system with 22mm industrial grade switches and LEDs. Our TripMasterMOD-DP uses standard switches and LEDs.

EPO SAFE Mode Key Switch - Using the keylock switch the TMMOD can be placed in the Safe mode. Allowing field wiring, testing or maintenace to be performed wihtout risking an accidental shutdown of the Data Center equipment. An led will light to indicate Inhibit Mode. EPO RESET Switch - Once an EPO event is lathed the EPO ON led will light. To reset the TMXL to normal preset the EPO RESET button.

Time Delay - The TripMasterHD can be equipped with up to three optional adjustable time delays in the EPO latching circuits. Any of the three EPO inputs can be time delayed or used as instantanious. The Time delay (TM-TD) will prevent accidental shunt tripping by delaying the shutdown. This will prevent accidental shut down due to human error when depressing control buttons next to entrance doors. Up to three TM-TDs can be ordered with TtipMaster MODs.

EPOB Relay Modules
The EPOB (EPO Board) provides four 10Amp, MOV protected relay outputs for emergency power off control of CRACs, UPSs, PDUs, Generators, Fire Dampers even emergency lighting. Each EPOB can be field selected to operate on EPO Input 1, 2, 3 or any combination or inputs. The EPOB(s) for the AC units can operate on EPO 1 as a mushroom switch and also with EPO 3 from the Fire Panel. Another appilcation could have Room-A EPO switch shutting down the AC units in that room while the EPO switch in Room-B shuts down the ACs units in that area. With the Fire Panel shutting down all AC units and the UPS and PDU power systems. No factory wiring or additional cost, just use the jumpers provided to select the EPO sequence for your facility.

The Control Board 1 main control board
The CB1 controls the features and function of the TMMOD. All power connections, EPO inputs, Alarm Outputs, EPOB boards, time delays, batteries,leds and switches connect to this board. Deplugable terminal blocks make it easier to field wire. The Safe Mode audible alarm and silence button is also on the CB1.

Optional Internet AD Remote Dialer
The optional (TM-AD) allows the TM-MOD to remotely announce alarms using the Internet to email, cell phones, SMTP or MODBUS.  This option requires an Ethernet connection to the Internet provided by others.  The alarm inputs to the TM-AD are factory pre-wired.  Six total alarm types can be sent to remote cell phones or tablets as text messages. Emails can be sent to remote PCs or direct connection to other facility monitoring or control systems using SNTP or MODBus. TM-AD is field programmed via web browser and the TM-AD stores historical data logging of alarm events. 

The TM-AD optional can be added at the factory on order or as a separate panel to existing field systems.
