Kentec Electronics Ltd XT+ Releasing Control Unit
Product Information
The XT+ Releasing Control Unit is a product manufactured by Kentec Electronics Ltd. It is designed to provide control and monitoring capabilities for fire suppression systems. The unit features various terminals and wiring connections to facilitate the integration of different components.
Key Features
- Addressable modules with DIP switches for easy configuration
- Power supply connections for AC input and field terminations
- Standby batteries for backup power
- Alarm terminals for connecting audible loads
- Extinguishing circuits for controlling releasing agents
- Top and bottom terminals for various control and monitoring functions
- CIE serial communication for data transfer
Product Usage Instructions
- Setting the Module Address: Set the address DIP switches on each module to a unique address between 1 and 15.
- Power Supply: Connect 18 to 14 AWG wiring for all field terminations except the AC input. Connect 14 AWG wiring for line, neutral, and ground terminations of the AC input.
- Standby Batteries: Use two standby batteries wired in series. The batteries should be 12 VDC, valve-regulated lead acid type with a maximum amp hour capacity of 60 AH. Connect the batteries to the unit for standby operation. The battery charge voltage should be 27.6 VDC.
- Alarm Terminals: Use the provided terminals for connecting nonpulsing audible loads. Each terminal provides a regulated 24V DC, with a maximum output of 850 mA. Ensure to use a 10k Ohm resistor for the required end-of-line (EOL) connection.
- Extinguishing Circuits: Connect the Exting. 1 (Main) and Exting. 2 (Reserve) circuits to releasing agent control valves. Each circuit provides regulated 24V DC at a maximum output of 1A. Use an EOL diode for the required end-of-line connection.
- Top Terminals: The top terminals provide various power and control outputs. Refer to the product manual for detailed specifications of each terminal.
- Bottom Terminals: Remove the jumper LK1 from each module, unless it is the last device on the CIE serial bus. The bottom terminals are designed for different control and monitoring functions. Refer to the product manual for detailed specifications of each terminal.
- CIE Serial: Use a two-wire RS485 connection for CIE serial communication. Ensure that the data voltage is 3.3V and current-limited. The communication is supervised and operates in a Class B mode.
WIRE ROUTING
Because the fascia is hinged, route all wiring to the left as shown, so that the fascia can be opened without disconnecting the wiring. Power-limited conductors must be installed using Types FPL, FPLR, FPLP, or equivalent cables. When connecting field wiring, separate high and low voltage wiring in the enclosure with a minimum gap of 0.25”. Do not route low voltage cabling through the same conduit as AC lines. AC power lines should be threaded through a dedicated conduit. Refer to this illustration when connecting any wiring.
SETTING THE MODULE ADDRESS
Set the address DIP switches on each module to a unique address between 1 and 15. 
POWER SUPPLY
