All inputs and outputs are independently programmable through the Option-X Access Control Software. 5. Follow the 9-pin RS232 communication cable back to the blue connector to which it is connected on the Option-4 board.
- Page 5 Entry-Master Option-4 Hardware Installation Guide B. Power Instructions 1. The Option-4 board can be powered by AC or DC, from 12V up to 24V input. However, the Option-4 board only provides a maximum of 12V DC on any of its outputs, and 5V for iButton reader power.
- Page 6 Entry-Master Option-4 Hardware Installation Guide 6. Please Note: When using 16 to 24 volts AC to power the Option-4 circuit board, the heat sink on the 12V regulator will get quite hot. This is normal and is not a cause for concern.
- Page 7 ! Dip Switch 5 comes from the factory in the OFF position ! Switches 6, 7 & 8 all come from the factory in the ON position 6. The Option-4 board supports only the Dallas iButton readers. Only two of the wire leads are used for each reader. The wiring...
- Page 8 (approximately 350 feet) from the Option-4 board. D. Connecting the Inputs 1. The Option-4 circuit board has two (2) connectors for Inputs; inputs are used to monitor doors that may have been propped open, opened without a card, or simply as a Request to Exit, also known as a REX button or switch, which allows a person to unlock a door from somewhere other than at the door (i.e.
- Page 9 Reader 2. E. Connecting the Outputs 1. The Option-4 circuit board has four (4) connectors for Outputs; outputs are used to control the lock status of doors. The outputs can also be used to lock and unlock doors on a scheduled basis (See the Option-X Software Manual for more detail on this).

If an Option-4 board is not powered through a UPS, a battery backup is recommended. 5. Wiring from the iButton readers to the Option-4 board should be done with non-shielded cable.
- Page 14 The "collector" is the middle pin of the 3-pin connector for either transistor output on an Option-4 board. There are three (3) ways of utilizing the transistor output: in the first method, the Option-4 board actually powers the locking mechanism, providing voltage to the lock coil.
- Page 15 The installation of diodes is necessary and extremely important!!! Failure to follow these instructions may damage the Option-4 board!!! The third method involves the use of an isolation relay, powered directly by the transistor. The advantages of this method are: (1) the use of AC locking mechanisms (the first two methods can operate only with DC power);...
- Page 16 Fail-safe and fail-secure functionality is accomplished through DIP switches 3 and 4 on the Option-4 board. See the EMRI-2 Board Installation Guide for further details. Always check polarities, current draw and measure voltages before connecting devices to a transistor output.
