When using Mercury and NXT Mercury-Powered controllers there are three available default LED modes defined in the software that control how the reader’s LEDs behave when the various modes are set to the readers. Examples of these modes are; Unlocked, Lockdown, Lockout, PIN only, Card + PIN, Access Denied, Access Granted, Locked, etc. By default, all readers connected to Mercury and NXT Mercury-Powered controllers are set to use LED Mode 1 and single-line LED control. You can use the Design Mode feature to edit any one of the default LED modes.
Note: Custom LED modes are only supported on True Mercury and NXT-MSC controllers.
2.0 Default Reader LED Mode (Single-Line)
By default, NXT Reader Interface Modules (RM3 and WI+) are configured for single-line LED mode (D5 LED is solid green and the D1 LED is solid red) and the module is programmed with 03.03.21 firmware. Therefore the Wiegand reader should be wired with a single LED wire that connects to PIN 3 of the reader interface module (there is no wire that connects to pin 4).
Note: a new RM3 module is configured, by default for MS readers (D4 solid red and D2 solid green). To configure the RM3 to Wiegand and single-line LED control please refer to the RM3 installation guide.
For most Wiegand readers (such as Farpointe readers and keypads) when using the default LED mode will provide the following LED behaviour:
- Locked, Card And PIN, Card Or PIN or PIN Only - Solid amber LED.
- Unlocked or access granted - Solid green LED.
- Door forced or held - Flashing red LED.
- Access denied - momentary red LED.
Custom LED modes can be used if you wish for the reader LED to behave differently from the default behaviour. For example; when the reader/keypad is in Card And PIN mode you may wish for the LED to be flashing green or to be alternating between green and red. Custom LD modes should also be used when installing and using OSDP readers.
3.0 Setup Custom LED Modes in Design Mode
- Login to the software and click the Design Mode icon .
- Click Setup >> Hardware Setup.
- Double-click an NXT-MSC controller in the hardware tree.
- You will see LED Modes node located directly beneath it.
- Highlight LED Modes and from the ribbon bar click Add LED icon.
- An Undefined LED Mode entry will appear in the hardware tree.
- Highlight the new LED Mode and the properties will appear on the right.
- From the properties, select one of the default LED Modes (i.e Mode 1). LED is the best mode to edit because by default all readers on the system are assigned this mode. plus it contains all the most commonly used LED behavior for events such as: Access Granted, Access Denied, Door Forced, RTE, Lockout etc.
- From the Reader Function, select a specific reader mode (such as Card + PIN).
- Set the On Color, On Time and Off Color options and decide how you wish the LED to behave during Card + PIN mode.
- The following settings will result in the reader LED alternately flashing between red and green when in Card + PIN mode.
- Save these settings, then highlight a reader in the hardware tree.
- Verify that the reader is set to the default LED Mode of 'Mode 1' - You will need to be in Advanced View to see this setting.
- Click the Design Mode icon again to exit Design Mode and return to the standard mode.
