SW2 DIP Switch Settings
SW2 switch settings are as follows:
1 - ON = Key-switch Enable, OFF = Key-switch Disable.
Switch 1 set to the ON position enables the key-switch operation. The key-
switch may now be used to enable LED-10N membrane (control) switches,
allowing remote switch functions, or lockout the switches, preventing remote
switch functions. Switch 1 set to the OFF position disables the key-switch
operation. Refer to Operation Section for key-switch function description.
2 - ON = Piezo sounder enabled, OFF = Piezo sounder disabled.
CAUTION: Piezo sounder must not be disabled without prior approval of the
Local Authority Having Jurisdiction.
UP POSITION = OFF
DOWN POSITION = ON
LED-10N Addressing
SW1 DIP switches 1 through 6 are used for addressing the LED-10N.
Each device
connected to the EIA-485 communication bus must have a unique address. This allows
specific data to be transmitted between the FACP and that device and for individual
supervision of each LED-10N annunciator by the FACP. Switch settings and the
corresponding addresses are shown in Table 1-1. (Address '00' is invalid).
Note: 1 = Switch in the UP (OPEN) position.
0 = Switch in the DOWN position.
