30. F-ALARM
Select the level and control channels triggered by the fire alarm input.
When a contact is sensed on the fire alarm input, the selected control channels are
triggered on to the selected output level from 0% to 100%. The fire alarm input is
merged with the DMX and analog inputs with highest takes precedence (HTP). The
system will stay in fire alarm mode until the contact is removed.
Press EXECUTE to enter the menu and configure the fire alarm input.
L>FL:01*
Displays the output level (L>FL) of 100% and control channel (01*).
L>00:01*
Press MENU (
) to change the output level from 00% to 100% (FL).
L>FL:01*
Press MENU (
) at the same time to toggle the level back to 100% (FL).
L:FL>01*
Press EXECUTE to toggle the pointer (>) and select the control channel(s).
L:FL>24*
Press MENU (
) to select the desired control channel from 01 to 24.
L:FL>24
Press EXECUTE to toggle the flag (*) for each desired control channel.
Press ESCAPE to exit the menu and save the desired settings.
Press RESET to exit the menu without saving.
The menu will automatically timeout after 2 minutes of inactivity and save.
31. WARMING
Turn the “lamp warming” feature on or off.
The unique “lamp warming” feature is activated by a control level above 0% and
lowers the in-rush current to the dimmer (cold lamp filament) by up to 70%. This
results in significantly increased lamp filament life and lower long-term operating costs.
WARMING is set to ON by factory default, but may be turned OFF for some
installation applications. With WARMING set to ON, a maximum delay of 245
milliseconds is introduced to “warm” the lamp when it is turned on. For fast chase
effects the delay may be undesirable, in which case, the “lamp warming” feature can
be turned off. Note that when standby mode is enabled the microcontroller goes to
sleep within 5 seconds of inactivity on the control inputs, and there is delay of 150
milliseconds for the microcontroller to wake up and restart normal run mode. To
ensure virtually instant dimmer control response, set STANDBY to DISABLED and
WARMING to OFF.
Press EXECUTE to enter the menu and configure the lamp warming mode.
DISABLED
This menu is disabled to help prevent inadvertent changes. Proceed to enable.
ENABLED
Press and hold MENU (
) and MENU (
) at the same time for 4-5 seconds.
ON
Press EXECUTE to toggle the lamp warming mode from ON to OFF.
OFF
Press EXECUTE to toggle the lamp warming mode from OFF to ON.
Press ESCAPE or RESET to exit the menu.
Any change in the configuration is automatically saved.
32. Ø-PATCH
Set the zero-cross phase reference for each dimmer control output circuit.
The defaults (DEFAULTS) menu is normally used to configure the phase patch for
JS-ICON
™
Series dimmer racks. This menu provides custom phase patching for non-
standard applications. If a dimmer control output is patched to the incorrect phase
reference, the dimmer will not dim correctly and will go to full output at around 1%
DMX input.
Press EXECUTE to enter the menu and configure the dimmer phase patch.
CH 01 ØA
Displays the dimmer output channel (CH 01) and patched Phase A (ØA).
CH 24 ØA
Press MENU (
) to change the dimmer output channel to patch from 01 to 24.
CH 24 ØB
Press EXECUTE to toggle the patch to Phase B (ØB).
CH 24 ØC
Press EXECUTE to toggle the patch to Phase C (ØC).
Press ESCAPE to exit the menu and save the desired settings.
Press RESET to exit the menu without saving.
The menu will automatically timeout after 2 minutes of inactivity and save.
