Page 3 of 22 AR – 1202RTC ARCHITECTURAL DIMMER Revision 1.93 OWNERS MANUAL 06/03/2008 AR-1202 UNIT DESCRIPTION POWER REQUIREMENTS The AR-1202 consists of an embedded micro processor and 12 dimmer channels of 2.4KW each. Each dimmer channel is protected by a 20 Amp circuit breaker. Heavy duty filtering chokes are used to reduce noise. Dimmer channel semiconductors exceed a 200% load carrying capacity overhead allowance. All components and sub systems are UL recognized components.

REQUIREMENTS The RA-122 can operate as a single phase unit using using only 2 phases of a 3 phase power source. This is NOT RECOMMENDED since it causes an unbalanced load at the power source. The feed circuit must be able to supply 120 Amps for each line.

A DMX console transmits from a female, 5 Pin XLR Connector. Common Shield DMX Data DMX Data + See the EXTERNAL CONNECTIONS and the example below for specific connection information.
Page 8 of 22 AR – 1202RTC ARCHITECTURAL DIMMER Revision 1.93 OWNERS MANUAL 06/03/2008 SMART REMOTE CONNECTIONS There are two types of smart remotes (push button and fader) which can be used with the AR-1202. There are multiple models of each type. They all connect to a common RS-485 bus which is controlled by a AR1202. Additional AR-1202 dimmers may also be connected on the same bus. One of them will be set as the master controller by making UNIT ADDRESS ASSIGNMENTS.

This process is done from the AR-1202 front panel using 5 menus described below. SYSTEM SETUP should be done first. It includes: setting the System Mode, System ID, and System Power Setup. DMX I/O SETUP must be performed if the unit will be used with a DMX console.

DIMMER SETUP 06/03/2008 CONSOLE LOCKOUT: You can set any dimmer channel output to ignore DMX signal inputs from a DMX console by assigning it to DMX channel 0. This feature can be used with house lights or other special lighting.
Page 13 of 22 AR – 1202RTC ARCHITECTURAL DIMMER Revision 1.93 OWNERS MANUAL There are three ways to create or set up a scene: 1. Set each channel intensity manually (EDIT SCENE) 2. Copy another existing scene (COPY SCENE). You can then edit the results. 3. Record a snapshot of the current channel intensities (RECORD LIVE NOW) Push MENU (NEXT) to select one of the 3 methods described above. The display will show the corresponding menu. TO CREATE A SCENE MANUALLY Push ENTER when EDIT SCENE is shown.

The procedure is similar to that for other scenes except the blackout fade time is accessed by selecting SCENE 00 from the SCENE SETUP menu. Factory default fade time is 3 seconds. Blackout fade time may be set between 0.5 and 99.5 seconds.
Page 15 of 22 AR – 1202RTC ARCHITECTURAL DIMMER Revision 1.93 OWNERS MANUAL Currently available fader remotes are the AF-2004, AF-3007 and the AF-5013. Fader remotes are scene block addressable so you can select which scenes will be activated it. There are 3 scene blocks available. Each block includes 16 scenes. The first block starts at scene 51. This refers to the lowest numbered fader on the remote. The other faders on that remote will use the next consecutively numbered scenes (52, 53, 54, etc.).

Turning events OFF is used to prevent triggers which may have been forgotten about, incorrectly set, or otherwise unaccounted for. SET DAY MONDAY SETTING THE DAY OF THE WEEK TO CONTROL EVENT TRIGGERING The day of the week MUST BE SET when setting or changing the date.
Page 17 of 22 AR – 1202RTC ARCHITECTURAL DIMMER Revision 1.93 OWNERS MANUAL Programming an event consists of four steps: 1. Select the event you want to set up (1 - 128). 2. Assign a scene (1 - 100) to the event. 3. Select what action is to be performed for that scene (Turn it ON, Turn it OFF, or IGNORE IT). 4. Assign the DATE/ TIME or DAY(S) / TIME for the event to be triggered. E001S000 DATE 06/03/2008 OR E001S000 DAYS The top row shows the event number and scene number you are working on.

If a day shows as a solid block ( ) instead of a character then the event will be skipped (will not trigger on that day). Use the and buttons to select a week day. Then use the and buttons to change between trigger and skip. Push ENTER once a value has been selected.
