All Panels - Guide to groups and zones


Any relays that are going to be on a time schedule must be part of a group. When more than 8 relays are being added to a switch button, those relays must also be part of a group. Groups are useful when you have multiple switches that operate the same loads. You can assign a group to a switch or photocell, instead of having to assign every load individually. To create or edit a group, press ENTER on GROUP LOADS on the USER MENU. Select the group number you wish to edit, and press ENTER.  You will a screen similar to this one. 


To add loads to a group, use the same method as adding loads to a Chelsea switch

Group Types

Momentary On

This is similar to On Mode. When a group is set to Momentary On, that group will turn on whenever it is triggered.

Momentary Off

This is similar to Off Mode. When a group is set to Momentary Off, that group will turn off whenever it is triggered.

Momentary Mix

This is similar to Mix Mode. When a group is set to Momentary Mix, the group can trigger some relays ON, and others OFF at the same time.


A group programmed as Maintain will stay on as long as it’s ON command is held. On a switch, the button has to be held down for the load to stay on. This is also the correct group type to use for loads under photocell and time schedule control.

Maintain + Timer

This group type is made to be used in conjunction with time schedules. When a Maintain+Timer group is scheduled on, the auto off timer will be disabled, and the lights will stay on. Outside the hours of its scheduled times, the group will time out and shut off after being on for a certain amount of time.  If you press ENTER while you have this group mode selected, you can adjust the value of the timer by entering into the SET TIMER sub-menu (default is 2 hours).

Maintain + Blink

This group type is the same as a Maintain+Timer group, except the lights will flash before timing out to warn the occupant. If you press ENTER while you have this group mode selected, you can adjust the number of minutes, prior to shutting off, the lights will blink. This setting is also adjusted under the SET TIMER sub-menu. A 2nd blink warning can be programmed here as well.

Overriding Groups

To override a group, select GROUP LOADS from the USER MENU and press ENTER. TAB DOWN and select the group you want to override. SCROLL UP to override the group ON. SCROLL DOWN to override the group OFF.

Deleting Groups

To delete a group, select GROUP LOADS from the USER MENU and press ENTER. TAB DOWN and select the group you want to delete and press the DELETE key. Press ENTER on ‘Yes’ to confirm.

Group Toggle

You cannot toggle a groups do not have a toggle mode. If you want to appear to toggle a group, you have to use 2 groups 1 group set to ON 1 group set to OFF with the same relays in them, a spare status relay, and the button 7 & 8 special functions.

Global Groups

Groups 17-32 are preprogrammed to be global for all multi-bus systems. This means they will activate universally across all system busses whenever activated on any single bus. To take advantage of this feature, the global group must be set up identically on all system busses.



Zones are similar to groups, except a relay may only be assigned to one zone. Zones will only exist if a panel has been set up in zone mode, as opposed to discrete mode. Discrete mode is the normal mode for most systems. In discrete mode, Load 1 is Relay 1; Load 2 is Relay 2, and so forth. In zone mode, Load 1 is Zone 1; Load 2 is Zone 2, and so forth. Zones are programmed using the buttons on the control card. Changing the mode of a panel, from discrete mode to zone mode, is also done using the buttons on the control card.

Changing Panel Mode

To change the mode of the panel, press and hold the ASSIGN button on the control card. After three seconds, the relay LEDs will shut off. Continue to hold the assign button and press the following key sequence on the relay buttons: 

2, 4, 6, 2, 6 

Let go of the ASSIGN button. After about 5 the relays will change state. The panel has now cycled to the next mode. It cycles through the modes in this order:


-8 Zone Mode (Panel uses 8 zoned loads)

-16 Zone Mode (Panel uses 16 zoned loads)

-Discrete Mode (Panel uses a load for each relay)


…and then repeats


Adding or removing relays from a zone

To add or remove a relay from a zone, press the ASSIGN button, and then press the button for the zone number that you’d like to add or remove relays from. Pilot lights for all relays in that zone will light. Press the button for each relay number you’d like to add to, or remove from that zone. If the pilot light for that relay number flashes after you press it, it means that relay is already in a zone. Press the button again to force it into the zone. Leave it alone for 5 seconds, and the relay will not be assigned. Press the ASSIGN button again when you have added or removed all necessary relays to save the configuration.
