Zeta’s Infinity ID2 panels now ship with new firmware (Panel: 1.U / Loop: 0.P) and three changes installers have asked for: access codes you can change, a double-knock mode for input/output (I/O) modules, and a walk test that covers every zone in one pass.
None of these changes alters how you wire or address an ID2 system. They make the panel quicker to commission, easier to hand over securely, and more flexible where a site needs confirmation before an output operates.
Here’s what has changed and what it means on your next install.
Change the panel access codes to suit each site
You can now set your own codes for all three access levels:
- User access: for the responsible person’s day-to-day controls.
- Engineer access: for configuration and commissioning.
- Test/Disablement access: for putting zones into test or disabling parts of the system.
Each code can be up to four digits long. That means you can keep engineer access with your company and give the client a user code of their own. Codes can also be changed when staff leave or a maintenance contract changes hands.
At handover, record the new codes in the site’s system documentation and make sure the responsible person knows who holds them. A recovery procedure is available if a code is lost or unknown.
Hold the relay until a second smoke detector confirms
The new SM-2 operating mode lets an ID2 I/O module wait until any two smoke detectors on the panel have activated before its relay operates. The detectors can be in different zones. This mode applies to the ZAIO-MI and ZAIO/230 modules.
That distinction can matter when a relay controls something disruptive, such as plant shutdown, door release or a signal to another system. Here’s how SM-2 responds to different triggers:
| Trigger | What the SM-2 relay does |
|---|---|
| One smoke detector activates | Waits. The panel goes into alarm as usual, but the relay does not activate. |
| A second smoke detector anywhere on the panel activates | Activates. |
| A manual call point is operated | Activates immediately. |
| A heat detector activates | Activates immediately. |
SM-2 affects the I/O module’s relay only. One smoke detector still puts the panel into alarm and operates the sounders as usual. It is the selected relay that waits for a second smoke detector.
As with any coincidence arrangement, agree the proposed operation with the system designer and the person responsible for the fire risk assessment before enabling it. Record the arrangement in the cause-and-effect documentation.
Walk test the whole system in one pass
The ID2 already offered a one-person walk test. Previously, you could place only one zone into test at a time. With the new firmware, you can put all zones into test together.
On an eight-zone panel, that could remove repeated trips back to the panel as you move through the building. You can follow a sensible route and test devices in the order you reach them.
Remember that zones in test are not providing normal protection. Tell the responsible person before testing begins, and confirm the panel has returned to its normal state before leaving site.
Getting the new firmware
Every Infinity ID2 panel Huvo now supplies has firmware Panel: 1.U / Loop: 0.P installed, so there’s nothing extra to order. At present, the firmware is available in new panels only.
