Dual-source meter replacement · Delhi NCR
Replacing old Secure LIY or LIT dual-source prepaid meters?
Secure has discontinued its LIY and LIT dual-source meters. Replace only the meters that have failed with Innologix dual-source prepaid meters, which work with the DG setup your society already has: SMPS, injector (through a soft DG signal) or partial DG.
The situation
LIY and LIT meters are discontinued, and replacing them is not a simple swap
Many Delhi NCR societies installed Secure LIY or LIT dual-source prepaid meters years ago. These models are no longer made, so failed meters cannot be replaced like for like.
What societies run into when they move to Secure's newer meters, based on the sites we survey:
- Higher cost per meterThe newer Secure meters are considerably more expensive, which adds up across hundreds of flats.
- Injector systems need rewiringThe newer Secure meters detect grid or DG supply on their own, but this does not work where an injector is installed. Societies with injector-based DG indication have to lay SMPS DG wiring to every meter to use them.
- External contactors for partial DGWhere the society gives only partial DG backup, the newer meters do not handle it on their own, and external contactors have to be added.
- All meters have to go at onceBecause the newer meters cannot work with the injector, and their software cannot manage the older meters, a society cannot replace only its failed meters. Working LIY / LIT meters have to be replaced too.
- Recharge software does not carry overThe token software for the newer Secure meters is not compatible with the older meters, so the society cannot run old and new meters on one system.
Innologix dual-source prepaid metering
Works with the arrangement you already have
One meter platform for every common DG setup, so the replacement fits your building rather than the other way round.
| Your existing setup | Innologix dual-source meter | What it means for you |
|---|---|---|
| Working LIY / LIT meters still in service | Keep them | Replace only failed meters now. Working meters stay on the existing injector until they fail; new meters use the soft DG signal. |
| Injector-based DG indication | Soft DG signal | DG status taken once in the DG / LT room and sent to the meters by software. No DG wiring to every meter; the injector stays for your existing meters. |
| SMPS DG signal | Supported | Your existing SMPS wiring is reused as it is. |
| Partial DG backup (limited load on DG) | Built in | No external contactor per flat for DG load limiting. |
| Full DG backup | Supported | Grid and DG metered and billed at separate rates. |
| Old token / card recharge | Replaced by online recharge | Balances migrated; residents recharge by UPI, card or net banking in the app. |
How replacement works
From site survey to go-live
- Site surveyWe check the DG changeover panel, the type of DG signal (injector or SMPS), the backup arrangement and the meter boxes.
- Proposal & planMeter count, cost per unit and a phased plan: replace failed meters first and keep working LIY / LIT meters in service.
- Data migrationUnits, residents, tariffs and opening balances are set up in SmartCommunity before the changeover.
- Changeover & supportMeters replaced, residents onboarded to the app, then ongoing support and AMC.
What residents and committees get
More than a replacement meter
- Resident app on Android and iPhone: balance, daily grid and DG usage, bills and receipts.
- Online recharge by UPI, cards and net banking, credited automatically.
- Society dashboard with collections, consumption by source and low-balance units.
- Maintenance billing through the same balance, if the society wants it.
- Helpdesk with complaints raised in the app and escalated to our team.

Questions
Frequently asked questions
Our society has old Secure LIY / LIT dual-source meters. Can you replace them?
Yes. The LIY and LIT series are discontinued, and Innologix dual-source prepaid meters are designed to replace them. We survey your site first to confirm the DG signal type, backup arrangement and meter positions, then plan a phased changeover.
Our DG indication works through an injector. How do your meters know when we are on DG?
In injector-based societies we use a soft DG signal: the DG status is taken once, in the DG room or LT room, and sent to the Innologix meters by software. You do not need to lay DG signal wiring to every meter. The society provides a DG signal point and a WiFi connection in the DG or LT room, and your injector stays in place for the existing LIY / LIT meters.
We already have an SMPS DG signal wired to the meters. Does that work too?
Yes. Innologix meters also accept an SMPS DG indication, so societies with existing SMPS wiring can use it as it is.
We give only partial DG backup. Do we need external contactors?
No. Innologix meters handle partial DG backup themselves, limiting the load each flat can draw on DG, so you do not need extra contactors for each unit.
What happens to residents' balances and history from the old system?
We migrate the unit list, residents and opening balances into SmartCommunity before go-live, so residents carry their balance over. Old token-based recharges are replaced by online recharge through the SmartCommunity app and web login.
Do we have to replace all our meters at once, including the working ones?
No. Your injector keeps working for the LIY / LIT meters, while Innologix meters get the DG status from the soft DG signal, so the two run side by side. You can replace only the meters that have failed and keep the working ones in service. Replace the rest as they fail, or tower by tower when the budget allows.
