Size it before you ask for a quotation.

Two calculators built on the same rules our engineers apply before quoting, with the working shown. Describe the ward or the counter hall; get the model that fits, the models that do not and why, the quantities a quotation should contain — and a link that reopens the exact result.

Each answers one question a buyer actually asks.

Nurse call sizing calculator

“Which Signavanc model fits my building, and how many nurse stations does it take?”

Enter beds, wards, building status and what the ward needs. Get the model that fits with the reasoning shown, every model ruled out with the sentence that removed it, the number of nurse stations, an indicative bill of materials and a Turn Over Time estimate.

You enter
  • Total beds and wards
  • New build, renovation or occupied ward
  • Cat 5/6 pulled or not
  • NABH / JCI response records needed?
  • Mobile alerts and escalation?
You get
  • Recommended model and why
  • Ruled out, and why
  • Nurse stations needed
  • Bill of materials
  • Turn Over Time estimate

Banks, OPDs, service counters

Queue wait time calculator

“How long are my customers waiting, and would one more counter fix it?”

Enter footfall, minutes per customer and counters open. See the average wait in the peak hour, how many people are in the queue, what each extra counter would do — and the queue management system that fits, with the ruled-out models explained.

You enter
  • Visitors per day or in the busiest hour
  • Minutes per customer
  • Counters open and queues
  • Names on the screen? Forwarding? Reports?
  • Cable possible or finished interiors
You get
  • Average wait, queue, counter load
  • Counter-by-counter table
  • Counters for your target wait
  • Recommended system and why
  • Bill of materials
How they work

Three steps, no black box.

The same pattern in both tools: describe, eliminate and rank, then size. Every rule is written on the tool page itself.

Step 1

Describe the site

A handful of plain questions — beds and wards, or footfall and counters. No account, no email wall. The result updates as you type.

Step 2

Eliminate, then rank

Hard rules first: any model that cannot meet a requirement you set is ruled out and told you why. The survivors are ranked for your situation.

Step 3

Size it and share it

Stations or counters, a bill of materials, the maths written out — and every input encoded in the link so the result can be pasted into a procurement note or sent to an engineer.

Who they are for

A number you can take into the next meeting.

Hospital administrators and biomedical heads

Size a ward before the vendor meeting, check a quotation line by line, and see in one sentence why a cheaper model cannot produce the NABH response records you will be asked for.

Bank branch and regional managers

Turn a complaint about long queues into a number — the wait at today's counters and what a seventh counter does to it — and take that table to the regional office instead of an opinion.

Consultants, integrators and channel partners

Size a client's requirement in a meeting, share the link, and let the client reopen the exact configuration. Every rule is published, so the recommendation can be checked by hand.

With every result

What comes back, every time.

Nothing gated

The numbers are free. Only the emailed report asks for contact details.

Ruled out, and why

Each eliminated model with the one sentence that removed it — the part most useful when two quotations look identical.

Bill of materials

Units, indicators, pull-cords, stations, hubs, printers, displays — the counts a quotation should contain.

A link that reopens the result

Every input lives in the page address. Copy it, paste it, send it; it opens exactly where you left it.

An emailed report

The recommendation, the ruled-out list, the materials and the assumptions, formatted for a file — and a Save-as-PDF once it has been sent.

An engineer who sees the same thing

Send the link and we read your configuration, confirm it against your floor plan and book a site survey.

Why trust the numbers

Published limits, textbook maths, stated limitations.

A sizing tool is only useful if a procurement team can check it. Both of ours are built so that they can: nothing in them is a weighting you cannot see, and nothing comes from a datasheet you cannot open.

The limits come from the model pages

LR carries 256 units a station, Air 30 on its own network, Ultra 56, Lite 26; LED Wired shows 8 lines, LED Wireless 5, both to 9 counters and 6 queues. Every number the tools use is published on the product page it belongs to, and nowhere else.

The maths is written out

Turn Over Time and queue waiting time both use the M/M/c queueing model with Erlang C — the formula telephone exchanges and call centres are dimensioned with. It is on each tool page, with the assumptions and their defaults, so any figure can be checked by hand.

The limitations are stated

A calculator cannot see your walls or the bus-load that arrives at ten past ten. Each tool says plainly what it assumes and what a site survey or your own token data will replace.

Built by the people who answer the service calls

We have manufactured these systems in Bengaluru since 2001 and installed them in more than 5,500 sites. The rules in the tools are the rules our engineers apply before quoting.

Frequently asked

About the tools.

Are the tools really free?+

Yes. Every result — the model, the station or counter count, the ruled-out list, the bill of materials and the wait or Turn Over Time figure — is shown without a sign-up. The only thing that asks for your details is the optional emailed report, which goes to you and to our sales team so an engineer can pick the conversation up.

Is the result a quotation?+

No. It is a sizing aid: the model that fits your constraints and the quantities a quotation should contain. Pricing depends on counts confirmed at a site survey — and for a wireless system on a radio-path check through your actual walls — so the next step after the tool is sending us the link.

How accurate are the numbers?+

The model elimination is exact, because it applies published limits. The station and counter counts are arithmetic on the numbers you enter. The waiting-time and Turn Over Time estimates are queueing models with stated, adjustable assumptions — fair averages, not worst cases — and each page says where real data would replace them.

Can I share a result with a colleague or a vendor?+

Yes. Every input is encoded in the page address, so copying the link reopens the identical configuration for anyone. The emailed report carries the same link along with the recommendation, the ruled-out list and the bill of materials.

Do the tools size other manufacturers' systems?+

They size the Signavanc nurse call range and our three queue management models. If you are comparing another supplier, use the station or counter count and the bill of materials as a checklist for their quotation — the counts a ward or a hall needs do not change with the brand on the box.

What if no model fits every requirement I set?+

The tool says so and lists which requirement removed which model, so you can see the trade-off. Relax one — usually cabling status or a feature only one model carries — or send us the link and we will size it by hand.

Need a system sized that is not here yet?

Token displays, GPS clocks, Andon boards and unusual nurse call layouts are sized by hand. Tell us the counters, the hall or the shop floor and an engineer comes back with the configuration — or send the link from either tool and we check the result against your floor plan.
