Duty cycle, not price, is the number that decides whether your barrier survives year two. A buyer's guide to the spec sheet.
Most boom barrier purchases in India are decided on price and arm length. Both are close to irrelevant. The specification that determines whether your barrier is still working in eighteen months is duty cycle — how many open-close operations it is rated for per hour, continuously, without thermal cutout.
Duty cycle is the whole game
A residential society gate might see 400 operations a day. A mall entry lane on a Saturday can see that before lunch. Barriers sold into both situations often carry the same price tag and very different internals. Ask for the rated operations-per-hour figure and compare it against your actual peak, not your daily average — the average is what kills specifications, because the failure happens at peak.
As a rough guide: light-duty units are fine below roughly 300 daily cycles, mid-duty covers most corporate campuses and societies, and high-duty is mandatory for retail and transit lanes. If a vendor cannot tell you the duty cycle, they are reselling something they have not examined.
Safety systems are not optional extras
An arm that descends onto a vehicle is a liability event. Two systems prevent it, and both should be quoted as standard rather than upsold:
- Loop detectors — buried inductive loops that sense a vehicle still under the arm and hold it open.
- Photocells — an infrared beam across the lane that reverses the arm if broken during descent.
- Manual release — a physical override that drops the arm to a free state during a power failure so the lane can be worked by hand.
What happens when the power goes out
In most Indian deployments this is a weekly question, not a hypothetical. A barrier without battery fallback becomes a physical obstruction the moment the supply drops — and a queue forms behind it in under a minute. Battery backup rated for a few hundred operations turns an outage into a non-event. Specify it.
The questions that actually separate vendors
- What is the rated duty cycle, and what is my measured peak?
- Are loop detector and photocell included, or line items?
- How many operations does the battery fallback cover?
- Where are spares held, and what is the committed response time?
- Which controller does it speak to, and is that protocol open?
That last question is the one people forget. A barrier locked to a proprietary controller means the next upgrade is a full replacement rather than an integration.
