FAQ
Straight answers for techs and buyers evaluating an early commercial RTU.
What is WardenRTU?
A compact remote terminal unit for communications and critical-infrastructure sites. It monitors dry contacts, drives relays, exposes SNMP (poll and traps), can email on alarm, and provides a local web Status UI — without requiring a cloud service.
Who is it for?
Commercial radio techs, county/state communications, small-to-mid telecom, WISPs, microwave shelters, and utility/facility sites that need dependable contact monitoring into an existing NMS — and cannot justify multi-thousand-dollar enterprise controllers on every site.
How much does it cost?
The WRTU-3B is $449, including standard US shipping. Buy online, or use the contact form if your agency needs a PO, a quote, or a pilot conversation first. Sales tax is added where required. Built to order: ships in about 2–3 weeks; larger orders about 4 weeks. We email you a ship date. Add-ons such as PoE power, site-DC power, or plant-isolation hardware are available on request.
What is included in a pilot?
A working unit, guidance to commission Status / sensors / SNMP or email into your environment, and a clear go / no-go after you have exercised real points. Use the pilot request form so we know site type, NMS, and I/O needs up front.
Does it work with InterMapper?
Yes. WardenRTU is SNMP-native with a custom MIB and supporting assets aimed at InterMapper workflows (poll and traps). Other managers (LibreNMS, SolarWinds, generic SNMPv2c) use the same SNMP poll and trap model.
Is a cloud account required?
No. Core monitoring and the UI run on the unit on your management network.
How is it powered? Is PoE included?
The base unit is intended for conventional DC / local supply. PoE is an optional add-on when one-cable power+Ethernet is worth the extra cost for that site. Say which you prefer on the pilot form.
Can I wire 12 V / 24 V / 48 V plant directly?
No — not to bare logic-level inputs. Dry contacts at logic level are for properly isolated or dry-contact sources. Plant voltage loops need isolation hardware. If your site has wet plant loops, tell us on the pilot request; we will not encourage unsafe wiring.
Is this a full SiteBoss-class site controller?
No, and it is not trying to be. Enterprise controllers earn their keep when you need deep automation, large I/O matrices, access platforms, and accessory ecosystems. Warden is for the large middle: door / power / gen / radio contacts, local Status, and SNMP into tools you already own.
What about outdoor / NEMA / UL ratings?
Treat Warden as a management-network appliance for cabinet/shelter install. Do not assume outdoor NEMA or safety listings unless a specific SKU documentation says so. Enclose and protect the unit as you would other non-outdoor-rated electronics at that site.
How do software updates work?
Package install from the UI with health check. If a package fails checks, previous software can roll back. Config on the unit is intended to survive normal update paths.
What support do I get?
Direct email support at info@WardenRTU.com, help commissioning your first site, and software updates as they become available. Each unit carries a limited 90-day warranty against defects; see the Terms of sale.
How do I buy more than one?
Order any quantity at $449 each, US shipping included, using the buy option on the contact form. For larger orders, a purchase order, or a formal quote, choose the pilot / talk to us option. There is no dealer program yet; integrators wanting multiple sites can say so on the form.
Is the software open source?
The commercial product is the supported appliance experience (UI, packaging, and hardware path). Licensing and distribution details are confirmed at sale / pilot — do not assume unlimited free redistribution of the commercial stack.
