Detex SW2B – Frequently Asked Questions

1) What is the difference between the Detex S2B and the HS2B?
Alert type is the only choice you make here. The S2B is strobe only, a visual alert. The HS2B adds a horn to the strobe, so you get audible plus visual. If the unit is going somewhere with machine noise, forklifts, or music playing, the horn/strobe is the one that gets noticed; if it is going in a quiet area, a library, a hospital corridor, or a space where a horn would be disruptive, the strobe-only version does the job without the noise complaint.
2) Is the Detex S2B strobe an alarm on its own, or does it need something else?
It is an auxiliary alert, not a standalone alarm. The S2B and HS2B are remote annunciators that are wired to and driven by a security or exit alarm system, so you need that host device in place. Think of it as adding a second, louder or more visible point of notification away from the door itself, at a guard desk, down a corridor, or on the outside of a building where the door alarm cannot be seen or heard.
3) Do I have to drill the backbox to run conduit into a Detex S2B?
No field drilling. The backbox is supplied with knock-outs, so you punch the one you need for your conduit or cable entry and mount it. The box also runs deep enough to keep conductors from getting pinched behind the plate when you fold the wiring back in, which is where these units usually get damaged on install.
4) Can I test the wiring on a Detex S2B before I mount the head on it?
Yes, and that is the point of the mounting plate shorting spring. Land your conductors on the plate and the spring closes the circuit, so you can verify the run and confirm the host system sees it before the strobe or horn/strobe assembly is plugged on. On a long conduit pull or a retrofit through an existing raceway, that saves pulling the unit back apart to chase a bad splice.
5) How does the Detex S2B mount, and can one person swap the head out later?
It is a plug-in design: the mounting plate and backbox get wired and secured, then the alert head plugs onto the plate. Service is the same in reverse, so a failed strobe comes off without disturbing the field wiring or the conduit connection. For a facilities crew standardizing across several doors, that means a replacement is a plug swap rather than a re-termination.
6) Can I add a horn to a Detex S2B strobe later, or do I have to pick now?
Pick at the order. Strobe-only and horn/strobe are two separate configurations of the unit rather than a horn accessory you bolt on afterward, so decide up front whether the location needs audible notification. If you are covering a mix of areas in one building, order the horn/strobe for the noisy or unattended spots and the strobe-only for the quiet ones.
7) What do I need to confirm before wiring a Detex S2B into an existing panel?
Check that your power supply matches the unit's electrical requirements and has the current capacity to carry it, since a strobe and horn draw more than a contact device and an already-loaded supply is the usual failure. Kill power before you open anything, use wire gauge and connectors suited to the run, and pull the manufacturer's installation instructions for the wiring diagram before terminating.
8) Is the Detex S2B rated for commercial use or is it a residential device?
Commercial. The S2B and HS2B are built for commercial security applications: retail loss prevention, healthcare and school facilities, warehouses and distribution centers, and industrial monitoring. A property manager putting one on a multi-family building is within the intended use; it is not a consumer doorbell-grade product.
9) Will a strobe be visible in a bright warehouse or a sunlit entry?
The strobe on the S2B and HS2B is high-intensity and intended to stay readable in bright ambient light, which is why it gets specified for loading docks, glass-front entries, and open warehouse floors where a small indicator lamp disappears. In those same spaces the horn/strobe version is usually the better call, since ambient noise is the other thing working against you there.
