Inspector Wants "Specifications For The Mag-Lock System", What Would That Be?

I just had an inspector ask me for the "specifications for the mag-lock system". When I asked him what he means by that, he said I should know. Any ideas what exactly he wants?

Thanks


It means he does not have a clue.

Typically they want spec sheets (for everything) and wiring diagrams - how you intend to build it - all of the parts and pieces. If there is a smoke detector required (depends on the jurisdiction) include that too. Don't forget (since you wrote mag-lock) to include the power supply and fire alarm interrupt. Usually that is installed by the fire alarm service company.

He is likely asking for details on the access control system. You may ask him to clarify his question, and make it clear to him whether or not you're even using maglocks.

Remember, the AHJ may be a clown, but they deserve respect and have a thankless job. See: AHJ / Authority Having Jurisdiction Tutorial

Your advice: "You may ask him to clarify his question"

1's feedback: "When I asked him what he means by that, he said I should know."

I don't think that's good advice in general, since the AHJ has already questioned 1's competence. Brian, what can 1 specifically provide to start to build up confidence?

It's more likely the AHJ is embarrassed at how little they understand the system and saving face by being vague than they are questioning the installer's competence.

AHJs more easily understand when potential design elements cross over into their jurisdictions, like if/how the maglocks interface with the fire alarm. This is why it is important to have the AHJ clarify the question. Not wasting the AHJ's time with irrelevant details is a considerate gesture, and pushing back for clarity on the question is not inappropriate.

As far as thawing the ice, starting with whether or not maglocks are being used at all comes first, then providing details on how life/safety codes are met (via Request to Exit design and fire alarm interfaces) is a good place to begin the conversation. Installers well versed in relevant codes can really set themselves apart here (see: The Codes Behind Access Control).

Not to promote any specific manufacturer, but Securitron (part of Assa Abloy) published a document called Code Inspectors Handbook for understanding Electric Locking Hardware a few years back.

I don't know if this has been updated to reflect current codes, but always thought it did a good job of addressing this topic in detail.

Before anything else, I think that Undisclosed 1 needs to tell us what his scope of work is on this project.

If it actually involves any access control design or installation WITHOUT any mag-locks, that's something that needs to be addressed very carefully to avoid any appearance of incompetence. But at least he has the fallback of, "We're not using mag-locks, so that's where the confusion came from."

If, God forbid, it actually involves access control WITH mag-locks, then I would have a partner or whomever has the expertise respond at first, and after demonstrating mastery bring the OP back in.

But, if he is doing video surveillance and nothing to do with Access, then he should go at once to the AHJ and state so. The longer he waits in this case, the worse the impression, and even after it gets clarified, the AHJ may still have some lingering doubts about why the OP didn't just say, "That's not me" right away.

Man I write some stupid stuff sometimes. I'd unhelpful myself if I could. Just ignore.

I think the AHJ has shown some remarkable insight on the issue (assuming he knows what he is talking about). I have seen many installations of mag locks that have not met Code. It is all about the DESIGN of the "system" to include all the components that control the lock. Fire rating of the door also need to be considered. If I were you, I would first review the applicable code (under "Means of Egress: Access Controlled Doors), a drawing of how you intend to wire the lock and all the connections involved; but know that even if you do submit all this, and its approved, and if it's wrong, you are still responsible.
