Openpath

From Asmbly Wiki

Asmbly uses Openpath smart readers for building access control (door locks). This system uses a smartphone app as a primary authentication mechanism, so you don't need to use a key fob or badge anymore.

To set up an Openpath credential on your smartphone, click on the link in the Openpath invitation email. If you haven't received an invitation, you can install the app but can't set up access to Asmbly.

For Users

Subscriber access is granted on successful completion of all pre-requisites for membership:

The Openpath invitation email is sent by setup@openpath.com and has the subject line "Time to set up Openpath for Asmbly Makerspace!". If you expected an invitation and did not receive one, check your spam folder.

As of now (Feb 2022) Openpath invites are sent automatically every morning prior to the shop opening. If you've completed all your pre-requisites and need urgent activation, email ops@asmbly.org for assistance.

If your subscription lapses in Neon, your Openpath access will be suspended. It will be re-enabled when you renew. Email notifications for access suspension and resumption are sent by notification@asmbly.org with subject lines "Your Asmbly Facility Access is Disabled" and "Your Asmbly Facility Access is Enabled", respectively.

For Administrators

Board members and some stewards have access to Asmbly's management interface at https://control.openpath.com.

Keyfobs

Keyfob orders are fulfilled from the scanned keyfobs assigned to the Openpath user "Unregistered Keyfob". Find the Weigand credential that matches the fob you're sending. Copy the card number to clipboard/notepad and delete the UK's corresponding credential. Find the purchaser in Openpath and create a new Weigand credential for that user. Paste the card number into the new credential. Confirm the parsed "Card ID" matches the label on the keyfob. Save the credential.

When you mail or hand-off the keyfob to the purchaser, mark the Neon order fulfilled.

If "Unregistered Keyfob" is all out of credentials, grab another handful from stock and scan them in turn at any OP reader. You can find the card numbers in the access log.

About the Hardware

Our panel has a dual-voltage accessory power supply, which takes up a fair amount of space and we don't actually need since all our lock hardware is 24V. We could fit bigger backup batteries if we removed the 12V supply parts. On the other hand, the dual-voltage power supply includes individual fuses for each door lock, which may be prudent to retain.

Smart readers are connected to the panel via shielded CAT6. The install manual didn't specify a color code, so here's what we used:

Color Signal
Brown / Brown-White Ground
Orange / Orange-white +V
Blue Data+
Blue-white Data-
Green / Green-White Door position contact (NC)

Two conductors are used for power and ground to reduce voltage drop. Our runs may be short enough that this isn't strictly necessary, but I have not confirmed. The door lock hardware itself is actuated by a separate single-pair security cable.

We have not yet set up end-of-line supervision for door contacts for open/short detection. It would perhaps be prudent to do so.

All the hardware manuals have been scanned and saved in Google Drive.
