I'm having trouble setting up WiFi on the Latch R

Ensure the device is up-to-date

 

If you're having trouble connecting to the internet

  • Check for firewalls at the install location and if there is one:
    • Whitelist Latch's AWS Broker URL
    • Whitelist Ports
  • Check if the internet is working at the building

 

If you're having trouble connecting to the Local Area Network (LAN)

  • Check the following:
    • WiFi network is 802.11 b/g/n, 2.4Ghz
    • The Latch R is in suitable range of the WiFi hub: Latch R has a maximum WiFi range of 100ft in clear sight 
    • The WiFi network is not operating with WPA2 Enterprise security. The Latch R does not currently support this WiFi security protocol

Elevator Floor Access (EFA) Installation SOP

Overview

EFA allows a credential to be required to reach certain floors, increasing security. 

Requirements

  • Floor Group Table: The Property Manager must work with Latch to set up floor access ahead of installation. Latch will then generate a Floor Group Table to be programmed into the access control panel being used for elevators. This will be displayed in the Manager App after the R is activated.
  • Third party access controller: The panel must be able to receive a 26 bit Wiegand credential. If the property requires scheduling or floors to be unlocked during certain hours, this needs to be supported by the access controller. The installer must be comfortable working with the access controller and it must be on Latch’s approved list. Installers wishing to use access controllers not on this list must give Latch 8 weeks notice prior to installation to test and approve the access controller. The Installer must provide Latch with a panel should Latch not be able to procure one independently. Latch will minimally support installation/configuration of the panel.
  • Internet: Internet must be provided to the Rs. If an R is installed inside a cab, internet must be provided via Ethernet through transceivers with a coax cable running in the traveling cable. 

Wiring requirements

Programming the Latch R 

  • Activating the Latch R
    • During the activation process make sure to select FW Version 3.1x.xx
  • Configuration
    • Internet is mandatory for all EFA installations.
    • Go to the Device Detail page after the activation process.
    • Go to the Settings page.
    • Configure Ethernet or WiFi.
    • Save changes.

Programming the Access Panel

  • Floor Groups that mirror the Latch Cloud must to be created in the panel. Refer to the Floor Lookup Table on the Device Detail page in the Manager App.
  • The Floor Lookup Table contains the following:
    • Floor Group Name: This corresponds with the User Name field in most panels.
    • Facility Code and ID Code: Put together this is the Wiegand code.
    • Floors: The floors that belong to this Floor Group.

Example:

Testing EFA 

  1. Prior to the day of installation, the Property Manager must create an account for each Floor Group, assign each account a different Floor Group, and give access to each of the accounts to the Integrator.
  2. Before presenting a credential, test the elevator by making sure that all of the necessary floors are locked.
  3. Present the credential for the first Floor Group.
    • Confirm that all of the necessary floors are unlocked. 
    • Example: If the first Floor Group has access to floors 2 and 3, verify that floors 2 and 3 are unlocked.
  4. Continue this process for each Floor Group, including the Daily Doorcode Floor Group.
  5. After testing is complete, the Property Manager should delete each of the accounts created for testing. 

Door State Notifications (DSN) Installation SOP

Overview

Door State Notifications will send notifications to subscribed Property Managers for the following Door States:
 •   Door Ajar: The door is held open for an extended period of time.
       ○   Time period configurable between 30, 60, and 90 seconds. 
 •   Door Still Ajar
       ○   Time period configurable between 5, 10, and 15 minutes.
       ○   This notification is repeatedly sent at this interval until the door is closed.
 •   Door Breached: The door is forced open.
       ○   When the door is opened from the outside without a valid credential.
 •   Door Secured: The door is closed after any of the above Door States.

Preparation

  • An Internet connection to the reader is required for Door State Notifications.
  • All egress sensors and door contact sensors need to have dry contact outputs that are compatible with the Latch R.
  • DSN can only be configured after the Activation process is complete. It is not part of the Activation flow.

Forced Entry alerts sensor requirements: Egress sensor and door contact
Door Ajar alerts only sensor requirements: Door contact

Termination:

Refer to the installation guide for termination requirements. 

Note:

  • When IO1 is configured to ‘Unlock + Egress Sensor,’ an egress sensor/REX that is connected to IO1 will unlock the door in addition to feeding a signal to the Door State Notifications feature.
  • When IO2 is configured to ‘Egress Sensor,’ an egress sensor/REX that is connected to IO2 will NOT unlock the door. It will only feed a signal to the Door State Notifications feature.
  • All devices that can unlock the door from the exterior, such as an intercom, must also be wired into the Latch R and that IO must be configured to “Unlock”. Otherwise, when the door is unlocked by this other device, it will register as a forced entry.
  • Motion detectors must be set to the duration they are expected to leave the door unlocked per motion event, such as 5 seconds or 10 seconds. Otherwise the door may relock prior to a person reaching the door.

Configuring DSN

 1.   In the Latch Manager App, select ‘Settings.’
 2.   Select the appropriate ‘Relay Configuration’ and ‘Relock time’ for this entrance.
 3.   Enable Ethernet. If an internet connection is not available, Door State Notifications must be  disabled after testing.
 4.   If Door Ajar Notifications is desired at this entrance, select Door Ajar Notifications:
       a.   Toggle Door Ajar Notifications to enable.
       b.   Select how long the door must be held open until the Door Ajar Notification is created: 30, 60, or 120 seconds.
       c.   Select how long the door must be held open until the Door Still Ajar Notification is created. This will send repeated notifications at the selected time interval until the door is closed. Choose from 5, 10, or 15 minutes.
 5.   If Forced Entry Notifications is desired at this entrance, toggle it.
       a.   Forced Entry Notifications sends an alert when the door is opened from the outside without a valid credential.
 6.   Configure the IOs for the sensors:
       a.   IO1
             i.   Unlock Only: Only unlocks the door. The signal is not fed into the DSN feature.
             ii.   Unlock + egress sensors: Unlocks the door and tracks egress. Used when egress sensor needs to also unlock the door.
             iii.  Disabled: The R does not respond to any inputs.
             iv.  Select the type of sensor: Normally open or normally closed.
       b.   IO2
             i.    Unlock Only: Only unlocks the door. The signal is not fed into the DSN feature.
             ii.   Egress sensor: Only tracks egress; does not unlock. Used when egress sensor should not unlock the door.
             iii.  Disabled: The R does not respond to any inputs.
             iv.  Select the type of sensor: Normally open or normally closed.
       c.   IO3
             i.    Unlock Only: Only unlocks the door. The signal is not fed into the DSN feature.
             ii.   Door Contact Sensor: Used to determine if the door is open or not. Feeds into the DSN feature.
             iii.  Disabled: The R does not respond to any inputs.
             iv.  Select the type of sensor: Normally open or normally closed.
             v.   Automatic Relock on Door Open: Automatically locks the door when the door is opened, overriding the Relay Relock time when appropriate. 

Testing DSN with Internet

Please refer to Figure 2 for 'Internet Status' and 'Door State.'

 1.   Check that the R has an internet connection. 
       a.   Go to the Lock and check the 'Internet Status.' It must be one of the following: 
Ethernet Connected, WiFi Connected, or Ethernet and WiFi connected.
 2.   Test the Door Contact Sensor. 
       a.   Make sure that the door is closed.
       b.   
Confirm that the Door State says Door Secure.
       c.   
Open the door and hold it for the duration of Door Ajar Timer that was set during configuration.
       d.   
Leave the Device Detail page and enter it again to refresh the Device Status fields. If the Door Contact Sensor is connected and configured properly, Door State will change to Door Ajar.
 3.   
Test the Egress Sensor (if an Egress Sensor is installed).
       a.   
Disable Door Ajar Notifications. Make sure to enable it once the test is complete.
       b.   
Ensure that the Door State is Door Secure.
