Installation instructions
The removable cylinder is encased in a zinc alloy housing with a brushed steel finish. Various parts are included in the package to position and secure the lock to the glass door. The door can be from 8 to 15mm thick and may be left or right hung. A useful YouTube video is available to run through the details.
Removing the back plate of the assembly that is held in place by 4 x M4 cross-head screws gives access to the two battery holders. These hold the 4 x LR1 size N, 1.5v batteries that are series connected. Once fitted the unit is ready for fitting to the door and programming.
The external handle freely moves when the lock is not activated. Entering a valid 4-digit key code or presenting a programmed card triggers an internal clutch that engages with the latch actuator and allows the door to be opened. The keypad emits a blue flash and double beep for a valid entry or a red flash and longer beep for an invalid entry or card presentation.
The lock is supplied with two override keys that can be used to open the lock at any time. These can be supplied “keyed alike” if required.
The lock is quickly programmed using the numeric keypad and a range of simple commands.
The keypad has 12 buttons consisting of the usual 0 to 9 telephone format layout, with * and # keys completing the set. The * key is reserved for certain programmes and when using NetCodes and the # key is used for programming the device.
An initial 8-digit factory-set master code is used to access the device, and this must be changed after installation.
The major programmable options are selected by pressing the # key followed by the master code and then the program number; in between each section entered, the keypad will flash blue once (·) to confirm input and twice (··) at completion. A red flash indicates incorrect entry. The available options include:
01 · to 03 ·· - to change the Master and Sub-Master codes, and delete the Sub-Master.
04 ·· - Code Free mode setting. 05·01· to 05·04· suspend or restore individual or all, code-free periods.
06 · - change the re-lock delay time. Enter a time from 02 to 30 seconds (default is 5 seconds).
07 ·· - Emergency Open cancellation.
08 · 01 ·· to 08 · 02 ·· - disable / enable the locked status indicator. The red LED will flash every 5 seconds (reduces battery life).
10 · to 12 · - update the Time & Date, DST months and DST hour on the lock.
13 ·· - feature restrictions. Follow with a zero or 1 for User codes, Smart Cards and NetCodes respectively.
14 · 0 ·· to 14 · 2 ·· - disable / timed / enable keypad illumination. Off by default, amber backlight when buttons pressed.
15 · 1 ·· to 15 · 2 ·· - Lock-Down / Cancel. Only the Master and Sub-master codes can unlock the door.
20 · 1 · to 20 · 4 · - Add code or Card Client. Enter code or present card as appropriate.
21 · and 22 · - Suspend / Restore a Code client.
25 · and 26 · - delete a single / all Code client(s).
27 · and 28 · - Set / Suspend / Restore Active Periods for specific or all clients.
29 · 1 · to 29 · 2 · - enable / disable selected day lock out.
52 · - Block a specific NetCode®.
60 · - Enable a Guest Code
It is important to ensure you enter two-digit codes where necessary such as for the lock delay time, but any incorrect entry will be clearly identified by a red led flash. The programming and operating instructions give clear examples of each code entry.
More flexible programming is enabled using the K3 Connect app that can be downloaded for iOS and Android devices from the relevant app stores.
Downloading and using the app requires registration and acceptance of the associated Privacy and Terms of Service agreements. These include references to the fact that your personal information may be transmitted and stored in territories other than where you are located or potentially in other jurisdictions where there is no privacy protection available. These are referenced to Taiwanese law. As with all such software a cautious approach to allowing access is advisable.
When synchronising the lock with the K3 Connect app, the lock will capture the time from the managing mobile device.
In addition to lock management, the app can be used to e-mail access permissions to other users of the app. These can be very closely controlled to be valid from a specific time & date and duration.
The “Locks” tab shows any paired locks and access information, logs and synchronisation options. The “Clients” list shows all cards and user number in alphabetic order. The User pins are shown unless a nickname is added in which case this is displayed instead.
The lock is very easy to operate and programme. There is a possibility of number repetition if the button is pressed for too long a duration, so a quick press of each button is advisable.
Mobile phone access requires the app to be loaded onto each user’s mobile device and Bluetooth to be enabled so that permissions can be communicated.
The reader can handle up to 150 smart cards (MIFARE Classic 13.56MHz), 100 phone clients and 100 User codes.
If three incorrect codes are entered the keypad will be disabled for approximately 10 seconds to deter repetitive entry attempts. Up to ten code-free periods can be set.
These allow the door to remain unlocked for a set period on any specified day of the week, for example 9:30 to 17:00 Monday to Friday.
A full Factory default can be performed by disconnecting the batteries and reconnecting with a specific key entry.
Battery life is stated to be around 10,000 operations; a low-battery warning is given when these need changing.
A simple to install, flexible door lock system for glass doors, supported by good installation, programming and user documentation.
