KPT-35N-BUS

WIRED KEYPAD

KPT-35N-BUS is a hardwired keypad with an NFC key fob designed to have quick access control of the system control panel via PIN Code or NFC tags. The keypad can send wired signals to and receive signals from the Control Panel within wire distance, depending on the wire gauge and the total power consumption of all wired devices. The LCD screen will display information the system control panel sends back.

The wired keypad can be mounted on either a flat surface or a wall with screws, or placed on the desktop with the enclosed bracket. It also has a tamper protection switch which will be activated upon any unauthorized attempt to open the back cover.

Features

Power Supply Input

When KPT-35N-BUS is hardwired to Control Panel, 13.5V (typical) power supply can be provided by the Control Panel to KPT-35N-BUS.

Power Saving Feature

  • When idle, the wired keypad is in stand-by mode and consumes no power. It wakes up when any key is pressed.

  • After accessing the User Menu, if neither the Arm key nor the Home Arm key is pressed, the wired keypad will return to stand-by mode automatically.

  • If no key is pressed after “Enter PIN Code” message appears on the LCD screen, the wired keypad will return to stand-by mode.

  • Upon completion of a command input, the wired keypad will return to stand-by mode.

Tamper Protection

  • The wired keypad is protected against any unauthorized attempts to open the back cover with a tamper switch. When the back cover is opened, the tamper switch will be triggered, and the wired keypad will transmit a tamper open signal to the system control panel.

  • After re-placing the back cover, the wired keypad will transmit a tamper restore signal to the Control Panel.

  • When the wired keypad is properly mounted with the back cover screwed onto the wall, removing the keypad forcefully will break off the back cover from the hollowed section around the screw location and activate the tamper switch.

Supervision Signal

  • The wired keypad will automatically transmit Supervision Signals to the Control Panel at intervals of 75 seconds.

  • If the Control Panel has not received the signal from the wired keypad for a preset period, the Control Panel will consider the wired keypad out of order and react according to the panel settings.

Caution

  • Wiring of the wired keypad should only be performed by certified technicians with proper knowledge and training in electric equipment.

  • Before installation or any maintenance work, make sure the power supply has been disconnected.

Keypad Wiring

  • Before connecting the keypad to the system bus, please switch the power off.

  • To connect KPT-35N-BUS to the Control Panel, open the front cover by using a Phillips screwdriver to loosen the cover fixing screw.

  • Loosen KPT-35N-BUS’s “V” terminal and the Control Panel’s “VDD” terminal. Connect the “V” terminal to the “VDD” terminal and tighten both terminal screws.

  • Loosen KPT-35N-BUS’s “G” terminal and the Control Panel’s “GND” terminal. Connect the “G” terminal to the “GND” terminal and tighten both terminal screws.

  • Loosen KPT-35N-BUS’s “A” terminal and the Control Panel’s “485A” terminal. Connect the “A” terminal to the “485A” terminal and tighten both terminal screws.

  • Loosen KPT-35N-BUS’s “B” terminal and the Control Panel’s “485B” terminal. Connect the “B” terminal to the “485B” terminal and tighten both terminal screws.

  • Power on the Control Panel and wait for the “KPT-35N-BUS” to be shown on the wired keypad’s LCD screen.

  • The keypad terminal can be hardwired to the Control Panel. Up to four KPT-35N-BUS can be connected in series. The maximum wire cable length depends on the wire gauge and the total power consumption of all wired devices, for example: a maximum of 3000ft with 22-AWG cable for one KPT-35N-BUS; a maximum of 1500ft with 22-AWG cable for 2 KPT-35N-BUSs; or a maximum of 1000ft with 22-AWG cable for 3 KPT-35N-BUS.

  • In the picture below, KPT-35N-BUS-A and KPT-35N-BUS-B are wired correctly in series, as the total wire distance of the two keypads from the Control Panel is within 1500ft. For KPT-35N-BUS-C in the picture below, it is NOT wired correctly, as it is farther than 1000ft from the Control Panel.

  • For optimal communication on the BUS network, enable the Terminal Resistor Jumpers only at both endpoints (the two farthest nodes) to prevent signal reflection and improve communication stability. Do not enable jumpers on any intermediate BUS devices—only the two endpoints should have them enabled.

  • In the example below, the Control Panel and the KPT-35N-BUS-B are the two farthest endpoints. Please enable the J53 Jumper Switch on the Control Panel and the terminal resistor jumper on the KPT-35N-BUS-B.

Learning

Please follow the steps below to learn the keypad into the Hybrid Panel.

Step 1. After connecting the keypad to the Hybrid Panel, power the Panel on, and the keypad will also be powered on.

Step 2. On the keypad’s LCD, choose a located area and a free zone to add to the Panel.

Step 3. Enter the User PIN Code of the located area.

Step 4. Enter Installer Code. (Factory Default: 7982)

Step 5. The keypad is added to the located area and the zone you chose.

User PIN Code Management

To configure the KPT-35N-BUS for multi-area mode change with the system, please go to the Panel’s PIN Code (NEW) page to manage user PIN codes. This page allows you to set up and manage PIN codes across multiple areas.

A user PIN code must be unique, even across areas. Therefore, when a PIN code is assigned for multiple areas, the system will automatically add the area number as the first 2 digits. Please manage user PIN codes on PIN Code (NEW) page, and the system will update the PIN Code page accordingly.

For example, if you assign 1234 to both Area 1 and Area 2 on PIN Code (NEW) page, the system will update the PIN to 011234 for Area 1 and 021234 for Area 2 on the PIN Code page.

A PIN Code assigned to multiple areas must be limited to 4 digits in PIN Code (NEW) page, as the system will automatically add the area number as the first two digits in PIN (Code) page.

On the other hand, a PIN Code for a single area can be set up to 6 digits.

Add Tag/Clear Tag Procedures

The keypad can transmit NFC (Near Field Communication) tags to the Control Panel. You can assign a PIN code and user name to each NFC tag via the Panel's webpage. These tags can then be used to control the alarm system mode through the keypad. The number of NFC tags and PIN codes is also managed on the Control Panel webpage.

Since each tag can only be assigned to a unique User ID for a specific area, it does not support mode changes across multiple areas.

A. Add Tag:

When adding a new tag, the keypad must be in normal operation mode.

Step 1. After setting up User PIN codes on the PIN CODE (NEW) page, go to the PIN Code page to manage NFC tags.

Step 2. Once KPT-35N-BUS is successfully learnt into the Panel, press the OK key on the keypad. Then, place a new tag to the Keypad Tag sensor zone. “Incorrect PIN Code” will be displayed to indicate this tag is new (not added to the system yet).

Step 3. Click the Load button on the PIN Code page as below. The corresponding tag number will be loaded. You can input a user name, and then click Submit to save the tag.

Step 4. The tag has been added. You can use the tag to arm/home arm/disarm the system.

B. Clear Tag:

Step 1. Go to the PIN Code page on the Control Panel webpage.

Step 2. Manually delete the tag number and click Submit.

Step 3. The tag is cleared.
