I want to be informed if my front door is opened by my child or elderly relative. What Honeywell doorbell kits are suitable?

Honeywell offers Door Entry Kits, which come with a wireless doorbell, a wireless push button, and a wireless door and window sensor, which are all pre-linked in the box. Opening the door will trigger the sensor, and in turn cause the doorbell to emit an alert sound. The product codes for these kits are either DC313xDE or DC915xDE. Product availability may differ from country to country.

Alternatively, Honeywell offers a wireless door and window sensor HS3MAG1x (Single Pack) / HS3MAG2x (Twin Pack) that can be linked to your existing Honeywell wireless doorbell, and this can also be configured to provide an alert sound.

Which orientation should I use to install the wireless door and window sensors?

Any orientation will do, provided the distance between the sensor and magnet does not exceed 10mm

ka_installing_config_door_window_sensor_4

Does it matter which side of the wireless door and window sensor the magnet is mounted on?

No, but Honeywell recommends that you mount the sensor (big part) on the fixed frame of the door or window, and the magnet (small part) on the window or door itself.

ka_installing_config_door_window_sensor_3

After the sensor has been installed with the keypad, open that door/window, wait a few seconds, then close again. This should set correctly the 'open/close' status of the door or window at the keypad.

One of my sensors is not communicating with my Honeywelll home alarm system. What could be the issue?

Check to see whether:

  1. Are the batteries low or flat? If you have recently replaced the batteries, have you replaced them using the correct battery type and orientation?
  2. Is the sensor mounted within operating range of the keypad? You might need to install them closer to the keypad.
  3. Is the door made of PVC? PVC doors and windows are often a problem. They have metal reinforcement and this will shield or totally block the transmitted signals.
  4. Metal items such as radiators, mirror backing or foil backed plaster board situated between the transmitter (sensor) and the receiver (keypad or siren) can block the signals.
  5. Please note that the operating distance of the sensors and other devices is reduced by the materials the wireless signal has to pass through. For example, internal walls may give around 20% reduction but this depends on the make up of the wall itself. The effect on the range of multiple walls is cumulative. For example, if there are 2 walls in the way, the range will potentially be reduced by up to 40% by each wall. Please refer to the table below for the attenuation characteristics of different types of materials.
Wall TypeRange Reduction
Dry-lined partition wall:10 - 30%
Single layer brick wall:20 - 40%
Double layer brick wall:30 - 70%
Metal panel/radiator:90 - 100%

 

I have a Honeywell Quick Start Alarm Kit (Siren-based alarm). How do I link additional sensors to the Siren using the remote control key fob? Or how do I re-link existing sensors?
  1. Place the Siren into Service Mode by pressing and holding the 'Disarm' button ka_disarm on your remote control for 5 seconds. The Siren will produce 2 short beeps followed 1 second later by a single long beep. The Siren LEDs will flash together in conjunction with the beeps.
  2. Place the Siren into Learn Mode by pressing and holding the 'Arm' button ka_arm on your remote control for 5 seconds.
  3. The Siren will emit a single short beep and both the Comfort LEDs and the Learn LED will flash together slowly once every 2 seconds. The Siren will remain in Learn Mode for 30 seconds.
  4. To link a new wireless motion sensor, either remove the battery isolation tab from the sensor, or push the tamper button, located inside the battery compartment on the back of the sensor.

    ka_linking_a_new_motion_sensor_5 ka_linking_a_new_motion_sensor_6

  5. To link a new wireless door and window sensor, either remove the battery isolation tab from the sensor, or slide open and close the battery cover.

When I press the ‘Arm’ or ‘At Home Zoning Mode’ button on the keypad, the keypad plays an alert sound, and the Open Door Window Sensor LED lights up, along with a Zone number (1-3). What should I do?

This means that a door or window in that zone has been left open.

If you wish to leave the door/window(s) open then you can force arm the system by pressing Arm ka_arm/Home ka_at_home_zoning_mode button on the keypad a second time.

Otherwise please first go and close the relevent door/window(s) before continuing to arm the system by pressing the Arm ka_arm/Home ka_at_home_zoning_mode button on the keypad.

Why does the keypad not alert me immediately that a Zone 1 door/window has been left open when I try to arm the system using the keypad?

All wireless door and window contact sensors in Zone 1 have a 5 minute delay before alerting the keypad that they have been left open.

Typically when a family of 2 or more occupants leave the home, the first occupant will open the door to exit and then leaves the door open until the last occupant presses the 'Arm' button  ka_arm, which starts the 30 second countdown, before closing the front door. The 5 minutes will give enough time for all occupants to exit the home via the front door.

Therefore if you have opened a window or another door in Zone 1 less than 5 minutes before pressing the 'Arm' button ka_arm, the system will not alert you, and will continue to arm itself.

Zones 2 and 3 however are instant and will alert you instantly if any doors/windows have been left open when you press the 'Arm' button ka_arm on the keypad.

Why does the keypad not alert me immediately that a Zone 2 or 3 door/window has been left open when I try to arm the system using the keypad? Or why does the wireless door and window sensor not trigger the alarm?

Try one of the following solutions in this order:

  1. Ensure that the sensor is within effective radio range of the Keypad and is not mounted close to metal objects which may interfere with the wireless radio transmission.
  2. Ensure the battery isolation tab has been removed from the side of the sensor.

    ka_linking_new_magnetic_door_window_sensor_5

  3. Ensure that the gap between the Magnet and Sensor is no more than than 10mm.

    ka_positioning_the_door_window_sensor_4

  4. Check and replace the battery in the door and window sensor.

    If the above does not work, try a walk test.

  5. Perform a walk test to ensure the ID of the sensor has been learnt into a zone (1-3). First, enter Test mode on the keypad by pressing the Disarm (insert icon) button on the keypad, followed by swiping a contactless tag or entering your PIN code. The keypad will respond by playing a melody. Now press the number 1, then walk around and open and close any windows or doors that you want to test. If the sensors are linked to the keypad, the keypad will play an alert sound and indicate the Zone number. If not, there will be no response from the keypad, and you will have to re-link the sensor to the keypad. To exit Test mode, press the Disarm button once again.

My wireless door and window sensor does not indicate a correct open or close status at the keypad. How can I fix this?

First, open the door or window where the new sensor has been installed, and wait for 2 seconds before closing it. Now you can arm the system.

Similarly if that door or window is already open, then close it and wait for 2 seconds or more before arming the system. This will allow the keypad to register the correct status of that sensor and thereafter during ongoing operation.
