Frequently asked questions

How to?
Can I use more than one Siren with the same Keypad?

Yes. This will allow you to place Sirens in distant parts of the property outdoors.

Please visit the Accessories section to view these products. The sirens available are dummy siren (HS3DS1x), wireless battery siren (HS3BS1x), and wireless solar siren (HS3SS1x)

What should I do when the LED indicators on the Battery Siren (HS3BS1x) are not working?

Try one of the following solutions in this order:

  1. Open the rear battery cover and ensure the battery isolation tab has been removed. The LED indicators should flash together once, then start flashing alternately once every 5 seconds.

  2. If Step 1 does not work, check the polarity of the Alkaline batteries. If this works, the LED indicators should flash together once, then start flashing alternately once every 5 seconds.
  3. If Step 2 does not work, you may need to replace the batteries. After replacing the batteries, the LED indicators should flash together once, then start flashing alternately once every 5 seconds.

The Siren should have now been powered up in Service Mode. You will now need to switch the Siren back into Operating Mode.

For Siren-based Alarm Kits:
Exit Service Mode by pressing and holding the 'Disarm' button ka_disarm on your remote control for 5 seconds. The Siren will produce 1 long beep followed 1 second later by 2 short beeps. The Siren LEDs will flash together in conjunction with the beeps.


For Keypad-based Alarm Kits:

  1. Enter Test mode by pressing the disarm ka_disarm button on the keypad, followed by swiping a contactless tag or entering your PIN code. The keypad will respond by playing a melody.

  2. Press the number 9 on the keypad. The siren will produce 1 long beep followed by 2 short beeps to confirm that it is now in Operating mode.

  3. Press the disarm button again on the keypad to exit Test mode. The keypad will play a melody once again to confirm.

Why is my alarm siren not activating even when multiple sensors have been triggered?

If the alarm has been triggered more than 3 times in a specific Zone, then Zone Lockout could have occurred, which would prevent the alarm from being triggered again by any sensors in that Zone. To reset the zone, you can Disarm the system, and then Arm the system again.

What Guarantee does Honeywell offer on the range of Doorbells, Alarms and accessories?

Honeywell Home offers a 2 year Guarantee on all Doorbell kits, Alarm kits, and accessories.
