Review: Great little system - and superb customer support - Ordered this system mainly on the strength of the reviews and not disappointed! We bought the Basic House system, 5 PIR sensors, two extra siren units and an extra fob. Easy to set although got lost in the process once or twice but soon resolved. System works well and does what it should. The glaring ommission in the product lineup is the lack of an external house siren but this is going into production as I write. Doubt I would have purchased without this being available as it did render the system much less effective IMHO. I have confidence that the quality of this wiill match the rest of the lineup. Customer support could not be better - unlike many of the larger companies I have had experience of. Highly recommended!!!!!!!!
Review: Starter kit well priced and so far pleased with operation. - Installation and operation could not be easier. All components paired already although help video was very good when pairing additional parts. Wireless range very good though unsure yet how long the batteries will last as I’m stretching their range to the limits. Starter kit very economic though additional pretty expensive by comparison (as one might expect). Only criticism thus far … is the remote is fragile and will consequently need great care.

## Features

- IMPORTANT - Do not use this product in combination with the tiiwee A2 or X4 motion sensor alarm. Combine this siren with the tiiwee TWPIR01, TWPIR02, TWPIR03 and TWPIR04 motion sensors. After purchase, you will receive an email with instructions on pairing the tiiwee home alarm sensors with this new A1 siren.
- Doorbell Sound and 120dB Siren - By factory default, the sound is set to the doorbell tone. Change the sound by pressing the manual settings button directly on the A1 or with remote control. The 120dB siren is loud and is an excellent deterrent to burglars.
- Expand your A1 System - The A1 siren quickly expands your existing A1 based system. You will find a detailed description about it in the tiiwee Home Alarm A1 Starter Kit manual.
- The A1 alarm unit is compatible with the tiiwee Home Alarm A1 Starter Kit. It works wirelessly and comes complete with batteries and mounting hardware - so it can stay mobile and go wherever it's needed.

## Questions & Answers

**Q: Is this compatible with the eray alarm system?**
A: Don’t think so , ask tiwee

**Q: Our current unit has started to go faulty and the sound is very quiet. We need to replace it. Can you pair this with existing door sensors?**
A: Yes, I have done this with my A1 alarm unit. There are two steps: (a) un-pair (if there is such a word) your sensors from the old alarm unit by following the instructions in your manual "Deleting the sensors for one zone", (b) pair your sensors with the new alarm unit, as described in "Entering pairing mode" and "Setup Zone 1" in your manual. It is quite straightforward.

**Q: Can the siren be used outdoors? i.e is it weatherproof?**
A: Dear customer,
no, this siren cannot be used outside. However, we just introduced our new outdoor siren. Please search for B07GXX89V3.

Kind regards,

Gerard G. / Tiiwee

**Q: Have an a1 startkit & extra siren. all pairs up ok, but the remote won't arm/disarm the 2nd siren? it's paired & sounds when activated. any ideas?**
A: Watch you tube video Pairing multiple sensors and remote controls to two A1 alarm units
