None. Both alarm systems are compatible with the same range of accessories.

However, the PA501Z control panel is also compatible with our range of Zigbee accessories. These accessories cannot be paired with the SA501 control panel.

You can add up to 200 accessories to your system.

If your chosen alarm system is missing any accessories to fully meet your needs, you can freely add them to your order from the accessories page.

You can also add to your system as your needs evolve!

No. On our website, you will find the SA501/PA501Z and AM301 alarm system ranges. These ranges have their own accessories and are not compatible with each other.

So you cannot add AM301 accessories to your PA501Z system and vice versa.

Please note that the SA501 and PA501Z series are compatible with the same accessories. In addition to these accessories, the PA501Z also has Zigbee compatibility with dedicated accessories.

The vibration detector, as its name suggests, is triggered when it detects a vibration. It is therefore ideal for protecting large glass surfaces that could be broken to allow intrusion.

The WDS501 door switch, on the other hand, only activates when it's open. It works perfectly for a front door. However, if you've positioned it over a window and it's broken and not open, your detector won't alert you to an intrusion.

These two accessories can be used together, for double security.

The entire PA501Z accessory range operates on batteries. These are supplied with your accessories.

The only accessories that require mains power are the WIS501 and WIS502 indoor sirens and the WOS501 outdoor siren.

You can, however, opt for the WOS501S solar outdoor siren, which operates using an included solar panel.

This badge only allows you to disarm your alarm system. It is ideal for children because it prevents false activation.

Added to your PA501Z control panel, it will only be compatible with the WKE501 or WKE502Z wireless keypad (zigbee version) which have an RFID reader.
