Aritech AS2364 Addressable Loop-Powered Fire Sounder

1. Product Name: Aritech AS2364 Addressable Loop-Powered Fire Sounder

2. Description:

What Is the Aritech AS2364 Addressable Fire Sounder?

The Aritech AS2364 is an addressable fire sounder with a red housing and deep base, designed for systems using the 2000 series addressable fire protocol. It is powered directly from the 2-wire loop, so it does not require a separate power supply or additional power cable. Its IP65-rated housing makes it suitable for use both indoors and outdoors.

Operating Principle

The sounder communicates with the fire panel via the loop, and its address is set using DIP switches. When it receives an alarm command from the panel, it produces the preselected tone; during installation, one of 32 different tone settings can be selected to suit local requirements. Panel-controlled automatic phase synchronisation ensures that sounders in the same area operate in unison, avoiding sound confusion and making the alert clearer.

Role in Fire Detection Systems

In an addressable fire detection system, detectors and call points detect the fire, while the AS2364 alerts building occupants audibly to initiate evacuation. It supports multi-stage evacuation scenarios with up to three preset tones; for example, different tones can be used for "alert" and "evacuation" warnings. The sound output is monitored by the panel, so the device's status is continuously supervised.

Why Choose It?

• Loop-powered design: No additional power cable or external supply is required, simplifying wiring and reducing installation costs.
• High sound output with low current consumption: Delivers high sound output with low current consumption, reducing the need for battery backup and lowering overall system costs.
• Flexible tone selection: With 32 tone settings and support for 3-stage evacuation, it meets the requirements of different countries and project specifications.
• Automatic synchronisation: Panel-controlled phase synchronisation ensures that all sounders operate in unison.
• Durable and certified: The impact-resistant polycarbonate housing, IP65 protection and EN54-3 certification make it suitable for demanding environments.

Installation and Commissioning

Wiring connections are made to the base; the sounder body is then fitted and locked into place. This allows wiring and device installation to be carried out in separate stages, reducing the risk of damage to the device on site. The base includes a separate earth terminal for connecting the cable screen or functional earth when required. The device is supplied with high/low sound level adjustment as standard; the final sound level can be set on site during commissioning. The address is assigned using DIP switches, after which the tone and stage settings are checked via the panel.

Compatible Products

The AS2364 is used with Aritech 2X-A series fire alarm control panels that use the 2000 series addressable protocol. Where visual alerts are required, it can be used with the AS36RIM beacon plate, which fits over the sounder and is marked "Fire". It also works seamlessly on the same loop with 2000 series addressable detectors and call points.

Frequently Asked Questions

Does the AS2364 require a separate power supply? No. The sounder is loop-powered; it draws power from the 2000 series loop.

Can it be used outdoors? Yes. Its IP65-rated housing makes it suitable for indoor and outdoor use; the operating temperature range is −10 to +55°C.

Can the sound level be adjusted? Yes. High/low sound level selection is standard, and the adjustment range is typically 8 dB.
