- 1From 3 seconds to 3 minutes.
- 2For the Chime feature to work, the system requires an opening detector. Learn more about Chime.
- 3When the U/UTP cat.5 4×2×0.51 mm (24 AWG) cable is used. Other cable types may have different values. Please use the Fibra power supply calculator to check the wired system project before installing the device. Cable type, topology, connected load and voltage drop determine the usable line length.
- 4This means that up to 10 sirens, including keypads with built-in buzzers, can be added to the system.

Know what the system is telling you.
Draw attention to an alarm
Choose which system devices should activate the siren and configure its response to tamper and panic events. Sound and light can alert people nearby; notifications and any monitoring response depend on the connected system and service settings.
A gentle signal for everyday arrivals.
Chime while the system is disarmed
A short notification can announce an opening detector being triggered. Configure the siren and the relevant device, then test the event and volume. This signal informs people of an arrival without treating it as an intrusion alarm.
Set the alarm and its visual feedback.
Set the sound for the site
Choose an alarm volume within 81–105 dB at 1 m and a duration from 3 seconds to 3 minutes. Notification beeps can be adjusted separately. Test audibility in the actual space rather than relying only on the maximum figure.
A supervised connection on the Fibra line.
Up to 2,000 m on a four-core cable
Fibra carries alarms, commands and status over a supervised wired connection. The maximum line length assumes U/UTP cat.5 cable. Cable type, topology, connected load and voltage drop determine the usable installation.
An accredited Ajax partner should calculate the line load and check the exact siren’s operating and start-up voltage. A ring connection has different length limits; a backup battery does not restore communication across a severed line.
Power directly from the Fibra line.
No internal battery
The siren operates from 7–26 V DC, with a current specification of up to 1,811 mW and 75.5 mA at nominal 24 V. Start-up requires 16–18.5 V. Include its alarm load in the line calculation and verify voltage at the installed device.
Protection that also watches itself.
Monitor the enclosure and mounting
Two tampers report unlocking SmartBracket and detachment from the mounting surface. Fit the required fasteners and test the event at the end of installation.
Supervise the connection
Regular exchanges allow the hub to detect a missing device and report the affected siren and room. Connection-loss timing depends on the configured polling interval and missed-packet threshold.
Install within the specified conditions.
Indoor placement
Use indoors from −10 to +40 °C and up to 75% humidity. The enclosure is rated IP50 and IK06.
Place it well. Test the complete response.
Check audibility and visibility
Choose a position where the alarm can be heard and the indication can be seen. Use the exact mounting instructions and permanent fixings, secure SmartBracket, and test removal protection. Avoid a location where the sound could trigger a nearby glass-break detector.
