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 85–107 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. NFA2P, VdS and Regular tones are listed in the current specification.
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.
Wired supply with a larger backup battery.
8–28 V DC from the hub
The current specification lists up to 50 mA at nominal 24 V and a 16–18.5 V start-up range. A rechargeable 2.4 V, 3,000 mAh LTO battery is charged from Fibra and supports alarm indication if line power is lost.
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.
A protected outdoor enclosure
For outdoor or indoor use from −25 to +60 °C and up to 95% humidity without condensation. The enclosure is rated IP54 and IK08. Preserve its protection when routing cables and closing the mounting.
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.
