What Makes Ajax Alarm Systems Different from Traditional Alarms?
Ajax systems use Jeweller wireless protocol providing 2km range and 7-year battery life, unlike traditional wired systems requiring extensive cabling. The smartphone app provides real-time notifications, system control, and device status monitoring from anywhere.
Key differentiators include:
- Wireless Technology: No drilling through walls or running cables between floors
- Smart Features: Photo verification with Ajax cameras, temperature monitoring, and pet-immune detectors
- Professional Grade: Meets BS EN 50131 Grade 2 requirements for insurance compliance
- Expandability: Add up to 150 devices to a single Hub 2 Plus system
- Backup Communication: Ethernet, Wi-Fi, and cellular connectivity options
Unlike basic DIY systems, Ajax integrates with professional monitoring stations and CCTV systems for complete security coverage.
Do Ajax Alarms Work During Power Cuts?
Yes, Ajax systems continue operating during power outages using built-in backup batteries lasting up to 16 hours. The Hub contains rechargeable batteries, while individual detectors run on long-life batteries unaffected by mains power loss.
The system automatically switches to cellular backup if your broadband fails, ensuring continuous monitoring. Hub 2 Plus models include dual-SIM capability for enhanced reliability. Battery status monitoring through the Ajax app prevents unexpected failures with advance low-battery warnings.
Which Ajax Components Do I Need for My Home?
Essential Ajax components include the Hub 2 Plus, motion detectors for main rooms, door contacts for entry points, and at least one key fob. Additional components like outdoor sirens, cameras, and glass break detectors enhance security based on property requirements.
Recommended configuration by home type:
- Flat/Apartment: Hub 2, 1-2 motion detectors, door contact, key fob (£899-£1,200)
- 3-Bedroom House: Hub 2 Plus, 3 motion detectors, 2-3 door contacts, 2 key fobs, indoor siren (£1,400-£1,800)
- Large Property: Hub 2 Plus, 5+ detectors, multiple contacts, outdoor siren, cameras (£2,000+)
Motion detectors like the Ajax MotionProtect cover 12m range and ignore pets up to 20kg. Door/window contacts provide perimeter protection, while the HomeSiren provides 105dB indoor alerts. For properties in areas like Kensington or Camden, Ajax systems integrate well with existing security infrastructure.
How Reliable Is Ajax Wireless Communication?
Ajax's Jeweller protocol provides highly reliable wireless communication with anti-jamming technology and encrypted signals. The system performs automatic signal strength tests and alerts you to any communication issues before they affect security.
Reliability features include:
- Range: Up to 2km in open space, typically 400-800m in residential buildings
- Battery Life: 7 years average with regular use and temperature monitoring
- Anti-Jamming: Frequency-hopping technology prevents interference
- Signal Monitoring: Continuous connection testing with instant fault notifications
- Backup Communication: Multiple connection paths ensure monitoring continuity
The system works effectively in demanding environments including properties in dense London areas like Lambeth or Kilburn where wireless interference can be challenging.
Can Ajax Systems Connect to Professional Monitoring?
Yes, Ajax systems fully support professional monitoring through alarm receiving centres (ARCs) using standard protocols. The Hub connects via multiple communication paths including broadband, cellular, and backup connections to ensure monitoring continuity.
Professional monitoring benefits include 24/7 surveillance, police response coordination, and compliance with insurance requirements. Many UK monitoring stations now support Ajax systems directly, providing seamless integration with existing infrastructure.
For comprehensive security, Ajax integrates with other systems including Texecom and Pyronix packages depending on specific requirements. Our installation covers areas from Kingsbury to Willesden, ensuring proper monitoring setup for your location.
How Long Does Ajax Installation Take?
Professional Ajax installation typically takes 3-4 hours for an average UK home, including system configuration and user training. Installation time varies based on property size, number of devices, and any integration with existing security systems.
Installation process includes:
- Survey and Planning: Site assessment and device positioning (30 minutes)
- Hub Installation: Central unit positioning and connectivity setup (45 minutes)
- Device Installation: Mounting detectors and contacts throughout property (90 minutes)
- Testing and Configuration: System programming and range verification (45 minutes)
- User Training: App setup and operation demonstration (30 minutes)
Unlike traditional burglar alarm installation requiring extensive wiring, Ajax's wireless nature significantly reduces installation time and property disruption.
