FAQs

What is the difference between Ajax Kit 21 Superior and Kit 23 Superior?

The primary difference between Kit 21 and Kit 23 lies in the motion detection technology employed. Ajax Kit 21 Superior uses two Superior MotionProtect S standard motion detectors featuring advanced PIR sensing with SmartDetect algorithms and pet immunity, but without visual alarm verification capability. Ajax Kit 23 Superior uses two Superior MotionCam S (PhOD) motion detectors that add photo verification functionality, capturing and transmitting images when motion is detected to provide visual confirmation of alarm events. Both kits include identical components otherwise: Hub 2 (2G), one DoorProtect S door contact, one Superior KeyPad Plus S keypad, Superior StreetSiren DoubleDeck S outdoor siren, and Superior HomeSiren S indoor siren. Kit 21 represents a more cost-effective solution for installations where photo verification is unnecessary or where budget constraints prioritize essential motion detection. Kit 23 provides enhanced alarm verification particularly valuable for reducing false alarm responses by security companies and enabling users to visually assess threats before dispatching emergency services. The choice depends on whether visual alarm confirmation justifies the additional investment in MotionCam technology.

How does the Superior KeyPad Plus S provide advanced access control?

The Superior KeyPad Plus S delivers sophisticated authentication through multiple access methods and code types. The keypad supports DESFire contactless cards and Tag key fobs utilizing 128-bit encryption based on ISO 14443 international standard, the same technology employed in transportation systems of European capitals and NASA access control. This virtually unhackable contactless technology prevents card cloning and unauthorized duplication. The keypad accommodates multiple PIN code types including keypad code (general system code), user codes (personal codes linked to individual accounts), access codes (for persons not registered in system such as cleaning staff), duress codes (triggering silent alarms while appearing to disarm normally), and rapid response unit codes (activated only during alarm conditions for limited time periods). Each code type serves specific security requirements with all access events logged including user identity, timestamp, and action performed. The keypad automatically locks for 3-180 minutes (configurable) after three incorrect code attempts within one minute, preventing brute force attacks. Auto-wake on delay when entering function can automatically activate the keypad when users approach during exit delay periods, streamlining operation. Battery life reaches 4.5 years when contactless reader is disabled or 3.5 years with reader active.

What are the advantages of standard MotionProtect S detectors versus MotionCam detectors?

Superior MotionProtect S standard motion detectors offer several advantages over MotionCam variants for specific applications. Cost effectiveness represents the primary benefit, reducing system investment when photo verification is deemed unnecessary for the facility’s security requirements. Battery life extends up to 7 years on MotionProtect S detectors compared to 3-5 years on MotionCam variants, reducing maintenance frequency and lifetime operating costs. The detectors employ SmartDetect digital signal processing algorithms that analyze PIR sensor signals to distinguish genuine human motion from false alarm sources including pets, drafts, moving curtains, and heating system interference. Pet immunity reliably ignores animals up to 44 lbs and under 1.6 ft tall when detectors are installed at recommended 8 ft height with lens facing potential intrusion paths. Temperature compensation maintains detection sensitivity even when ambient temperatures approach human body temperature. For installations prioritizing immediate intrusion detection without visual confirmation requirements, standard motion detectors provide reliable performance with reduced complexity. Facilities with minimal false alarm concerns, budget-sensitive projects, or environments where privacy considerations discourage camera usage benefit from MotionProtect S technology. The detectors integrate seamlessly with other Superior components while maintaining Grade 2 certification and professional reliability standards.

Can photo verification be added to this system after initial installation?

Yes, the Ajax Kit 21 Superior can be upgraded with photo verification capability after initial installation by adding Superior MotionCam S (PhOD) detectors to the system. The Hub 2 (2G) included in Kit 21 supports photo verification through its Wings wireless protocol implementation, enabling seamless integration of MotionCam detectors alongside existing MotionProtect S detectors. Installers can replace the two included MotionProtect S detectors with MotionCam S units, or add MotionCam detectors to additional zones while retaining the original motion detectors in areas where photo verification is unnecessary. The system supports mixing device types, allowing cost-effective deployment of expensive MotionCam technology only where visual confirmation provides maximum value. Adding MotionCam detectors requires purchasing the devices separately and pairing them to the system through QR code scanning in Ajax PRO Engineer App. All photo verification features including photo on demand, photo by schedule, photo by scenario, and photo by arming/disarming become available once MotionCam detectors are added. Privacy settings can be configured per detector, controlling which users can request photos and view received images. This upgrade path allows facilities to start with Kit 21’s cost-effective standard motion detection then add photo verification capability as security requirements or budgets evolve.

What communication channels does the Hub 2 (2G) support and how does failover work?

The Hub 2 (2G) maintains connectivity through three independent communication channels: Ethernet (up to 100 Mbps), and two 2G SIM card slots supporting different mobile network operators. Communication channels operate in parallel to maximize system reliability, with most data transmitted via Ethernet when available. Automatic failover switching between Ethernet and SIM cards occurs within seconds when a primary connection fails. The hub continuously monitors all communication paths and instantly switches to alternative channels if one becomes unavailable due to internet outage, cable damage, or network issues. Between the two SIM card slots, switching occurs within 4 minutes, while switching between Ethernet and cellular occurs instantly. This redundancy ensures alarm notifications reach security companies and end users even during infrastructure failures. The hub also monitors for communication jamming attempts and notifies users if radio frequency interference is detected. Battery backup (Li-ion 2 Ah) provides up to 16 hours of autonomous operation during mains power failure when Ethernet is disabled, allowing continued system operation and cellular communication during blackouts. Users can configure which SIM card serves as primary and which as backup, and monitor cellular data consumption through Ajax apps.

Is this kit expandable and what is the maximum system capacity?

The Ajax Kit 21 Superior is highly expandable within the Hub 2 (2G) capacity of up to 100 connected devices. The system supports combining devices from all Ajax product categories including additional intrusion protection devices (both Superior and Baseline lines), video surveillance components (up to 25 cameras or NVRs), fire and life safety detectors, and comfort/automation devices. Specific device limits include up to 10 sirens or keypads with built-in sirens, and up to 5 radio signal range extenders to overcome signal obstacles in large facilities. The hub supports up to 50 user accounts with customizable access rights, 9 security groups for independent zone management, and 32 automation scenarios for programmable system responses. Common expansions include adding Superior MotionCam detectors for photo verification in critical zones, additional MotionProtect or DoorProtect detectors for comprehensive coverage, glass break detectors, water leak sensors (LeaksProtect), smoke and CO detectors (FireProtect 2), and SpaceControl key fobs for users preferring physical access devices. Superior and Baseline product lines are fully compatible, enabling installers to deploy Superior devices where enhanced certifications are required while using cost-effective Baseline components elsewhere. Ajax’s range extenders boost wireless coverage to 2,000 meters, enabling protection of multi-building campuses or facilities with thick walls and metal structures. The system architecture supports gradual expansion with new devices added remotely through QR code scanning.
