• Frequency & range: Multiple region‑specific frequency bands supported; open‑space range up to 1,700 m depending on environment and local regulations.
• Power & control: Automatic power control to meet region ERP limits (up to 25 mW where allowed) and support for ReX / ReX2 repeaters to extend coverage in larger sites.

• Power supply: 2 × CR123A (pre‑installed). This simplifies first‑time setup and replacement cycles.
• Battery life: Up to 7 years in typical usage scenarios — attractive for low‑maintenance installations.
• Operating conditions: 0 °C to +50 °C and up to 80% non‑condensing humidity — suitable for most indoor environments.

• Dimensions: 102 × 104 × 39 mm; Weight: 214 g. Compact and unobtrusive while still clearly visible on a wall.
• Mounting: Wall‑mounted with mounting tamper detection.
• Compatibility: Works with Ajax Hubs (Hub Plus, Hub 2, Hub Hybrid, Hub BP) — always verify firmware compatibility during planning.
• Protective lid: Transparent lid is optional; recommended where accidental triggers are a concern (e.g., high traffic areas).
• CMS reporting: Configurable through the Ajax system; behaviour may vary by colour/variant and by regional settings.

Practical Benefits for Installers and End Users

• Reduced installation time and cost compared with wired manual call points — no conduit or wiring back to a control panel.
• Lower long‑term maintenance due to long battery life and resettable activation element.
• Flexible integration: use as a conventional manual alarm point in fire scenarios, or as an automation trigger (e.g., unlock doors, switch emergency lighting, activate procedures) in non‑life‑safety uses.
• Secure communications and anti‑spoofing reduce the risk of false activations or malicious interference.

Use Cases and Ideal Scenarios

The Ajax Manual Call Point (Green) is versatile and suits a range of indoor applications:

• A simple way to add a manual alarm point to high‑risk areas inside multi‑dwelling buildings, small offices, or retail outlets without having to retrofit mains wiring.
• Ideal for landlords and managed properties seeking quick installs or retrofits with minimal disruption.

• Classrooms, corridors, and communal spaces can be equipped with conspicuous manual call points that integrate directly with existing Ajax systems.
• The resettable element reduces device replacement costs in environments where accidental activations may occur.

• For office fit‑outs, temporary installations, or phased builds, wireless manual call points allow staged deployment without rewiring.
• Integrators can combine fire mode for life‑safety with Scenario Trigger mode for automation workflows, providing multi‑purpose utility from a single device.

How It Compares to Similar Products

When assessing the Ajax Manual Call Point against alternatives, consider three broad comparisons: wired manual call points, other wireless manual call points, and other Ajax variants (colour/feature differences):

• Wired manual call points:Traditional wired units connect directly to a fire panel and are often mandated in regulated systems. Wired devices avoid battery replacement but require cabling and may be more costly to retrofit. The Ajax unit offers installation speed and reduced disruption at the expense of requiring careful compliance checks for regulated life‑safety installations.
• Other wireless manual call points:Wireless devices vary by range, battery life, reset method and security. The Ajax unit stands out with encrypted two‑way Jeweller communications, support for repeaters (ReX/ReX2), and a resettable frangible element — features that place it at the higher‑end of wireless manual call points.
• Other Ajax variants:Colour variants and CMS reporting behaviour can differ; the green variant is typically intended for specific use or local regulatory marking. Always confirm the appropriate colour/variant for your region and intended use.

Customer Feedback & Typical Installer Impressions

While specific user reviews for this exact part number may vary, installers and system integrators who work with Ajax devices commonly report the following observations:

• Ease of installation: Wireless pairing with Ajax Hubs and long battery life make site visits infrequent and commissioning straightforward.
• Reliability and security: Two‑way encrypted communications and tamper detection increase confidence in device integrity and reduce nuisance alarms.
• Resettable design: The included reset tool is often praised because it removes the need to replace frangible elements after activation, simplifying maintenance.
• Regulatory caution: For regulated fire systems, professionals emphasise checking certification, frequency band compliance, and CMS reporting settings in advance.

If you are evaluating this device for a regulated life‑safety deployment, request certification details and a compliance statement from your supplier and confirm that the unit meets local codes for fire alarm manual call points.
