Device type: Addressable manual call point (MCP) designed to connect to addressable fire detection and alarm systems.

Operating voltage: DC 17 – 28 V.

Quiescent (stand‐by) current: ≤ 400 µA (for model 660‑001)

Alarm current: ~2 mA at activation.

Usable device addresses per loop: up to 125.

Operation type: “Direct operation (Type A)” as defined in EN 54‑11 (i.e., the change to alarm is automatic once the element is actuated).

Indicator: Red LED for alarm indication (illuminates when activated).

Loop isolator: Optional integral isolator available on some models (not specified for 660‑001) to maintain downstream loop integrity in event of short‑circuit.
Environmental conditions:

• Operating temperature: –10 °C to +55 °C.

• Operating humidity: 0 %–95 % RH (non‑condensing)

Dimensions: 87.5 × 87.5 × 56.5 mm (height × width × depth approx).

Wiring terminals: Accepts conductors sized 0.4 – 2.5 mm².

Compliance/Standards: Model 660‑001 complies with EN 54‑11 (manual call points) and EN 54‑17 (short‑circuit isolators) – though isolator version may differ.
