Quantec PIR Power Interface with Isolating Keyswitch
£65.75 (inc VAT: £78.90)
Summary
The Quantec PIR Power Interface with Isolating Keyswitch (QT645) is designed to integrate PIR movement sensors into Quantec addressable call systems, making it ideal for healthcare and care home environments. This interface allows up to two QT638 PIR movement sensors to be connected to a Quantec system via a QT602 or QT609 Range Call Point.
Typically installed outside a bedroom, the QT645 enables effective patient monitoring by detecting movement when a patient gets out of bed. The integrated isolation keyswitch provides staff with the flexibility to temporarily disable PIR monitoring when entering the room, preventing unnecessary call activations whilst maintaining system functionality.
Designed for ease of installation, the interface derives its power directly from the Quantec network, eliminating the need for a separate power supply unit. The compact unit mounts on a standard UK 25mm single gang flush or surface back box, and up to 16 QT645 interfaces can be connected to a single Quantec system.

FAQ
How many PIR sensors can be connected to one QT645 interface?
Each QT645 PIR Power Interface can connect up to two QT638 PIR movement sensors to your Quantec addressable call system.
Does the QT645 require a separate power supply?
No, the QT645 derives its power directly from the Quantec network, eliminating the need for a separate power supply unit. This simplifies installation and reduces cabling requirements.
What is the purpose of the isolation keyswitch?
The isolation keyswitch allows staff to temporarily disable the PIR monitoring when entering a patient’s room. This prevents the PIRs from triggering unnecessary calls whilst staff are attending to the patient.
How many QT645 interfaces can be installed on one Quantec system?
A maximum of 16 QT645 PIR Power Interfaces can be connected to a single Quantec system, allowing comprehensive coverage across multiple rooms.
What type of back box is required for installation?
The QT645 mounts on a standard UK 25mm single gang flush or surface back box, making it compatible with standard UK electrical installations.
What are the operating temperature and humidity limits?
The QT645 operates in temperatures ranging from -5°C to +40°C with a maximum relative humidity of 95% non-condensing, making it suitable for typical indoor environments.
