Flood Sensor (CAST/Hush-Pro Compatible)

Order code: CA741 Categories: CAST Interfaces, Hush-Pro Domestic Interface Units

A C-TEC manufactured flood sensor specifically designed to connect to a CAST or Hush-Pro I/O unit to signal an alarm condition when water is detected.
Mounts vertically with the sensor’s exposed PCB tracks at floor level.
Removable low and side entry bungs allow water to enter the device in a flood situation.
When water is detected the sensor will send an alarm signal to the connected I/O unit which will in turn report it to its CIE.
Resets when the I/O unit is commanded by the CIE to reset its zone circuit.
Compatible with C-TEC’s CA730 CAST I/O module, the CA731 CAST mains switching I/O module, the CA732 CAST zone monitor module, the HP731 Hush Pro FL1 Mains Switching I/O Module and the HP732 Hush Pro FL2 Mains Switching I/O Module.

More Information

‘CAST’ is the world’s most-advanced ‘distributed intelligence’ fire alarm system protocol. Conceived, designed and realised by C-TEC, it involved the creation of a powerful proprietary communication protocol (C-TEC Addressable System Technology, CAST) and multiple control panels & field devices. Its key features include:-

• 255 devices per loop.
• Autonomous decision-making for faster response times.
• Multiple type codes.
• 40V loop drive voltage.
• Two ‘soft’ addressing options – automatic via the panel or manual via a powerful handheld programmer.
• Powerful multi-level addressing facilitates easy device addition and swapped device identification.
• Multiple functionality at a single address (integrated devices) via our CAST-PRO devices.
• Volumes, tones & detector modes can be changed at compatible panels.
• High-speed data transmission and robust data transfer.
• Intrinsically EN54-13 compliant.
• Geographical location of short and open circuit faults (a short circuit isolator is included as standard in every CAST field device).
• Replace device function.
• Future seamless integration with other CAST life safety systems reducing energy, servicing, installation and repair costs.
• Designed and manufactured in the UK.
