    CAST CA402 Programmable Heat Detector

    The CA402 is a high quality programmable heat detector for use with C-Tec's XFP & ZFP 'CAST' protocol addressable fire panels.

    CAST is the world’s most-advanced 'distributed intelligence’ fire alarm system protocol. Conceived, designed and realised by C-TEC as part of a five-year, multi-million pound project, it involved the creation of a powerful proprietary communication protocol (C-TEC Addressable System Technology, CAST) and multiple control panels & field devices.


    • A high quality programmable heat detector for use with C-Tec's XFP & ZFP CAST protocol addressable fire panels.
    • LPCB certified to EN54-5 & 17 and Kiwa Telefication certified to EN54-13.
    • Can be programmed to operate as a Class A1R (rate of rise), Class A2 (64ºC fixed temperature) or Class B (76ºC fixed temperature) heat detector.
    • Default setting is A2.
    • Onboard short circuit loop isolator.
    • Includes two 8mm x 2mm ultra-bright red LED indicating strips.
    • Different sensitivities can be selected for different times of the day (day/night, building occupied/unoccupied etc).
    • 5mA typical alarm current (370uA typical quiescent) @ 22-40V DC.
    • Programmable multi-function status LED.
    • Compatible with C-TEC's CA408 CAST base c/w integrated locking mechanism & ID tag.


    • Approvals/Certifications : LPCB certified to EN54-5 & 17 and Kiwa Telefication certified to EN54-13
