Fire Detectors

A smoke detector in rooms and escape routes where early warning matters, and a heat detector where cooking fumes, steam or dust would set a smoke detector off, such as a kitchen. The ESP PSD2 is an optical smoke detector and the ESP FHD2 a heat detector that alarms at 60°C. Multi-sensors such as the Eaton CAPT340 combine smoke and heat sensing to cut false alarms.

A fixed-temperature detector alarms when the air reaches a set point, while a rate-of-rise detector also alarms when the temperature climbs quickly, catching a quickly developing fire sooner. The ESP FHD2 detects temperatures over 60°C (class A2/S), and the ESP RHD2 alarms above 58°C or on a rapid change. The Hochiki ATJ-EN has both elements, and the panel chooses which to use.

A conventional detector tells the panel which zone is in alarm, not which detector, while an addressable detector reports its own location over a loop. Conventional examples here include the FireClass 516.900.001 and the Hochiki DFG-60BLKJ; addressable ones include the MAG MAGPRO-SD1, the Comelit PAC 41RML100B and the Hochiki ATJ-EN. An addressable detector must match the panel's protocol.

Yes, if it is a 12V detector: Texecom makes its Exodus detectors, such as the AGB-0001 optical smoke and AGB-0003 heat detectors, in 12V security panel formats and lists the range as EN54 BSI Kitemark approved. ESP also makes 12V models, the PSD212 optical smoke, FHD212 fixed heat and RHD212 rate-of-rise detectors, alongside the 24V PSD2, FHD2 and RHD2.

With a beam or aspirating detector rather than many point detectors on a high ceiling. The ESP BD1 beam detector covers 50m, extendable to 120m with the BD1LRK, and has laser alignment with Auto Align. The Hochiki FIRELINK-100 aspirating detector draws air through two sampling pipes of up to 100m aggregate length and uses laser sensing that can discriminate against dust.

A sealed heat detector such as the Hochiki DFG-60BLKJ, a conventional 60°C fixed-temperature detector rated IP67 for wet, condensing or hosed-down areas, with LPCB and VdS certification. It needs no separate base and connects on short flying leads. Its bi-metallic element keeps standby current low, and its listing suggests it for industrial, marine and exposed locations.

Yes, for buildings where cabling is hard to run. The Hochiki EK-WL8-O is a wireless optical sensor for the Ekho system, Apollo XPander detectors such as the XPA-CB-13032-APO heat detector talk to a radio interface on the loop, and Cygnus SmartNet radio bases join a network of battery-powered devices. Bull CYG4L detectors are made for site accommodation on construction projects.

Plug-in detectors do, and the base may be sold separately: ESP MAGPRO-SD1, MAGPRO-HD1 and MAGPRO-HSD1 heads fit the MAGPRO-DB base, which is supplied separately. The ESP SD-DB deep base allows surface cable entry or mounting on an uneven surface, and the ESP CSD212 is sold as a detector and base together.

It terminates a conventional detector zone so the panel can monitor the circuit for faults. The ESP MAGEOL zone modules come in packs of 5 for MAG2, MAG4 and MAG816 detector circuits, and the MAGZC-816 card adds 4 detector zones to a MAG816 panel, with up to 32 detectors per zone.

Look for the part of EN 54 that covers the detector type. Point smoke detectors such as the Apollo FL6100-600APO are tested to EN 54-7, and heat detectors to EN 54-5, as the Comelit PAC 41RML100 states alongside EN 54-7 and EN 54-17. The Comelit PAC 45RFU100 also lists EN 54-25, and the Texecom AGB-0001 is EN54-7 compliant.
