Fire Detectors

Fit smoke detectors in rooms and escape routes at risk of a smouldering fire, and heat detectors in kitchens and dusty areas where smoke detectors can cause false alarms. The ESP PSD2 is an optical smoke detector and the ESP FHD2 a heat detector that detects temperatures over 60°C. Multi-sensors such as the Eaton CAPT340 combine smoke and heat sensing to reduce 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 made for security panels, as some smoke and heat detectors are. Texecom Exodus detectors such as the AGB-0001 optical smoke and AGB-0003 heat detectors come in 12V security panel formats, and the range is EN54 BSI Kitemark approved. ESP 12V models include the PSD212 optical smoke, FHD212 fixed heat and RHD212 rate-of-rise detectors.

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 waterproof heat detector with a high IP rating suits wet, condensing or hosed-down areas. The Hochiki DFG-60BLKJ is a conventional 60°C fixed-temperature heat detector rated IP67, approved to EN54-5 with LPCB and VdS certification. It needs no separate mounting base, connecting on short flying leads, and its bi-metallic sensing element keeps standby current low.

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 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.

Yes, if they are plug-in detector heads, which fit onto a base that may be sold separately or supplied with the detector. The ESP MAGPRO-SD1 addressable smoke detector fits the MAGPRO-DB base, which is supplied separately, and the ESP SD-DB deep base allows surface cable entry or mounting on a rough, uneven surface. The ESP CSD212 comes as a combined detector and base.

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.
