Fireclass DPK6 Duct Probe with 4B-C 4quot Continuity Base

Fireclass DPK6 Duct Probe with 4B-C 4quot Continuity Base

Fireclass DPK6 Duct Probe with 4B-C 4 Continuity BaseThe DPK6 duct probe units have been developed to detect smoke in ventilation ducts and offer significant benefits in terms of performance and installation. For most applications smoke or combustion products are likely to have travelled some distance ageing the smoke prior to reaching the probe unit. It is therefore normally recommended that an optical smoke detector be fitted and this is often a requirement of building regulations. The DPK6 duct probe units use FC460PH Multi Sensor Smoke Detectors.The DPK6 Duct Probe units are not normally mounted directly inside ducts because the airflow only allows the detector to sample air from a small section of the duct and such detectors would rapidly become dirty. Instead ducting is protected by the use of probe units which gather air from a cross section of the duct and pass it through a smoke detector head.The system comprises only one single duct probe tube which improves efficiency and reduces installation time. The DPK6 duct smoke detector housing is designed to comply with the stringent demands of new European standard EN 54-27. The system fulfils all the requirements for safe fire detection with airflow speeds from 15 ms to 20 ms. For the airflow through the adaptor to be representative of the airflow in the ventilation duct the detector should be installed at a place where normally flow meters etc. are sited.Key FeaturesDPK6 for use with FC460PH with built-in 4B-C 4 continuity base.Designed to comply with EN 54-27.One-pipe air sampling system.Patented Cap-up Venturi pipe and duct housing.Test hole on cover.Simple installation.Sensitive flow indicator.Simple service and maintenance.Range of aluminium probe tubes are available for ducts up to 2700 mm.

Apollo XP95 I.S. Heat Detector 55000-440APO

Apollo XP95 I.S. Heat Detector 55000-440APO

Please note This product is currently on an extended leadtime. We estimate that the product will be available with full approvals from February 2025. For further information please read the manufacturerslatest technical bulletin.Apollo XP95 I.S. Heat Detector 55000-440APOThe XP95 IS Heat Detector is distinguishable from XP95 IS smoke detectors by its low air-flow resistance case which allows good contact between the sensing thermistor and the surrounding air. The device monitors temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature.The voltage signal is processed and transmitted to the control equipment in the same way as in the case of the ionisation smoke detector. Full details of the principles of operation and the electrical description are published in the XP95 Engineering Product Guide. XP95 IS detectors have the same operating characteristics as the standard versions.Brand InformationXP95 Intrinsically Safe IS detectors are a development of the well-established analogue addressable XP95 range from Apollo. XP95 IS detectors feature all the benefits of the standard range but are developed specifically for use in hazardous areas. The addresses of XP95 IS detectors are set by means of the patented XPERT card.Key FeaturesRate of rise and fixed temperature alarm point.Single thermistor technology.Transient voltage protection.Resettable operation.Lockable security fitting.Please Note Must be connected to a suitable safety barrier and protocol translator

Advanced MxPro MXP-542 24VDC - 24VDC Convertor Isolator

Advanced MxPro MXP-542 24VDC - 24VDC Convertor Isolator

Advanced MxPro MXP-542 24VDC - 24VDC Convertor IsolatorA 24VDC - 24VDC Convertor Isolator for use with Mxp-631 Fib.The Mxp-631 media converters are equipped with a multiple interface circuit that can handle RS-232 or RS-422485 serial interfaces and multi-mode or single-mode fiber. Mxp-631 converters are used to extend serial transmission up to 5km Mxp-631-MM with multi-mode fiber or up to 40km Mxp-631-SM with single-mode fiber. The Mxp-631 converters can be configured to convert either RS-232 signals or RS422485 signals but not both at the same time.The Mxp-631 converters can automatically detect the serial baudrate. This is an extremely convenient feature. Even if a devices baudrate is changed the signal will still be transmitted through the media converter without any data loss.The Mxp-631 converters can be used to connect serial devices to a fiber ring. To form the ring connect to the Tx port of one Mxp-631 to the Rx port of a neighbouring converter. Once the ring is set up simply use the DIP switches to configure the Mxp-631 converters for ring mode. When one node transmits a signal the signal travels around the ring until it returns back to the transmitting unit which then blocks the signal. With the Mxp-631 you can set up fiber rings that have a total circumference of up to 100km.ADDC is a patented hardware data flow solution to handle RS-485 data direction control. ADDC senses and controls RS-485 data direction automatically making it unnecessary to use the hand shaking signal.Key FeaturesExtends RS-232422485 transmission up to40 km with single-mode - Mxp-631-SM5 km with multi-mode - Mxp-631-MMCompact sizeProtects against electrical interference and chemical corrosionSupports baudrates of 50 bps to 921.6 KbpsWide temperature models available -40 to 75CPlease note this way of communication is not EN54 approved.
