Fireclass 516.052.051.YFC MD601Ex Conventional Rate of Rise Heat Detector

Fireclass 516.052.051.YFC MD601Ex Conventional Rate of Rise Heat DetectorThe MD601Ex intrinsically safe detector uses two networked thermistors in a bridge configuration to provide a fast response that depends both on absolute temperature and rate of rise of temperature.This type of sensor reacts to abnormally high rates of change of temperature and provides the fastest response over a wide range of ambient temperatures. A fixed temperature limit is also incorporated in these detectors. In many environments e.g. kitchens and boiler rooms sudden large changes in temperature are considered normal. Rate-of-rise detectors are generally not suitable in these cases and fixed temperature static types should be used.The MD601Ex detectors are designed to comply with EN 50 014 and EN 50 020 for intrinsically safe apparatus and are certified to ATEX Code Ex II 1G and Cenelec Code EEx ia IIC T5.Key FeaturesIntelligent Universal SmokeHeatCO detectorLow profile discreet and unobtrusiveSuperior performance and reliabilityDesigned for fast easy installationOptional locking kitMay be used in systems that meet BS5839 Pt 1Integral and remote alarm LEDCertified to ATEX Ex II 1GD and Cenelec Ex ia IIC T5Ex iaD 20 T100oCComplies to EN54-7 for Smoke Detectors and EN54-5 for Heat Detectors

Ziton ACA-CT-100 Alarmline T Clip - Pack of 100

Ziton ACA-CT-100 Alarmline T Clip - Pack of 100

Ziton ACA-CT-100 Alarmline T Clip - Pack of 100The ACA-CT T clip is designed to secure LHD linear heat detection sensor cable. It may be used as a ceiling or wall mount clip.The clip consists of a low-density polyethylene resin moulding with a slot into which the heat sensing cable is located combined with a 25 mm standoff. In ceiling applications the 25 mm standoff exposes the cable faster to any rise in temperature as it lifts the cable out of the layer of colder air that is often trapped against the ceiling.InstallationThe clip is secured with a screw and wall plug using an M8 pan head screw self-tapping screw. For extra security a tie wrap may be used to prevent the cable from being pulled from the clip. A figure-8 configuration on the tie wrap is ideal for this.Spacing for clips is recommended every meter along the length of the cable. Two clips in close proximity are used at 90 degrees bends or where the cable route changes direction.For space protection applications the ideal location for the heat sensing cable is on the ceiling or the top of the sidewall. This ensures that the cable is rapidly exposed to the plume of hot gases from any event that may arise and spread across the ceiling.Key FeaturesEasy installation of linear heat cableFor ceiling or wall mount applicationsProvides insulation and spacing from walls and ceilingsStandard M4 fixing holePack of 100

Aritech DT992 990 Series Discovery Heat Detector

Aritech DT992 990 Series Discovery Heat Detector

Aritech DT992 990 Series Discovery Heat DetectorThe DT992 is an elegant slim-line addressable heat detector that provides temperature information to the CIE. It uses a single thermistor to sense the air temperature around the detector. With its 5 operating modes it supports 5 classes of temperature detectors as stipulated by EN54.Operating ModesEvery operating mode has a different behaviour each suitable for a different application. All modes have a fixed temperature trigger with optional rate-of-rise selection allowing the detector to respond to a temperature alarm before the fixed level is reached. The DT992 supports A1R 57C with rate-of-rise A2R 61C with rate-of-rise A2S 61C static CR 90C with rate-of-rise and CS 90C static modes of operation.Unique AddressingA unique patented addressing method provides simple user-friendly and accurate identification of device location. A coded card inserted in the base is read by the detector as it is plugged in. All the electronic components are in the detector but the location information is held in the base. Addressing errors during maintenance are eliminated because the address remains in the base. Pre-coded and pre-numbered address cards are available.ApplicationsThe DT992 is ideal for use in environments that are dirty or smoky under normal conditions. It is therefore well suited installation in warehouses loading bays and car parks.Key Features5 Approved response modes for ease of optimisation to different environmentsRejection of transient signalsDrift compensation to ensure constant sensitivity360 Alarm visibilityFlashing LED optionFast alarm reportingEN54 approved and CPR certifiedApollo equivalent 58000-400

Apollo XPander A1R Heat Detector XPA-HT-11170-APO

Apollo XPander A1R Heat Detector XPA-HT-11170-APO

Apollo XPander A1R Heat Detector XPA-HT-11170-APOThere are two heat detectors in the XPander range designed to suit a wide variety of operating conditions. A Static Heat Detector CS which responds only when a fixed temperature has been reached and a Rate-of-Rise Detector A1R which has a fixed upper limit but in addition measures the rate of increase in temperature.OperationHeat detectors have an open-web casing which allows air to flow freely across a thermistor which measures the air temperature every 2 seconds. A microprocessor stores the temperatures and compares them with pre-set values to determine whether a fixed upper limitthe alarm levelhas been reached. In the case of rate-of-rise detectors the microprocessor uses algorithms to determine how fast the temperature is increasing. Static heat detectors respond only when a fixed temperature has been reached. Rate-of-rise detectors have a fixed upper limit but they also measure the rate of increase in temperature. A fire might thus be detected at an earlier stage than with a static detector so that a rate-of-rise detector is to be preferred to a static heat detector unless sharp increases in temperature are part of the normal environment in the area protected by the heat detector.Key FeaturesWireless Can be used in applications where smoke detectors are unsuitableIdeal for environments that are dirty or smoky under normal conditionsCS detectors are ideal for use in environments with rapid temperature fluctuations such as boiler rooms Bi-directional monitored radio platformFive-year battery life using standard AA alkaline batteries

Fireclass 601CH Conventional Enhanced Carbon Monoxide Detector

Fireclass 601CH Conventional Enhanced Carbon Monoxide Detector

Fireclass 601CH Conventional Enhanced Carbon Monoxide DetectorThe 601CH detector forms part of the series 600 range of plug in detectors for ceiling mounting. 601CH have a fast response in fire detection are tolerant in positioning and can be mounted in locations where there are likely to be obstacles to free smoke plume movement. These detectors are particularly well suited to sleeping risk storage areas and applications where smoke detectors are prone to false alarm.Incorporation of A1R rate of rise heat detector within the 601CH provides extra non-selectable detection modes which allows the detectors to operate in a wide variety of applications where combined risk mean that CO detection alone would be insufficient. The integrated rate of rise detector acts as a normal heat detector additionally enhancing the sensitivity of the carbon monoxide detector if a rapid change of temperature is detected by the detector thermistor.Key FeaturesLow profile discreet and unobtrusiveSuperior performance and reliabilityDesigned for fast easy installationIntegral and remote alarm LEDSeries of product approvals
