Morley IAS MI-DISO Loop Isolation Module

Morley IAS MI-DISO Loop Isolation Module

Morley IAS MI-DISO Loop Isolation ModuleThe Morley-IAS loop isolator module is used on the Morley-IAS intelligent fire alarm control panels to protect the system against wire-to-wire short circuits on the analogue addressable loop wiring. The fault isolator modules should be placed between groups of sensors on the loop wiring to protect the loop if a short circuit fault occurs.If a short circuit fault occurs the two isolators located either side of the short circuit fault will automatically sense the voltage drop open their switches and remove the devices from the rest of the loop. If the line voltage then rises above a fixed threshold indicating that the short circuit fault is removed then the isolator module will automatically restore the power to the isolated group of devices.The MI-DISO isolator uses a unique mechanical design allowing each module to be mounted either in a wall box or on a DIN rail. Irrespective of the mounting method chosen the address switch is both visible and accessible for selection. To help engineers in the maintenance and fault-finding process both the LEDs and the address switches can be viewed without having to remove the cover of the mounting box. The LEDs being multi-colour provide diagnostic information regarding the status of the isolator.Key FeaturesDIN rail mounting optionSurface mounting optionPlug in connectorsTri-colour LED status indicationAddress selector switches visible in 2 planesLED status visible in 2 planesApproved to GEA GEI 1-082 and CEA GEI 1-084

Apollo Series 65 Optical Smoke Detector with Flashing LED and Magnetic Test Switch 55000-315APO

Apollo Series 65 Optical Smoke Detector with Flashing LED and Magnetic Test Switch 55000-315APO

Apollo Series 65 Optical Smoke Detector with Flashing LED and Magnetic Test Switch 55000-315APOThe Series 65 Optical Smoke Detector incorporates a pulsing LED located within the housing of the detector. The external detector moulding is identical to that of the ionisation detector and has an indicator LED which is clear in quiescent state but produces a red light in alarm.OperationThe Series 65 Optical Smoke Detector has a moulded self-extinguishing white polycarbonate case with wind resistant smoke inlets. Nickel-plated stainless-steel wiper contacts connect the detector to the base. Inside the case a printed circuit board has the optical system mounted on one side and the signal processing electronics on the other. The sensing chamber is a black moulding configured as a labyrinth which prevents penetration of ambient light. The labyrinth has a fine gauze insect-resistant cover. The chamber houses an infrared light emitting diode LED and a photo-diode which has an integral visible-light filter as extra protection against ambient light. Every three seconds the LED emits a burst of collimated light modulated at 4kHz. In clear air light from the LED does not fall directly on the diode because the LED is positioned at an obtuse angle to the diode. When smoke enters the chamber a fraction of the collimated light is scattered onto the photo-diode. If the resulting signal from the photo-diode is above a pre-set threshold the LED emits two more bursts of light this time at two-second intervals. If light is scattered onto the photo-diode by both these pulses due to the presence of smoke the detector signals an alarm state by switching the alarm latch on increasing the current drawn from the supply from about 40A to a maximum of 75mA. This fall in the impedance of the detector is recognised by the control panel as an alarm signal. The alarm current also illuminates the detector integral LED. A remote indicator connected between the L1 IN terminal and the R terminal will have a voltage equal to the supply voltage less 1 volt across it and so will illuminate. To ensure correct operation of the detector the control panel must be arranged to supply a maximum of 33 Volts dc and a minimum of 9 Volts dc in normal operation. The supply may fall to 6 Volts dc in alarm conditions if a supply current of at least 10mA is available at this voltage. To ensure effective illumination of the integral LED and any remote indicator the supply to the detector should exceed 12 Volts. To restore the detector to quiescent condition it is necessary to expel any smoke and interrupt the electrical supply to the detector for a minimum of one second.Key FeaturesResponds well to slow-burning smouldering firesWell-suited to bedrooms and escape routesUnaffected by wind or atmospheric pressureFlashing LED and magnet operated test switch option

Apollo XP95 Multisensor Detector 55000-885APO

Apollo XP95 Multisensor Detector 55000-885APO

Apollo XP95 Multisensor Detector 55000-885APOThe XP95 multisensor Detector contains an optical smoke sensor and a thermistor temperature sensor whose outputs are combined to give the final analogue value.The multisensor construction is similar to that of the optical detector but uses a different lid and optical mouldings to accommodate the thermistor temperature sensor. The sectional view shows the arrangement of the optical chamber and thermistor.The signals from the optical smoke sensing element and the temperature sensor are independent and represent the smoke level and the air temperature respectively in the vicinity of the detector.The detectors microcontroller processes the two signals.The temperature signal processing extracts only rate of rise information for combination with the optical signal. The detector will not respond to a slow temperature increase - even if the temperature reaches a high level. A large sudden change in temperature can however cause an alarm without the presence of smoke if sustained for 20 seconds.The processing algorithms in the multisensor incorporate drift compensation. The control panel must not have a drift compensation algorithm enabled. The sensitivity of the detector is considered the optimum for most general applications since it offers good response to both smouldering and flaming fires.Key FeaturesSensitive to a wide range of firesWell suited for environments such as hotel bedroomsUnaffected by wind or atmospheric pressureOther part codes include AD-2004

Smoke Sabre Hand Held Smoke Detector Tester 150ml

Smoke Sabre Hand Held Smoke Detector Tester 150ml

Smoke Sabre Hand Held Smoke Detector Tester 150mlSmoke Sabre is a major step forward in the design of smoke detector testers. All other pressurized aerosol smoke alarm testers have the inherent drawback that if misused they leave harmful residue on the casing and or inside the chamber of the detector.This residue can discolour the detector plastic can attract dust affect sensitivity and in some cases lead to corrosion cracking or even complete failure of the detector. Residue occurs when testing aerosols are used too close to the detector or smoke alarm despite instructions not to do so. SmokeSabre cannot be used too close to the detector and eliminates harmful residue while focusing and targeting the canned smoke test gas. When SmokeSabre is in the closed position the sabre prevents access to the spray button.The aerosol can only be activated when the sabre is fully extended. In use air is drawn through the holes in the sabre and this coupled with the venturi effect involved assists the velocity and vaporization process of the airborne smoke particles. The result is a more effective test delivering better detector activation using less gas per test and reducing costs while eliminating harmful residue.Key FeaturesMore tests per canFaster detector activation and clearingLowest cost per testThe end of harmful residue risk is designed out with the sabreSilicone free testingEco-responsibility 100 bio-degradable sabre ozone friendly no CFCs and low GWPDetector manufacturer endorsementUL and ULC listed150ml can
