Carrier 5150-W 2-Wire On-The-Glass Piezo Sensor With 30 cm Wire Leads NC Alarm OutputThe Sentrol 5150 series glass break detector has been designed using the latest electronic techniques. This enables the detector to contain all the necessary circuitry for excellent detection whilst filtering out and rejecting all unwanted signals that would normally result in a nuisance alarms e.g. ultra-sound radio frequency interference etc. The 5150 series will provide a 3 m radius of protection. Suitable for use on standard window glass plate wired tempered and laminated glass.Due to the design of the product the detector may be fitted as close as 2.5 cm from the window frame and still provide a full 3 m radius. The 5150 series detectors are passive sensors therefore any number of detectors may be installed on the same windowpane without the risk of interaction. The detectors use a fail-safe normally closed open to alarm relay contact enabling compatibility with any standard burglar alarm control equipment.The output from the relay contact should be connected via the alarm 24-hour tamper loop in order to provide early signalling at the control whether the alarm is switched on or off. The opening of the normally closed relay contact signals the alarm.Easily installs with pre-cut specially formulated 3M adhesive tape.Key Features3 m radius of coverage measured from the sensorProtects all glass types up to a standard thickness of 6.4 mm includingplate wired tempered and laminated glassIdeal for 24-hours loop protectionTwo wire sensor drawing no power from the loopCompatible with most wireless transmitters

Apollo Series 65 Optical Smoke Detector with Flashing LED 55000-316APO

Apollo Series 65 Optical Smoke Detector with Flashing LED 55000-316APO

Apollo Series 65 Optical Smoke Detector with Flashing LED 55000-316APOThe 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

Pleasenote This product incurs additional shipping charges.Hawco 312-300 12 14 NPT Female Hexagonal RetainingNut for Detect-A-Fire Heat Detectors Pack of 6DETECT-A-FIRE D-A-F detectors are the heartof many fire protection systems. The highly reliable D-A-F has been thestandard for over 75 years. The D-A-F is used for signaling overheat or fireconditions. In most applications the D-A-F provides the initial heat sensingthat is used to activate suppression systems using clean agent CO2 inertgases wet or dry chemicals or water.D-A-F detectors are widely accepted because they aredesigned with rate compensation. This provides a unique advantage over bothfixed temperature and rate-of-rise types of detectors because the D-A-Fdetector accurately senses the surrounding air temperature regardless of thefire growth rate. At the pre-determined set point the system is activated.Fixed temperature detectors must be completely heated to alarm temperature andtherefore a lag in response time may occur with a fast rate fire. Rate-of-risedevices on the other hand are triggered by the rate of increase in ambienttemperature and are subject to false alarms caused by harmless transientthermal gradients such as the rush of warm air from process ovens. The key to the detectors sensitivity is in the design. Theouter shell is made of a rapidly expanding alloy which closely follows changesin surrounding air temperature. The inner struts are made of a slower expandingalloy. Designed to resist thermal energy absorption and sealed inside theshell the struts follow temperature changes more slowly. A slow rate fire willheat the shell and struts together. At the set point the detectorwill trigger actuating the alarm or releasing the extinguishant.A transient rush of warm air up to 40Fmin. mayexpand the shell while not triggering the detector. By ignoring transient warmair excursions the D-A-F detector virtually eliminates false alarms prevalentwith rate-of-rise devices. If a fast rate fire starts the shell will expandrapidly. The struts will close actuating the alarm andor releasing the agent.The faster the fire rate of growth the sooner the D-A-F detector will react.
