Apollo Intelligent Auto-Aligning Beam Detector SA7100-100APO

Apollo Intelligent Auto-Aligning Beam Detector SA7100-100APOThe Intelligent Auto-Aligning Beam Detector combines a transmitterreceiver in the same detector head with an automatic alignment motor. This combination with integrated addressability allows for quick and simple installation. The Intelligent Auto-Aligning Beam Detector automatically compensates for environmental effects on the beam signal keeping the unit in the best possible working order. This is achieved through the combination of software automatic gain control and motorised realignment of the beam.OperationThe Intelligent Auto-Aligning Beam Detector is a compact detector for detecting smoke in large open areas such as warehouses theatres churches and sports centres. It comprises a ground level loop-powered controller a detector head with an operating range of 8m-50m and a single prism. The operating range of each detector head can be increased up to 100m by using the Extension Kit which comprises of three additional prisms.An additional detector head can be connected to the controller. Each head has a loop address. It also has a built in 20T negative bi-directional short circuit isolator and it is compatible with control panels using CoreProtocol Discovery and XP95 protocol. A built-in laser provides rapid initial alignment and thereafter the detector head will continuously automatically align and compensate for any building movement.The status of each detector can be monitored through the controller which is sited at ground level. The detector head operates both as a transmitter and a receiver. A well-defined IR beam is projected to a prism mounted on the opposite wall which is reflected back to the receiver. In the event of smoke partially obscuring the light an imbalance between the transmitted and received light will occur. The detector will then transmit an alarm value to the control panel.The detector is factory set to a beam obscuration of 35 which is the best setting for most factories and warehouses. The setting can be changed to 25 for offices and clean areas such as theatres or to 50 for hostile areas such as mills or foundries. The detector reports a pre-alarm analogue value 48 at approximately 75 of the alarm threshold. The detector compensates automatically for gradual contamination of the lenses in order to avoid false alarms. The detector is non-latching and resets 30 seconds after an alarm event ceases and in 3 seconds after the removal of a fault.Key FeaturesLoop Powered and compatible with XP95 Discovery and CoreProtocolIncorporates a bi directional short-circuit isolatorAutomatic drift compensationAutomatic resetGround level ControllerAutomatic alignment compensation for building movementLaser assisted alignment for quick installationAllows for 2 detector heads per controllerUp to 100m rangePre-alarm thresholdEN 54-12 and EN 54-17 certified

Apollo 45681-330APO Intelligent Sounder Visual Indicator Base with Isolator

Apollo 45681-330APO Intelligent Sounder Visual Indicator Base with IsolatorThe low volume range is useful in areas such as hospitals where a fire alert is initially intended to warn staff only. The sounder is set to the high range for general use. Synchronisation of tones ensures the integrity of the signaltones from different sounders do not merge into one signal that could be mistaken for a different tone. Group addressing is a simple method of alerting an entire area or group of rooms without delay.For systems requiring isolators at every point the built-in isolator saves installation time and cost. The acoustic self-test means that the sounder listens to itself when it is switched on. If no sound is detected a fault signal is transmitted when the sounder is polled.The beacon self-test is achieved by means of an LED monitoring circuit. If the LEDs do not draw current when the sounder beacon base has been switched on a fault signal is transmitted when the device is next polled.Key FeaturesTwo volume ranges 55-75dBA and 75-91dBAVisual indicator flash rate of once per secondSynchronisation of alert and evacuate tonesSynchronisation of visual indicator flashIndividual and group addressingUnique acoustic and visual indicator self-testBuilt-in Isolator

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
