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

Apollo Discovery Carbon Monoxide CO Detector 58000-300APO

Apollo Discovery Carbon Monoxide CO Detector 58000-300APODiscovery CO fire detectors contain a long-life electro-chemical carbon monoxide sensor which is tolerant of low levels of common vapours and household products. The sensing technology is fast accurate and needs only very low power. The detection capabilities are enhanced by a rate-sensitive response. Fast rises in the carbon monoxide level are often associated with hot fires and the detector will respond earlier under these conditions. The analogue reply from the detector is rate limited to remove nuisance alarms resulting from short-term high levels caused by sources such as pipe smokers or gas flame ignition.Brand InformationDiscovery is a range of high-specification analogue addressable fire detectors and alarm devices. Discovery detectors offer effective false alarm management by a combination of EN 54 approved operating modes and sophisticated algorithms. Drift compensation further reduces the likelihood of false alarms caused by a build-up of dust in the sensing chamber. In addition to the familiar smoke and heat detectors the Discovery range features two multisensor detectors. One is an opticalheat multisensor which can be used to protect against many types of fire risk. The other is a carbon monoxideheat multisensor which protects against both smouldering fires and those generating heat.OperationThe Discovery CO detector has five operating modes each having a set combination of sensitivity and response delay which the user can select for any given application.ApplicationCO detectors do not detect smoke particles or heat and are not universal replacements for smoke detectors. Apollo does not endorse the use of CO detectors as the main method of fire detection if the protected area is an escape route there is a requirement to detect overheating of electrical equipment or cables the protected area is exposed to sources of CO such as vehicle exhausts or to hydrogen or to high levels of alcohol vapour as emitted by some cleaning agents there is a requirement to detect fires involving flammable liquids CO fire detectors are particularly suitable for supplementing smoke detection when there is a deep seated smouldering fire risk a risk of fire starting in an enclosed space a likelihood of stratification taking place Carbon monoxide detectors may be used as the primary fire detector in areas where the following conditions exist the main risk is smouldering fires optical smoke detectors are deemed unsuitable see FALSE ALARMS below the fire compartment is not greater than 50m2 Typical applications include hotel bedrooms halls of residence sheltered accommodation and hospital wards.CommunicationDiscovery uses a digital communications protocol which has been developed from the XP95 protocol but differs in that it allows communication in three different modes Normal Read and Write to allow a more extensive exchange of information and commands than previous analogue addressable ranges. In addition Discovery can store data in non-volatile memory. The Normal mode is identical to the XP95 protocol with the exception that the five additional analogue value bits in the XP95 protocol extension have been re-defined so that the fire control panel is able to distinguish between Discovery and XP95 devices. The Read mode is used to check information stored in the non-volatile memory of each detector. It is accessed by using a simple extension to the Normal mode communication method from the fire control panel to the detector. In Write mode the fire control panel is able to write information to the detector by extending the communication method in the same way as in Read mode. During Read or Write modes a detector can signal an alarm by means of the alarm flag and alarm address bits. Discovery detectors are compatible with XP95 and Soteria. It should be noted however that Discovery features will not be available when Discovery is used with XP95 fire control panels. Fire control panels with drift compensation algorithms should disable the algorithms when communicating with Discovery. For fire control panels running CoreProtocol please refer to the fire control panel manufacturers operating instructions.

The range also includes products such as beacons to help meet the requirements of the Disability Discrimination Act DDA.Brand FeaturesAlarmSense sounders and manual call points are fitted to the same zone as detectors. In quiescent state the zone is powered at between 9V and 15V nominally 12V at which only detectors and call points operate. Sounders require 24V to operate.When an alarm is detected on a zone the control panel increases the line voltage to 24V on that zone causing the sounders to produce a continuous Evacuate sound. Any voltage-sensitive output devices - relay modules or other alarm devices - also operate.When the voltage is increased to 24V the detector alarm current will reduce to 1.5mA. The detectors are latched in alarm until they are reset by reducing the voltage to less than 2V for greater than 1 second. Output devices will de-activate each time the voltage is reduced to 12V unless otherwise stated in their specification.It is possible to generate an Alert tone by pulsing the supply voltage from 12V to 24V and the sounders configured to continuous output.
