Apollo Discovery Cat O. Discovery Sounder VAD Base with Isolator 45681-700APO

Apollo Discovery Cat O. Discovery Sounder VAD Base with Isolator 45681-700APOThe Discovery Sounder VAD Base makes full use of the Discovery protocol. For ease of commissioning a Magnetic Wand can be used to test and adjust each sounder VAD locally.Key FeaturesEN54-23 certifiedFlash rate of 0.5HzIt is possible to set individual volume of the sounder from the panel15 pairs of tones including IMO code 1A General Emergency Alarm and IMO Code 2 All ClearBuilt in isolatorBrand 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 Multisensor construction is similar to that of the optical detector but uses a different lid and optical mouldings to accommodate the thermistor heat sensor. The Discovery OpticalHeat Multisensor Detector contains an optical smoke sensor and a thermistor temperature sensor whose outputs are combined to give the final analogue value. The way in which the signals from the two sensors are combined depends on the response mode selected.The five modes provide response behaviour which incorporates pure heat detection pure smoke detection and a combination of both. The multisensor is therefore useful over the widest range of applications. 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 micro-controller processes the two signals according to the mode selected. When the detector is operating as a multisensor the temperature signal processing extracts only rate-of-rise information for combination with the optical signal. In these modes 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.

Nittan EV-PYH-SCI Photoelectric Optical amp Heat Cat P Multi-Sensor With Short Circuit Isolator

Nittan EV-PYH-SCI Photoelectric Optical amp Heat Cat P Multi-Sensor With Short Circuit Isolator

Nittan EV-PYH-SCI Photoelectric Optical Heat Cat PMulti-Sensor With Short Circuit IsolatorEV-PYH-SCI is an Optical Smoke Heat Category PMulti-sensor Detector with integral Short Circuit Isolator fully compatiblewith Evolution analogue addressable systems.The EV-PYH-SCI comes to the market with some exciting newtechnological advances centred on an enhanced new PY smoke sensing chamber.The sensor includes a spherical feature within the smoke chamber providingunrivalled performance for scattering light plus an Orange LED whichsignificantly improves response across the fire spectrum. The Chamberconstruction is designed to minimise the effect of dirtdust contamination witha fine micromesh made of stainless steel to prevent ingress of even thesmallest insects which can create false alarms.This advanced Multi Sensor is able to combine the benefitsof both optical and heat sensing technologies making it less prone to falsealarms than individual sensing devices. An innovative Nittan designed algorithmreads both signals simultaneously and generates alarm signals from either orboth sensors. The Heat sensor is Category P meaning it can be configured aseither A1R A2S BS or CS heat category.The integral Short Circuit Isolator is bi-directional and inthe event of an external fault will shut down on one side to protect thesystem whilst allowing the device to continue communication with the firealarm control panel from the opposite side. The isolator will self-reset whenthe fault is cleared.The Nittan UB-6-SL-EV Base includes a sliding link toprovide loop continuity when detectors are removed. This is to ensure CallPoint operation is not affected by detector removal in accordance with BS5839-1 Clause 12.2.2.Key FeaturesOrange Optic LED and PY Type Chamber5 Sensitivity SettingsHeat Category P A1RA2SBSCSIntegral -ve Short Circuit IsolatorDrift compensationEvolution FSK protocolEEPROM Addressed with programmer
