Fire Protection System (FPS) is an authorised Apollo distributor in Bhopal, supplying Apollo conventional detectors from the Series 65, Orbis and AlarmSense ranges: optical smoke detectors, heat detectors in several EN 54-5 classes, an Orbis multi-sensor and an intrinsically safe Orbis optical detector. They work with conventional zone panels, and FPS installs, tests and maintains them across Madhya Pradesh.
A conventional optical smoke detector that senses smoke in its chevron chamber by photo-electric light scattering and responds well to slow burning, smouldering fires. It comes in a standard and a flashing LED version, and its LED is clear in normal state and lights red in alarm.
A conventional heat detector that monitors temperature with a dual thermistor network, classed A1R to EN 54-5: the lowest temperature band, with rate of rise response. It suits places where smoke detectors are unsuitable, such as dirty, smoky or steamy areas.
A conventional heat detector in class BR, for areas that run warmer than a normal room, with rate of rise response. Its dual thermistor network gives a voltage output that follows the surrounding air temperature.
A conventional heat detector in class CR, for areas with higher normal temperatures, that also responds to a fast rise in temperature. Its dual thermistor network gives an output that follows the surrounding air temperature.
A conventional heat detector in class CS, which responds at a fixed temperature in the higher C band rather than to a rate of rise. Its dual thermistor network follows the surrounding air temperature.
A conventional optical smoke detector using the light scatter principle, with sensing technology designed to reduce false alarms. It responds well to slow burning, smouldering fires.
A conventional detector that combines optical smoke and heat sensing: good for general use and more sensitive than an optical detector to fast burning, flaming fires, including liquid fires. Apollo recommends it where heat is likely early in a fire.
An Orbis conventional heat detector in class A1R: the lowest temperature band, with rate of rise response. A single thermistor gives an output that follows the air temperature, for areas where smoke detectors are unsuitable.
An Orbis conventional heat detector in class A2S, which responds at a fixed temperature in the A2 band without rate of rise response. A single thermistor follows the surrounding air temperature.
An Orbis conventional heat detector in class BR, for areas warmer than a normal room, with rate of rise response. A single thermistor follows the surrounding air temperature.
An Orbis conventional heat detector in class CR, for areas that run hot in normal use, with rate of rise response. A single thermistor follows the surrounding air temperature.
An Orbis conventional heat detector in class CS, which responds at a fixed temperature in the higher C band. A single thermistor follows the surrounding air temperature.
An intrinsically safe conventional optical smoke detector for hazardous areas such as refineries and offshore platforms. It works on the light scatter principle and suits places where slow burning or smouldering fires are likely.
An AlarmSense conventional optical smoke detector that goes into alarm when smoke in its chamber reaches a preset level. It is certified to EN 54-7 and aimed at residential applications.
An AlarmSense conventional heat detector with a fixed upper temperature limit that also measures how fast the temperature is rising. It is used where smoke detectors are unsuitable, such as dirty or smoky areas.
Conventional detectors are wired to a conventional fire panel in zones: the panel shows which zone is in alarm rather than which single detector. Apollo offers three conventional ranges here, Series 65, Orbis and AlarmSense, and each detector plugs into the base made for its own range, so choose the range first and keep to it across the site.
Then choose by the fire you expect. Optical smoke detectors use light scattering: smoke entering the chamber scatters light onto a sensor, so they respond well to slow burning, smouldering fires and suit bedrooms and escape routes. Heat detectors are for places where a smoke detector would be unsuitable, such as areas that are dirty, smoky or steamy in normal use. The Orbis Multi-Sensor combines optical and heat sensing and is more sensitive than an optical detector to fast burning, flaming fires, including liquid fires.
For heat detectors, pick the EN 54-5 class. The letter and number (A1, A2, B, C) set the temperature band the detector is built for, from A1 for normal room temperatures up to C for areas that run hotter in normal use. An R suffix means it also responds to a fast rise in temperature, and S means it responds only at its fixed temperature. Series 65 heat detectors come in A1R, BR, CR and CS, Orbis in A1R, A2S, BR, CR and CS, and AlarmSense in A1R.
For hazardous areas such as refineries and offshore platforms, the Orbis I.S. Optical Smoke Detector is intrinsically safe and carries approvals including IECEx, BASEEFA and PESO (CCoE). On Orbis detectors, FasTest checks a detector in four seconds and DirtAlert flashes a yellow LED when a detector is dirty. FPS supplies, installs and maintains all of these in Bhopal and across Madhya Pradesh.
