Apollo Fire ORB-HT-11004-APO temperature sensor, White

Please note: this is a non-returnable item (excluding faulty goods)

Apollo Fire ORB-HT-11004-APO is a temperature sensor from the Orbis range.

Brand Information

Orbis is a range with modern styling and a mounting base that saves installation time. It is electrically compatible with Apollo Series 65 and previous ranges of conventional detector. Orbis is a demonstration of Apollo's commitment to the market for high quality conventional detectors for use in small to medium size installations.

In developing this range Apollo has put ease of installation and reliability in daily operation at the forefront of considerations. The attractive and compact design means that Orbis will blend in well with all architectural styles. Orbis is manufactured in Apollo's factory near Portsmouth, England

Orbis has been tested and approved to the following standards: EN54-7: 2000 + A1: 2002 optical smoke detector

EN 54-7: 2000 + A1: 2002 & CEA 4021: 2003-07

multisensor smoke detector EN 54-5: 2000 + A1: 2002 heat detector

Detectors have been declared as being compliant with the essential requirements of the EMC Directive 2004/108/EEC and the Construction Products Directive 89/106/EEC

• Operation

Orbis heat 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 limit-the alarm level-has 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 also 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 of heat are part of the normal environment in the area protected by the heat detector.

Maintenance & Service

Detectors should be checked regularly at the intervals indicated by the locally applicable code of practice. Apollo recommends that detectors be checked at least once a year. One of the features of Orbis is FasTest® which makes it possible to carry out a functional test, using smoke or heat, within about four seconds.

If detectors appear not to be functioning correctly they should be returned to Apollo for testing. If detectors are externally dirty they can be cleaned carefully with a damp cloth sing a small amount of industrial alcohol. DirtAlert™

Orbis detectors have drift compensation to compensate for changes caused by the environment. The most usual change is contamination.

Key features

• Can be used for applications where smoke detectors are unsuitable
• Ideal in environments that are dirty or smoky under normal conditions
• Red flashing LED at StartUp confirms the device is operating
• SensAlert, yellow flashing LED indicates faulty operation
