Description

The Apollo Orbis Marine A1R ORB-HT-41013-MAR is a heat detector, suitable for a wide range of operating conditions in which smoke detector are unsuitable.

The Apollo ORB-HT-41013-MAR has an open-web casing which enables the air to flow freely across a thermistor which measures the air temperature every 2 seconds. A microprocessor stores the temperature and compares them with pre-set values to determine if the alarm leven has been reached.

The Apollo ORB-HT-41013-MAR is used in applications where smoke detectors can not be used. Smoke detectors are used whenever possible, since smoke detectors provides an earlier warning of fire than a heat detector. Heat detectors should only be used when there is a danger of nuisance alarms from smoke detectors.
