Description
The D-9107REXD uses its two pyroelectric infrared sensors to differentiate the change of light caused by a flame from any background signals. The two sensors process two distinct frequencies of the infrared spectrum through individual processing channels, allowing the detector to make a reliable alarm decision.
The D-9107REXD may be used in explosive Zone 1 and 2, as well as Zone 21 and 22 flammable dust environments.
It may be connected directly on to a GST addressable fire alarm loop, or be used in any standard conventional system where it provides potential free contacts for both fire and fault conditions. |
