814I IONISATION SMOKE DETECTOR

3.8.1GENERAL

The 814I is an ionisation smoke detector. The detector senses the amount of smoke present and sends this value to the MXP. The MXP makes any decisions as to whether this is an alarm, fault, normal or whatever. The integral LED is turned on by the MXP when an alarm is detected.

The remote LED and functional base outputs are programmable for their functionality (refer to section 3.3).

3.8.3MX4428 PROGRAMMING OPTIONS - 814I

The programmable values for the 814I are explained in the following table.

Normally only the mode needs to be programmed, and then only if a functional base or remote LED is required and its operation is different from the default. Refer to section 3.3.

In some cases the alarm sensitivity (Parameter 1) may need to be changed from the default. The approved range for Australia is 0.22 MIC X (23) to 0.39 MIC X ( 66). The available range is 0.22 MIC X (23) to 0.59 MIC X (130). If the alarm sensitivity is changed, the pre-alarm sensitivity (Parameter 0) should normally be changed to about 75% of the alarm sensitivity.

The remaining parameters should not need changing.
