The panel can provide up to 280mA of current to the devices on the loop at normal standby.
For device currents see Appendix F - Battery Calculations on page 76.
For further information refer to the device Installation Instructions and other documentation
provided with the addressable devices, bases, and isolators.
5.1.4 Drift Compensation
Drift Compensation is built into AP devices and CLIP devices Models MRI-2251TMB and MRI-
7251B, and is not performed by the panel. Drift Compensation is not provided for other CLIP
devices.
Drift compensation automatically adjusts for gradually increasing effects of dust and other
accumulations of dirt in the detectors. It will adjust the thresholds to compensate for a detector
going dirty according to the gradual change in the normal clean air value received. When it can
no longer compensate for an increasingly dirty detector, a dirty detector trouble is indicated for
that device.
5.1.5 Auto Test
Periodically each detector is commanded to return an alarm value to test its ability to alarm. If
the device fails the test, a trouble is indicated on that device. This trouble is latched until
system reset.

Configurable Input Types
Input devices and modules may be configured as one of many possible input types. Table 12
identifies the device types assignable to each input type. For device type descriptions see
sections 5.2.1 to 5.2.12.
