Table detailing the loop standby and alarm load for typical 
Algo-tec™ 6000 devices.
Note: The following Loop Parameters should be observed
1) The total number of addressable devices should not exceed 191 per loop.
2) Add 20mA to total loop alarm load to allow for fire indicator LED’s on devices
3) The total loop alarm load should not exceed 600mA per loop.
* Auxiliary 24V dc supply required.
