Loop Card
Typical SENTRI4 System
The loop allows wiring of addressable devices like re sensors, alarm sounders, call
points, interface units, mimic and repeat panels, a combined maximum of up to
200 devices are allowed per loop circuit, a further limit on a loop circuit is determined
by device loading.
