+ | This driver manages a pulse-operated latch, such as the Southco R4-EM or similar. | ||
+ | == Features == | ||
+ | * Monitor latch and door status | ||
+ | * Control latch 100 ms pulse | ||
+ | * Detects latch and door tamper | ||
+ | * Re-trigger latch if door is opened and latch is reset | ||
+ | * Monitor and report total time door was opened | ||
+ | * Optionally report if door is open longer than allowed | ||
+ | |||
+ | The driver expects the following connections: | ||
+ | ^ Type ^ Signal ^ Purpose ^ Status ^ | ||
+ | | Input | Door status | Monitor the status of the door | Closed circuit = Door closed | | ||
+ | | Input | Latch status | Monitor the status of the latch | Closed circuit = Latch closed | | ||
+ | | Output | Latch trigger | Triggers the latch to open | 100ms positive pulse | | ||
+ | |||
+ | Note that the output pulse voltage is the same as the system supply voltage. | ||
+ | |||
+ | The Latch should be supplied directly from the power supply. | ||
+ | DO NOT supply the latch through the ezeio. | ||
+ | |||
+ | The following events are detected and logged/ | ||
+ | ^ Condition ^ Reported status ^ | ||
+ | | Latch triggered & door opened | "Door opened" | ||
