Block diagrams - SmartRelay 3 system
All calculations and thus cable type recommendations refer to a voltage supply of 12 V.
Currentless open closing (failsafe) with fire alarm system, push-button and reader
The used locking device opens when it is disconnected from the power. In the normal state the contacts of the fire alarm system are connected to each other and the relay contacts of the SmartRelay are also connected to each other. The current can flow from the power supply unit through the locking device, through the contacts of the fire alarm system and the relay contacts of the SmartRelay. The locking device remains closed.
If the circuit of the locking device is interrupted, the locking device opens. Possible causes:
- An authorised identification device is activated on the reader. The relay contact of the SmartRelay opens.
- The button is actuated. The relay contact of the SmartRelay opens.
- The fire alarm system detects a fire. The contacts of the fire alarm system are no longer connected.
- The power fails (for example due to a fire).
- A remote opening of the SmartRelay is performed.
You can use the following cable types under the following conditions. (For detailed wiring information, see Information on cabling).
Number | Framework conditions | Cable type |
|---|---|---|
1 | Cable length power supply unit to controller ≤ 15 m (15 m outward and 15 m return) | F-YAY 2x2x0.6 |
2 | Cable length controller to reader (or controller to button) ≤ 15 m (15 m outward and 15 m return) | CAT5, shielded |

Currentless closed closing (fail-secure) with button and reader
The used locking device opens when it is supplied with power. Normally the relay contacts of the SmartRelay are not interconnected. Current cannot flow from the power supply through the SmartRelay relay contacts to the locking device. The locking device remains closed.
When the circuit of the locking device is closed, the locking device opens. Possible causes:
- An authorised identification device is activated on the reader. The relay contact of the SmartRelay closes.
- The button is actuated. The relay contact of the SmartRelay closes.
- A remote opening of the SmartRelay is performed.
You can use the following cable types under the following conditions. (For detailed wiring information, see Information on cabling).
Number | Framework conditions | Cable type |
|---|---|---|
1 | Cable length power supply unit to controller ≤ 15 m (15 m outward and 15 m return) | F-YAY 2x2x0.6 |
2 | Cable length controller to reader (or controller to button) ≤ 15 m (15 m outward and 15 m return) | CAT5, shielded |

Locker system with direct cabling
The locker of the locker system opens when power is supplied to the locker locking device. Normally, the contacts of the SmartOutput module are open and the current does not flow through the contacts of the SmartOutput module to the locker locking devices. When the contact on the SmartOutput module is closed, the locker opens. Possible causes:
- An authorised identification device is activated on the reader. The relay contact of the SmartOutput module closes.
- The button is actuated. The relay contact of the SmartOutput module closes.
- A remote opening of the SmartRelay is performed.
You can use the following cable types under the following conditions. (For detailed wiring information, see Information on cabling).
Number | Framework conditions | Cable type |
|---|---|---|
1 | Cable length power supply unit to controller ≤ 15 m (15 m outward and 15 m return) | F-YAY 2x2x0.6 |
2 | Cable length controller to reader ≤ 15 m (15 m outward and 15 m return) | CAT5, shielded |
