Section 6 of 14
Relay and lock
Three working modes, pulse length and opening from the panel.
On a valid tap the device can release a lock. Pick the mode that matches what is fitted in the door.
- Off
- The output is unused. The device only records working time.
- Pulse
- The usual setting. The output is open at rest and closes for the length of the pulse after a tap. Suits an ordinary electric strike.
- Inverted
- The output is closed at rest and the pulse opens it. That is how fail-safe magnets work, holding the door with current.
Pulse length is adjustable from 0.1 to 10 seconds, 3 seconds out of the box. A second tap during a pulse extends the window rather than cutting it short, so two people walking in one after another do not shut the door on each other.
A separate setting releases the lock ON ENTRY ONLY. Exits are then merely recorded — useful when the door opens from the inside with a handle or a button.
The panel also has an open button on the administrator account. It behaves like a card tap but records nothing.
Opening from the other side of the door
From the other side of the door you open it with an exit button wired to the same cables as the device. It works independently of the reader and records nothing.
- Electric strike (pulse): a normally open (NO) button in parallel with the device, one wire to contact 3 (positive from the supply), the other to contact 2 (positive to the lock).
- Magnetic lock (inverted): a normally closed (NC) button in series in the positive wire, between contact 2 and the magnet.
- A second reader instead of a button: with a strike, wire the contacts of both devices in parallel (3 to 3, 2 to 2); with a magnet, in series (contact 2 of the first to contact 3 of the second, contact 2 of the second to the magnet). Each device keeps its own records.
