4. Flush mounting relay (10-837)
4.1. DESCRIPTION
The flush mounting relay has an extensive number of functions that can be programmed
manually.
4.2. INSTALLATION
This relay is designed for flush mounting and has 5 pairs of plug-in terminals that simplify
wiring. To each terminal, 2 wires can be connected. The wire can have a diameter of max.
0,8mm. In order to insert the wire into the terminals, it must be stripped over a length of 5 to
6mm. The relay is directly connected to the bus. In case of a 2-wire connection, only a and b
are connected. If over 3 relays type 10-837 are connected, a 3-wire connection is required.
In this case, a, b and P must be connected and the relay jumper must be removed (fig.6). The
relay 10-837 is provided with a potentialfree relay output with a 230V/3A changeover contact
at the bottom. This relay output can be used as normally open (NO) or as normally closed (NC)
contact. Depending on the desired operation, screw terminal COM must be combined with NC
or NO. The relay is provided with an additional input (terminals M+ and M-) for connecting
a push button/switch. The relay can be connected to the Nikobus home automation system
via the in- and outputs (see technical catalogue Niko Access Control).
