E2610-LEL

Rev 10.05.2021

For easier connection, terminal blocks of E2610 series devices are removable. To dismount
the terminal block, pull it off from the PCB. Connect the power terminals N and L to the 24
V power source if you are using detector version -24 or to 230 V AC mains if you are using
detector version -230 (see diagram below).

Terminals

RE1 NO

Relay 1, normally open terminal

RE1 COM

Relay 1, common terminal

RE1 NC

Relay 1, normally closed terminal

RE2 NO

Relay 2, normally open terminal

RE2 COM

Relay 2, common terminal

RE2 NC

Relay 2, normally closed terminal

L

90…265 VAC Phase (optional 24 VAC / VDC)

N

90…265 VAC Neutral (optional 24 VAC / VDC)

The terminals on the E2610 series devices are suitable for a wide range of wires with
cross-section 0,2...1,5 mm

. We recommend to strip the wire end by 5...6 mm and tin it, or

to use the wire end sleeves. To connect the wire, loosen the screw, insert the wire end into
the terminal hole and tighten the screw.

Connect external devices. Relay switch-over outputs may be used to control directly 24 V or
230 V (for versions -24 and -230 respectively) powered alarm sirens, ventilation fans,
shut-off valves, or other actuators. Attach terminal blocks to the board.

4. Push enclosure to the base.
