Connect any ceiling-mounted detectors and/or
manual pushbuttons – see connection diagrams.
Terminal resistors must be properly installed!
Insert and connect smoke alarm module (option).
The alarm module cannot be used if relay contacts
7, 8 and 9 are already in use.
In order to comply with protection class II
insulation), the 230 V power lead should be installed
with double insulation up to the connection terminal.
Remove cable insulation at the end.
Connect 230 V power lead to terminals.
Close the shock hazard protection cover and screw
down.

Implementing the Reset mode:
Automatic reset – Jumper in position "A"
(as-delivered condition)
The EMR smoke detector automatically resets
following an alarm trip and as soon as there is no
smoke or test gas in the smoke chamber. Status
display returns to green.
Manual reset – Jumper in position "B"
A manual reset is mandatory in emergency exit
control systems (in accordance e.g. with IfBt Bulletin
5/983), item 3.1.4).
Status display flashes green as soon as there is no
longer any smoke or test gas in the smoke chamber.
Reset is performed by pressing the reset pushbutton.
If the manual reset mode has been implemented,
attach the enclosed RESET label.

Remove the red protective cap from the smoke
detector unit.
Switch on power supply – status display should show
green.

Setting the hold-open point:
Open door leaf and engage hold-open device .
Loosen screws .
Set door leaf to required angle and hold in this
position .
Note: When adjusting the hold-open device to the
maximum door angle, ensure that the cable is not
caught or jammed and that the anchor disc of the
magnetic unit can freely move.
Re-tighten screws .
The door cannot be opened beyond the hold-open
point; fix a door stop (accessory) at this position .
Setting the pull-off force:
10
Adjust the pull-off force to suit the door width and
size of door closer.
EN 1155 states that the release torque at 90° door
opening angle should be between 40 and 120 Nm.
If the pull-off force is set too high, damage might occur
at the hinges and the fixings of the door closer system.

Functional checks
Ensure compliance with instructions for use and also
the safety instructions provided on the test gas
container and safety datasheet.
Open active door and engage hold-open.
Spray test gas (Hekatron 918/5) from a distance of
approx. 10-15 cm towards the smoke chamber. After
approx. 4-6 short bursts, the status display should
switch to alarm (red). If the EMR is equipped with
the RS alarm module (option), an audible alarm is
also sounded.
The hold-open device is tripped and released, and the
door closes.
13 Fit dust protection cover supplied so that dust is
prevented from entering the smoke detector during
any subsequent building or finishing work.
Prior to final commissioning, remove the dust
protection cover and perform a further function
check procedure as described in item 12.

FINAL INSPECTION AND MAINTENANCE
☞
See instruction sheet relating to the use and
application of hold-open systems.
If the EMR lintel-mounted smoke detector is used in
rooms with a high dust content, ensure compliance
with the specified maintenance intervals. These may
even have to be reduced in order to ensure that dust
deposits in the detector do not give rise to nuisance
tripping.
