washers and screws using a 3/16" hex key.
3.3.6 Orienting the flame detector
► Illustration on the fold-out page (Figure C)
1. Release the locking screws (C-4, C- 5) using a 3/16" hex key so
that the flame detector can be rotated.
2. Point the flame detector towards the protected area and make
certain that the view of the area is unobstructed.
3. Secure the flame detector in that position by tightening the locking
screws (C-4, C- 5) on the tilt mount using a 3/16" hex key.

To change the configuration parameters the following accessories are
required:
Mini Laptop Kit and corresponding manual:

The mini laptop, pre-loaded with the host software, enables you to
reconfigure settings or perform diagnostics on all Dräger
Flame 2xx0 detectors.
Dräger Flame USB RS-485 Kit and corresponding manual:

The harness kit with RS-485/USB converter, used with the host
software, enables you to connect to any available PC or laptop to
reconfigure settings or perform diagnostics on all Dräger
Flame 2xx0 detectors.
Possible alarm delay settings
The flame detector is equipped with an alarm delay option. It can be
set to one of the following options:
Antiflare (A)

The antiflare mode is selected to prevent false alarms in locations
where fast flares may be present. The time delay for fire alarms in
this mode is calculated by the detector software and ranges from
2.5 to 15 seconds (usually less than 10 seconds).
or
0, 3, 5, 10, 15, 20 or 30 seconds

When an alarm threshold condition occurs, the flame detector delays
the execution of the alarm outputs by the specified period of time. The
flame detector then evaluates the condition for 3 seconds. If the alarm
threshold condition is still present, the alarm outputs are activated. If
the alarm threshold condition no longer exists, the flame detector
returns to its standby state.
