H The detector reacts most sensitively to movement which proceed at right
angles to the coverage zones (the direction of the arrow in figures 1 and 2).
H The detector's coverage area is limited by any solid objects.
H The detector is designed to achieve optimal response sensitivity and a high
level of false alarm suppression. Nevertheless, you are recommended to
take note of the following points (see also figure 10):
- Do not direct the zones at sources of heat or cold, nor at points subject to
strong sunlight.
- Direct the zones towards uniform references. Zones which are directed
towards heaters (including floor heating equipment) can reduce the prob-
ability of detection of movement.
- If it is impossible to avoid positioning the detector above heaters, you
must keep them at a minimum distance of 1.50m / 5ft away!
H The integrated breakage/removal contact and the «real time» antimask sur-
veillance system mean that security against tampering satisfies the highest
requirements. What is more, all the functions of the entire detector (includ-
ing the detection sensors) are constantly monitored.
Anti-masking and alarm memory features are not verified by UL.

Installation

The detector is intended for use in inside rooms.
Do not remove the printed circuit board from the detector. There is a dan-
ger that it may be damaged!
1. Open the detector (figure 3).
2. Mount the detector on a stable vertical surface.
- Select the height (h) above the floor according to figure 1 or 2.
- Corner mounting and 45° installation (right / left) are possible without any
accessories (see figure 4A).
- Detector must be inclined at an angle of 2° when mounting above 3m / 10ft
in order to detect crawling intruders and to ensure the detection range (see
figure 4B).
- The cable is introduced through one of the knock-out points A (see figure 5).
3. Wire the connections as shown in figure 7.
4. For strain relief on the connection cable, pierce the lug B (figure 5) and fix
the cable with a cable cleat.
5. Select the desired settings as shown in the section on "Programming".
6. Replace the cover, screw it down with the screw provided, and close the
screw cover (figure 3).
Detector breakage/removal monitoring Figure 6
If the detector is forcibly removed from the mounting surface, a sabotage
alarm is triggered.
For this, the detector base must be secured with an additional screw.
This feature is not verified by UL.
Control inputs

Remote control of the walktest indicator. Use switch DIP1 to select the polarity
of the control signal.
Walk test remote control is not verified by UL.
Set/unset remote control Terminal 5
Remote control of the set/unset state. Use switch DIP4 to select the polarity of
the control signal.
An open control input is HIGH (internal pull-up); for control with active
HIGH, a resistor (typ. 2kΩ, max. 47kΩ/detector) must be switched to 0V.
Programming
You can use switches DIP1 to DIP8 to select the following functions:
DIP ON OFF (default)

Functions
Detector function monitoring (self-test) DIP5
A self-test is always carried out when the supply voltage is applied. The detec-
tor is also equipped with a periodic self-test.
A malfunction (such as a sensor failure) is indicated as a disturbance by the
continuously red LED, and also at the disturbance output (terminals 7+8); and
if DIP5 = ON, it is also outputted to the alarm relay in the unset mode.
Antimask surveillance
When masking is performed which restrict the motion detection, an antimask
signal is outputted via output DIST. & AM (terminals 7+8), and during walktest,
the masking indicator (LED lights green) is activated.
To ensure reliability of operation, detector covers must be replaced if they
have been sprayed. Cleaning them is not enough.
Sensitivity of antimasking surveillance DIP6
- Standard
Recommended setting to detect masking.
- High
This setting enables faster and more sensitive masking detection for very
high risks.
Depending on the masking material, the range of the antimask surveil-
lance is approximately 0.20m / 0.7ft.
Antimask surveillance function DIP7
- Real time
The antimask signal follows the state of the detector. Masking will only be
indicated as long as the detector is masked. This is the setting recom-
mended by the manufacturer.
- Latch
Once the antimask signal is activated, it is retained (stored) on self-hold until
it is reset by carrying out an antimask surveillance reset.

IR270CT Instruction for use
Antimask surveillance reset
- Variant1
With masking present, switch over to walktest ON:
- Remove the masking and trigger the motion alarm;
- Switch back to unset, and the antimask surveillance will then be re-initial-
ised.
- Variant 2
Restart due to voltage cut.
The detection area must be checked after every reset or restart.

Memory displays
Set memories are shown in the unset with walktest OFF state.
The alarm memory (LED flashes red) shows the result of the last set period.
This memory is always reset when the system is next in the set state.
The masking memory (LED flashes green) is set when an event of the rele-
vant type has been continuously or temporarily present during the previous
set period. This memory is reset when the system is next in the set state, pro-
vided that the masking is no longer present.
Commissioning
1. Switch on the supply voltage.
During the self-test and the start-up phase with walktest ON, the LED flashes
red slowly for about 1 minute.
- When the LED goes out, the detector is ready.
- If the LED lights red continuously, there is a fault in the detector.
2. Carry out the walk test, i.e. check the complete monitoring area to make
sure the alarm triggers:
Walk upright across the active area at a rate of about 1 step per second in the
direction shown by the arrows (fig. 1 or 2) and pause. An alarm should be trig-
gered in approx. 2 to 3 seconds!
The detector must also trigger an alarm if the active area is crossed near to its
edges.
Sealing the detector
Function
If sealing of the detector is prescribed, apply an adhesive seal over the gap
between the base of the detector and the cover.

Maintenance

Check the function of the detector regularly (at least once per year) - carry out
a walktest, check for dirt and inspect the fixture.

Options
Curtain mirror IRS272 Figure 2
The IRS272 curtain mirror has overlapping active zones forming a monitored
area to provide secure monitoring against intrusion. At installation heights
above 3m / 10ft, mount the detector with a downward inclination of 2°.
Changing the mirror:
Remove the wide-angle mirror from the cover using a No. 1 screwdriver (Fig.
8) and replace it with an IRS272 curtain mirror.
Use the sensitivity settings «High values», «Standard» or «Increased
stability».
Check the mirror for soiling and damage. Do not touch the pyrosensor!
Mounting bracket IRUM20, IRUM30 Figure 9
The mounting brackets IRUM20 (wall-mounting) and IRUM30 (ceiling mount-
ing) enable the detector to be rotated through ±45° and tilted through
+10°/–15°.
The monitored zone can differ from that shown in Fig. 1 or 2, depending
on local conditions and the setting of the mounting bracket.
