* If the ambient light has exceeded the set threshold, Relay 1 will not switch on. Relay 2 will not be affected by the threshold
setting and will operate as per normal (DGEMSR360P2 only).
Note:
The lux level threshold values shown in Table 4 refer to the minimum light level incident on the
sensor. Typical room light levels are considerably larger. Surfaces and materials in the space being
controlled will determine the amount of reflected light onto the sensor head.

Presence/Occupancy Detection
The Passive Infra-red (PIR) sensor uses an advanced detector and lens array to provide the ultimate coverage in its
class. The sensor head has two distinct detection sensitivity zone categories, major movement and minor
movement.
Major Movement
1
(Occupancy) is defined as a 60kg person, walking at >1m/s, across the field of view, with a
background ambient temperature of 20°C.
The PIR sensor will detect
Major Movement
within a 7m diameter circular area of its position when mounted at
2.7m from the floor as shown in Figure 9.
Minor Movement
1
(Presence) is defined as a hand and forearm at 0.9m from the floor moving through a 90° arc
in <1.5 sec with a background ambient temperature of 20°C.
The PIR sensor will detect
Minor Movement
within a 3.5m diameter circular area of its position when mounted at
2.7m from the floor as shown in Figure 9.
