Parameter Options - MSB1001PT only
Programming is carried out using an infrared programming tool. Please note that the full range of parameters is
accesible via the QuickSet Pro; the HP18 offers different/limited programming options.
Off Delay
The Off Delay may be set between 1 minute and 96 hours using the QuickSet Pro, or at 5, 10 or 20 minutes with
the HP18. A 10-second Off Delay is available for walk-testing the product. In a typical office environment, the
default 20-minute Off Delay is usually satisfactory.
Response (Automatic/Semi-Automatic)
Where absence detection is required (i.e. the user manually turns lights ON if required but lights still turn off
automatically once an area is vacated), semi-automatic operation can be set via the programmer.
Power Up Setting (On/Off)
Set to ON the detector will automatically switch its outputs on when Mains is applied. If set to OFF, the detector
will power up without turning its outputs on, wait for 30 seconds and THEN look for movement. Only if the area is
occupied will the output switch on at this time. The detector must be set to Power Up ON when used in
conjunction with semi-automatic operation.
Photocell Mode (Passive/Active/Disabled)
The MSB1000PT has an in-built photocell. The photocell has three modes of operation - Passive, Active and
Disabled. Its operational behaviour is governed by the setting chosen and by the values stored in the Upper and
Lower thresholds (see Fig. 11).
Passive - The photocell will inhibit turn-on of the controlled load if sufficient natural light is available. It will not turn
the load off whilst an area is occupied
Active - The photocell will turn the controlled load on and off as required whilst natural light levels fluctuate during
a period of occupancy. This mode of operation operates in conjunction with a passing cloud timer (PCT). The
PCT is asymmetrical in operation - the load will be switched on immediately that the light level falls below the
lower set point, however, the load switches off only if the light level exceeds the upper threshold continuously for
a period equal to the Off Delay.
Disabled - The photocell has no effect.
24 Hour Cycle (Yes/No)
Not applicable.
Defaults (Fixed on MSB1001T)
The units are supplied with factory default settings (Power-Up On, fully Automatic operation, a 20-minute Off
Delay, no 24 Hour Cycle, Passive Photocell).
