Honeywell UC1221PF

What is the Honeywell UC1221PF?

LightSpot PIR uses passive infrared (PIR) technology for advanced presence detection. Infrared programming for easy commissioning and re-commissioning using the QuickSet Pro hand held commissioning tool.

HC5AIt provides remote control for temporary user-override on/off and light level adjustment

It consist of Passive photocell, Active photocell and Regulating photocells where, Passive photocell holds lights off when area becomes occupied in bright ambient conditions. Active photocell switches lights on and off according to ambient conditions. Regulating photocell adjusts luminaire output to maintain constant light levels

Automatically flushing cisterns can waste a great deal of water.

In a typical installation, every cistern flushes automatically all day and all night, during weekends and holidays, whether the facility is being used or not. A 10 litre cistern can use 20,000 litres of water a month and most of it is wasted.

Presence-detecting LightSpot washroom controls provide a simple and effective way to cut the waste and save money by regulating the flow of water to automatic flushing cisterns.

Further savings can be made by switching off lights and fans in unoccupied toilet areas. With the dual-circuit version, the

flush control can be programmed independently from the lighting control.

To ensure that fresh, hygienic conditions are maintained during holiday shutdowns, an automatic daily flush takes place.

Features & Benefits::

Presence detection is by passive infrared, effectively enhanced to improve sensitivity to small movements.

Passive photocell holds lights off in bright ambient conditions. Active photocell has the capability to switch lights off in occupied areas.

Off delay: Period following the last observed movement after which lights switch off. Adjustable via QuickSet Pro.

Detection pattern and approx. range in metres at floor level for 2.5m mounting height (detection pattern is cone shaped).

Dual-circuit (1 x volt-free, 1 x switched-live output).

Switched-live influenced by photocell, volt-free output by presence detection only. Independent time delays can be programmed via QuickSet Pro.

Hand-held Controller provides local user override.

Remote programming ensures changes can be easily accommodated. Please see individual detector instructions for programmer compatibility.

Washroom mode. If no movement is detected in a 24-hour period, detector can be programmed to switch the load on for the duration of the off delay.

Solenoid valve included (UC1221P models only)
