2. Installation

Follow these steps for installation:

Drill a 65mm hole in the ceiling.
Carefully prise off the cable clamps.
Make connections to the pluggable terminal blocks.
Insert plug connectors and secure using the provided cable clamps, then clip terminal covers to the base.
Fit detection blind (if required) and desired lens.
Clip fascia to body.
Bend back springs and insert into ceiling.

Diagram shows a sequence of steps for mounting the sensor in a ceiling, including drilling, wiring, and securing the unit. It shows drilling a hole, connecting wires, fitting the sensor body, and attaching the fascia and springs.

Wire Preparation

Use pluggable screw terminals. It is recommended to make connections to the terminal before fitting to the sensor.

Wire gauge: 0.75-2.5mm².

Strip length: 8mm (min 6mm, max 11mm).

Maximum cable lengths:

200 meters (total) max. for 1mm² CSA (Ta = 50°C)
300 meters (total) max. for 1.5mm² CSA (Ta = 50°C)

3. Functions

3.1 Daylight Harvest (Daylight Regulating)

The daylight sensor measures ambient natural light and calculates the required electrical light to reach a target lux level. This demand is communicated to the LED driver via DALI signal to adjust light output accordingly.

Graph illustrating daylight harvesting: shows Light level on the Y-axis and Time on the X-axis. It depicts three lines: "Natural light", "Daylight controlled light", and "Normal Electric Light". The "Daylight controlled light" line follows the "Natural light" line up to a certain point, then maintains a constant level (the target lux) by adding "Normal Electric Light" when natural light is insufficient.

3.2 Lux Off Function

The built-in daylight sensor can automatically switch off the fixture when the ambient natural light level exceeds the set daylight threshold, indicating that artificial light is not required.

3.3 Dual DALI Output Control

The HIR32 features two self-powered DALI output channels for connecting two groups of LED drivers. Both channels share the same control settings from the occupancy sensor and photocell.

System Capacity	DALI channel	DALI Driver < 2mA
HIR32 includes 2 channels total 80mA max. DALI PSU	DALI PSU Channel 1 (max 50mA)	25 pieces
	DALI PSU Channel 2 (max 30mA)	15 pieces

3.4 Manual Override (Push Function)

Three push terminals (P1, P2, P3) allow temporary control of light brightness, on/off status, and color temperature for the two DALI channels. Settings revert to daylight harvest mode after the sensor's time-out period.

P1: Long push adjusts hold-time brightness for DALI channel 1; Short push ([less than] 1s) toggles on/off for channel 1.
P2: Long push adjusts hold-time brightness for DALI channel 2; Short push ([less than] 1s) toggles on/off for channel 2.
P3: Long push cycles through color tuning (requires DT8 LED driver); Short push ([less than] 1s) resumes automatic daylight harvest mode.

4. Wiring Diagram

Diagram shows the wiring connections. The HIR32 sensor is connected to mains power (L, N). Its DALI outputs (DA1, DA2) are connected to two separate LED drivers. Each DALI channel has a maximum device capacity indicated (e.g., Max. 15pcs for DA1, Max. 25pcs for DA2). The manual override push terminals (P1, P2, P3) are also shown connected to the sensor.

5. Description of the Button Functions (Remote Control HRC-11)
