EBMHS
Miniature HS PIR Presence Detector (standalone)
Overview
The EBMHS series of miniature PIR (passive infrared)
presence detectors provide automatic control of lighting
loads with optional manual control.
Three models are available: premium, direct dim, and
analogue dim all of which will switch incandescent,
fluorescent and compact fluorescent lighting. The direct
dim variant controls DALI or DSI digital dimming ballasts
whilst the analogue dim variant controls 1-10V dimming
ballasts.
The unit detects movement using a PIR sensor and turns
the load on. When an area is no longer occupied the load
will switch off after an adjustable time out period.
These units come complete with clips allowing unobtrusive
flush mounting into ceiling tiles or solid ceilings.
All functionality is fully programmable using an IR handset.

Features
PIR Sensor
Detects movement within the unit’s detection range,
allowing load control in response to changes in occupancy.
IR Receiver
Receives control and programming commands from an
IR (infrared) handset.
Light Level Sensor
Measures the overall light level in the detection area
Status LEDs
The LED flashes Red to indicate the following:
Walk Test LED active
Valid setting received
RJ11 connector
The sensor head has a flying lead with a RJ11 plug at the
end plugs into the RJ11 socket on the power supply.
Power supply
This power supply has a 6A relay. It also has connections
for an external switch that can be used to turn on the load
when absence detection mode has been set or raised /
lowered with dimming variants.

Installation
The product is designed to be mounted directly to a luminaire, either on the inside or outside. The detector should be
sited so that the occupants of the room fall inside the detection pattern (shown opposite), at a recommended ceiling
height of 2.8m. Note that the lower the sensor is installed the smaller the detection range will be, subject to the
parameters shown on the detection diagram.
For optimum operation of the lux sensor, the lens must shielded as much as possible from the light source.
If flush mounting in a panel >6mm thick, remove bottom of retention arms with side cutters.
Avoid direct sunlight entering the sensor.
Do not site within 1m of forced air heating or ventilation.
Do not fix to a vibrating surface.
Sensor functionality
Detection mode
Presence When movement is detected the load will automatically turn on. When the area is no longer occupied the
load will automatically switch off after an adjustable time period.
Absence The load is manually switched on. When the area is no longer occupied the load will automatically switch
off after the adjustable time period has elapsed.
Switch operation:
PRM single switch: short press turn on, long press turn off.
EBMHS-DD & EBMHS-AD single switch: short press turn on, short press turn off, press and hold cycles dimming.
EBMHS-DD & EBMHS-AD two way switch: up button short press turns on, press and hold to dims up. Down
button short press turns off, press and hold dims down.
In either case, sensitivity to movement of the PIR sensor can be adjusted using the Sensitivity parameter.
HINT: To assist in setting the Sensitivity, turn on the Walk Test LED which will flash red when movement is detected.
Switch Level On/Off
Occupancy detection can be made dependant on the ambient light level using the Lux On Level and Lux Off Level
parameters.
Maintained Illuminance (daylight harvesting) - DD and AD variants only
The detector measures the overall light level in the detection area and calculates the correct output for the luminaires, to
achieve a preset lux level (maintained illuminance or daylight harvesting).

Overview
It is a requirement of many fluorescent lamp manufacturers to have the lamps on at maximum output for a period of
time to guarantee lamp life (refer to the manufacturer’s datasheet for details). As the EBMHS-DD & AD are able to
dim the lamps using DALI/DSI or 1-10V, the products provide a facility to disable this for a given period of time.
Operation
By setting the “Burn in” parameter, you can select a time during which the lamps are not allowed to deviate from
maximum output. The unit counts the time, and even remembers how long has elapsed in the event of a power
failure. To cancel the burn in function, simply select a time of 0. Note that when the lamps are changed, the burn in
time should be set again.

Installation
Surface mounting
Use the lugs on rear of detector to
secure into thin sheet metal (1mm
max.).
Side mounting
Flush mounting
The product can be mounted
using the flush mount ring as
shown. If flush mounting in a
material that is greater than 6mm
thick, remove bottom of retention
arms with side cutters. A 32mm
diameter hole will be required to
mount the flush mount ring.
