Brook Self Test Unit LED Indicators
Normal Operation – Green LED on
Auto test/Dishcharge – Green LED off – Main LEDs on.
Fault indicators
Red flashing LED
Twice every 3 seconds –LED/Changeover fault
Three times every three seconds – Duration test fail
PCB SWITCH
The PCB mounted switch has two functions.
1. Press the switch for 1 second sets the time the unit
will carry out the self test function (This allows the user
to choose a convenient time for the unit to carry out the
test.)
2.Press the switch for 3 seconds starts a 5 minute test.

EMERGENCY LIGHTING LUMINAIRE INSTRUCTIONS
1. Remove the screws which hold the diffuser to the body.
2. Release gear tray by moving the two retaining hooks.
3. Fix base to wall or ceiling either direct or via conduit box, having
cleared an access hole in the body for the cable. If IP65 protection is
required use a weatherproof gland to seal the cable.
4. ISOLATE THE A.C. SUPPLY and connect unit. An unswitched 240V
A.C. supply must be connected to the Live (L), Earth and Neutral (N)
terminals on the PCB block. On Maintained circuits illumination can be
achieved by connecting a live (switched) input, or a link between L
and L1 either locally or through a remote switch. L1 is the switched
live input terminal
5. Plug battery lead into connector on the PCB.
6. Re-secure the gear tray into the base of the unit making sure that the
mains cable is not trapped by the PCB etc.
7. Refit the diffuser using the two screws.
8. Operational Check – Restore the A.C. Supply for 30 minutes and then
remove. The LEDs should illuminate for at least 10 seconds.
9. Restore the A.C. supply and check that the indicator LED is ‘on’.
ENSURE FITTING IS CHARGED FOR A MINIMUM OF 24 HOURS
PRIOR TO TESTING
OPERATION
NON-MAINTAINED
LEDs normally off and battery on automatic charge (Green LED ‘on’) when
A.C. Supply is healthy. Solid state circuitry automatically switches lamp on
when A.C. supply is interrupted.
MAINTAINED
LEDs normally on, when the supply to L1 is switched on. The battery is
on automatic charge (Green LED ‘on’). Lamp will switch on or remain on
if A.C. Supply is interrupted.
IM4 Instructions Issue 4 2016 IM4 Instructions Issue 4 2016
MONITORING
Green indicator lamp (LED) normally continuously ‘on’.
BATTERY
Sealed Nickel-Cadmium rechargeable battery pack.
TEMPERATURE
Performance figures measured at 25 degrees C.
FAULT FINDING AND CORRECTIVE ACTION
MONITORING LED NOT ILLUMINATED
A.C. Supply not healthy. Battery not connected. Charger failed.
UNIT NOT MEETING REQUIRED EMERGENCY PERIOD
May need cycling: Discharge then recharge for 24 hours. Re-test, Battery
pack may need replacing if emergency duration still not met.
LEDs NOT FULLY ILLUMINATED
If the LEDs are not illuminated check connections & if correct either the
battery pack or (less likely) the printed circuit board needs replacing.
‘Self-Test’ fitting – Function (option).
When the self test fitting is installed the light will:
• Carry out a monthly 10 minute function test.
• Carry out a 3 hour yearly duration test
The light will monitor for the following faults:
• Battery disconnection
• Charger fault
• Main LED array failure
Battery/Charger fault - 1 Red LED flash every 2 seconds
LED Array fault - 2 Red LED flashes every 2 seconds
In the event of a fault, the Green LED indicator will change to a
red flashing LED
