Installation
Mount the metal housing onto the wall or secure the PCB module to an appropriate housing
Connect the Live, Earth and Neutral terminals to an un-switched fused spur.
Connect the 24v power output to the system.
Switch on the AC supply and confirm that the ‘AC Mains ON’ green LED is lit.
External Power Supply (AC Supply)
The power supply has a three-way terminal block for Live, Earth and Neutral connections. When supplied boxed,
earth is connected to the metal enclosure and the lid earthed with a flying push-fit lead.
24VDC Power Output
Terminal blocks are provided to connect to the system. The output is floating and can be referenced to earth if
required. The output is short circuit and overload electronically protected and is suitable for switching highly
inductive loads. The output is controlled by the ON/OFF input (see above).
AC Mains ON LED
The ‘AC Mains ON’LED will indicate if the Mains voltage is present.
Auxiliary Power Supply (Batteries)
The D2412 and D2413 units are compatible with 2.1Ah, 7 or 8AH and 17Ah Sealed 12VDC VRLA (Lead Acid or
Gel) batteries which should be connected to the “BATT” terminals. If two 12VDC batteries are used, they must
be connected in series using the link cable provided .
Battery Protection
The batteries and electronic circuitry are protected against reverse polarity connection by a self-resetting
electronic fuse.
Maintenance
There are no serviceable parts. No maintenance is required other than routine periodic testing.
Please note that high voltage is present under the cage –handle with care. Do NOT touch. Do NOT
remove the cage.
