Remote Pc Connection; Aux. 24V Output; Installing The Standby Battery Supply - C-TEC CAST XFP Engineering Manual

CAST XFP 32 ZONE ANALOGUE ADDRESSABLE FIRE ALARM PANEL

Remote PC connection

A four-way RS232 molex connector
(PL1) is provided on the Main
Control PCB for the connection of a
Windows based PC/laptop.
The ONLY way to program this panel
is to use the panel's PC programming
tools (Part No. XFP507).
The SAF7070000 lead supplied with
the tools should be used to connect
the panel and PC as shown in Fig.9
right.
Note: A USB to RS232 connector is
also available (Pt. No. SAF8080000).

Aux. 24V output

One fused 24Vd.c. output, rated at 100mA, is provided and can be used for supplying power to ancillary
fire alarm equipment.

Installing the standby battery supply

There is a risk of explosion if incorrect battery types or sizes are used. Always replace both
batteries and always dispose of used batteries in accordance with the battery manufacturers
instructions and local regulations. Batteries are heavy and can produce dangerously high
currents if shorted. Take care when handling and routing battery leads to avoid damage.
Two new, good quality and fully charged 12V valve regulated lead acid (VRLA) batteries are required
as the emergency stand-by power supply for the panel. The batteries should be connected in series
and located in the panel's enclosure, as shown in Fig.10 below. Battery leads, link wire and cable
ties are provided in the panel's accessory pack. Run the battery leads through the slits in the panel's
lower plastic ribs and secure the batteries into position using the cable ties.
The panel's sophisticated battery monitoring unit protects the batteries against deep discharge by
activating a cut off circuit when the stand-by supply voltage reaches 21V approx. If batteries are not
fitted, are discharged or in poor condition, a PSU fault will show at the panel.
The capacity of the batteries used will depend upon the required stand-by time. To calculate the
batteries required for any given stand-by period, refer to the battery calculation guide on page 47.
