Power Supply
The primary and standby supplies are calculated to suit the system alarm and
standby requirements. If the primary power supply fails, the secondary supply will
provide sufficient current to maintain the system fully operational for a period
determined by the added options to the zone circuit. Special considerations must be
taken when strobes and vibration pads are fitted. This is due to the higher alarm
current required for these devices.
4.2.3.1
Primary Supply
The primary power supply is a switch mode power supply fully regulated and
adjustable to the required voltage, it has the following features:
Universal AC input 85-264V AC, 47-63 Hertz
Output voltage 15V dc adjustable to +/- 10%
Output current 3.3A @ 12V, 5A power supply is optional
Built-in EMI filter, low ripple noise
Short circuit, overload and over voltage protection
Note
: Power supply voltage output can be adjusted (if required) to the nominal
voltage using potentiometer on the power supply PCB. The battery charging current
is shown in the following table:

4.2.3.2
Standby Supply
Battery capacity is calculated to suit the system requirement
1
. The standard RFS-1
is normally fitted with 7AH battery, if required, additional 7AH battery can be fitted
inside the enclosure and connected in parallel with the standard battery to increase
the capacity to 14AH.
