Power requirements
MAIN POWER SOURCE REQUIREMENT
The FireCatcher Camera has a maximum power consumption P
max
= 10,7 W, corresponding with a current I
max
= 0,45
A at 24V.
Notice: Do not use Power over Ethernet to feed the FireCatcher Camera.
STANDBY POWER BATTERY CALCULATION
Calculation method: EN54-4:1998 (
Fire detection and fire alarm systems
—
Part 4: Power supply equipment
) defines
the need for standby power supply with rechargeable battery of a fire detection system. EN54-14 (
Fire detection and
fire alarm systems
—
Part 14: Guidelines for planning, design, installation, commissioning, use and maintenance
)
recommends a battery standby capacity of 24 hours for continuously monitored systems and 72 hours for non-
continuously monitored systems. BS 5839-1:2017(
Fire detection and fire alarm systems for buildings
—
Part 1: Code
of practice for system design, installation, commissioning and maintenance
) further introduces an ageing factor of
1,25 that allows for a battery degradation of 5% over 4 years. The standby time can be reduced to 6 hours for certain
categories if an emergency generator is present.
The FireCatcher Camera has a maximum power consumption P
max
= 10,7 W, corresponding with a current I
max
= 0,45
A at 24V. This results in a required battery capacity per camera as follows.

Cabling
The FireCatcher Camera supports 2 entry cables:
•
Combined power + alarm cable: FireCatcher Camera supports the use of conventional multi-core fire
alarm cable e.g. DIN VDE 0815 telecommunications cable.
•
Ethernet cable: standard 8-wire Ethernet cable. Araani recommends using a shielded network cable
(STP) of category CAT5e or higher.
The camera cable gaskets support cables with outer diameter between 4 and 9 mm (0,19 - 0,35 inch).
