Connection to RFP V2
Field wiring as shown in Figure 2 below is same as the standard RFP zone wiring.
The bi-metallic switch contact is connected between Interconnect and positive
terminals (with protection diode and series resistor) on SUB1034 (60
⁰
) / 1035 (80
⁰
)
board. When the temperature in the roof space reaches the fixed temperature value,
the bi-metallic N/O contact closes, Interconnect voltage goes high and activates all
the Smoke or Heat Alarms interconnected to HS60V2 or HS80V2. The red LED will
turn on only when the heat switch closes. The roof space heat detector provides 12V
output for Remote Indicator Light (RIL), with selectable “Latching” and “Non-
Latching” mode. The RIL will be reset when key-switch on the panel is switched to
“OFF” or “FIRE” position.

Limitations of Smoke / Heat Alarms
Smoke / Heat Alarms have significantly helped to reduce the number of fire fatalities
in Australia where they are widely installed.
However, independent authorities have stated that they may be ineffective in some
circumstances. There are a number of reasons for this:
•
Smoke / Heat Alarms will not work if they are not connected to the RFP6 V2
series or if the power supply of the panel has failed.
•
Smoke / Heat Alarms will not detect fire if sufficient smoke / heat does not
reach or prevented to reach the Alarm. Smoke/Heat may be prevented from
reaching the Alarm if the fire is too far away, for example, if the fire is on
another floor, behind a closed door, in a chimney, in a wall cavity, or if the
prevailing air draughts carry the smoke/heat away. Installing Smoke/Heat
Alarms on both sides of closed doors and installing more than one
Smoke/Heat Alarm as recommended in this manual very significantly
improves the probability of early detection.
•
Smoke / Heat Alarms which are not maintained or are tampered may not
function reliably.
•
Smoke / Heat Alarms may not be heard
due to background noise, distance
from the bedroom or closed doors.
•
A Smoke / Heat Alarms may not wake a person who has taken drugs or
alcohol.
•
Smoke / Heat Alarms may not detect every type of fire to give sufficient early
warning. They are particularly ineffective with fires caused by escaping gas,
violent explosions, poor storage of flammable rags and/or liquids, (for
example petrol, paint, spirits etc). Overloaded electrical circuits, arson and
children playing with matches.
•
Smoke / Heat Alarms do not last indefinitely. The manufacturer recommends
replacement after 10 years as a precaution.
