6.1.3 This Smoke Alarm can only interconnect with TRADEFORCE Model
TRFSD240I, TRFSD240PE, TRFSD240PERL Smoke Alarms; Heat Alarm
model HA240 and visual Signaling Device model SL240 and isolation relay
model RK10A/9. Interconnection with other brands may cause damage or
result in a shock or fire risk and void warranty.
6.1.4 Due to “noise” from electromagnetic interference, up to 24 units of smoke
alarms and compatible products may be interconnected.
6.1.5 There are five terminals in the supply terminal block, marked 9V, A, SW, N,
LOOP. It is important that the alarm be wired correctly to ensure correct
operation. Incorrect wiring to the Smoke Alarm will damage the unit and void
the warranty.
6.1.6 A total maximum of 250 meters (820 feet) of wire can be used in interconnect-
ing smoke alarms.
6.1.7 All final sub-circuit conductors including the signal conductor must be a mini-
mum size of 1mm² with 250V grade insulation.
6.1.8 Interconnected Smoke Alarms must be connected to the same final subcircuit.
6.1.9 Do not use any wire that could later be confused with the normal house wires
for the interconnect wire. For example, green/yellow earth wire.
6.1.10 Do not connect AC power wires to SW interconnect terminal. These will
damage smoke alarms.
6.1.11 Do not connect the SW interconnect wire to any device, except the SW
interconnect terminal of smoke alarm. Otherwise, smoke alarm will be dam-
age.
6.1.12 Switch wire (SW) only can drive the RK10A/9 and smoke alarms.
6.1.13 Do not connect 9V wire to AC power or SW interconnect terminal.These may
damage smoke alarms.
