OPERATION.
The RK10A/9 Smoke Alarm Isolation Relay is a device
designed to provide compatible 240VAC Smoke Alarms with
a set of Normally Closed (NC) and Normally Open (NO)
change over contacts. This permits the Smoke Alarm to
trigger auxiliary devices such as strobe lights, sirens, bells,
burglar and fire alarm panels, activate emergency lights,
shutting down air conditioners or releasing magnetic door
holders. (See Figure 1)
The RK10A/9 will in the absence of mains power and only
operates when the smoke alarm is in alarm state.
The RK10A/9 Isolation Relay has an additional feature
capable of receiving a 24Vdc power signal from a fire panel or
external device which will activate a separate NO contact to
trigger another smoke alarm with a fourth terminal. This
feature allows the smoke alarm to be triggered by the fire
panel to initiate an early warning alarm. (See Figure 2)
COMPATIBLE SMOKE ALARMS
Note that when used with an output from the smoke alarm this
device is intended and designed only for use with the
following smoke alarms and devices;
LIFESAVER LIF3000, LIF4800RL, LIF5800R,
LIF5800RL, LIFHA240, LIFSL240
LANSON Lansd240P
WARNING: Use with other smoke alarms may damage this
device and the smoke alarm(s) and could create a definite
shock risk and would not be covered by any warranty.
The Isolation Relay RK10A/9 must be installed by a
Licensed Electrician.
Wiring from the Smoke Alarm N and S terminals must be
correctly connected to the RK10A/9 N and S terminals.
Incorrect wiring will short and damage the isolation relay
and the Smoke Alarm and will void warranty.
The Isolation Relay RK10A/9 is triggered once the Smoke
Alarm activates and sends a signal down the switch line.
Note there will be a 8 second delay before the relay operates
the RK10A/9’s Normally Open and Normally Closed contacts.
This is to help prevent any unnecessary false alarms from the
smoke alarm.
In the above case the changeover contacts of the relay,
connected to the output terminals may be used to make or
break an external E.L.V. or L.V. circuit operating at up to
240Vac 10A or 30Vdc 10A.
WARNING: UNDER NO CIRCUMSTANCES MUST AN
INSULATION RESISTANCE TEST BE CARRIED OUT
BETWEEN THE INPUT CONDUCTORS OF THIS
RK10A/9. SUCH A TEST COULD CAUSE
IRREPARABLE DAMAGE TO THE INTERNAL
CIRCUITRY OF THE DEVICE AND MAKE IT
INOPERATIVE AND FURTHER, THE WARRANTY
WOULD BE VOID UNDER THIS CONDITION.
INSTALLATION.
General:
The RK10A/9 requires no earthing conductor as it is double
insulated. It must be suitably fixed in position and protected
from mechanical damage. If the output terminals are
connected to low voltage (240V) circuits, the associated
wiring must be installed in accordance with the relevant
requirements of the SAA Wiring Rules, AS3000.
Warning: A combination of the N.O. and N.C. contacts is
not permissible and will not operate.
WIRING DIAGRAM
Figure 1: Connecting to Auxiliary Devices
By installing the RK10A/9 in this manner it will allow you
to operate such devices such as sirens, strobes, bells, lights,
air conditioners or any devices which do not exceed 240V
AC @ 10 Amps.
