The Problem
Audibility throughout the home is a priority,as a situation could
arise where a CO alarm is installed in a downstairs kitchen,which
has a fossil fuel burning appliance within it,and the alarm signal
may not be heard in the upstairs bedrooms or indeed other rooms.
The Solution!
Use the interconnect feature on the Ei261ENRC/Ei261DENRC to
connect to your existing Ei160RC smoke/heat alarm installation.
Then, you must introduce an Ei1529RC Alarm Control Switch
to provide control over the
whole system.
The interconnect feature allows the CO alarm to trigger all
Ei160RC mains smoke/heat alarms installed and vice-versa - giving
increased audibility in either a CO or fire situation. If all alarms are
sounding, pressing ‘Locate’ on the Ei1529RC Alarm Control Switch
will silence all the alarms except the alarm sensing a CO or fire
situation.This gives control over the system and allows occupants
to select the safest action and/or escape route.
Additionally, if found to be a false alarm,simply press ‘Hush’on the
Control Switch to silence the alarm.The entire alarm system can
also be tested regularly by pressing the ‘Test’switch.
