4.1 INTERCONNECTING
With interconnected alarms, when one unit detects CO all units alarm. All horns will sound but only units detecting CO will flash their red lights.
A maximum of twelve Ei261ENRC/261DENRC CO Alarms may be interconnected along with an Ei128RBU & Ei128COV relay module (see “ACCESSORIES” on page 32).
Alternatively, up to twelve Ei261ENRC /Ei261DENRC CO Alarms and Ei161RC/Ei164RC/Ei166RC Smoke/Heat Alarms may be interconnected provided an Ei1529RC Remote Control is used in the system (see “ACCESSORIES” on page 32).
Do not connect these Alarms to any other model produced by another manufacturer, or to any other model of Ei Alarm, apart from those listed above. Doing this may damage the Alarms and could result in a shock or fire hazard.
The interconnect wire (minimum 0.75mm2 cable) must be treated as if it was Live. It should be insulated and sheathed.
