The Ei129 Switched Input Module will trigger interconnected alarms if an external device is activated, such as a sprinkler system.

It is mains powered with rechargeable lithium back-up and is compatible with 3000, 2110e, 160e and 140RC Series alarms by mounting directly underneath. The fire/sprinkler system is then simply wired through the Ei129 to link to all connected alarms.

n.b. Only one Ei129 is required per alarm system, as long as all alarms are interconnected.
