Featuring 64 first stage/channel alarm sounds which can be selected via an internal switch. The alarm tone frequencies for the first 2 stages are independently selectable. Each tone can be remotely triggered e.g. via an external relay, to change to a second, third or fourth stage/channel alarm sound. The enclosure features a threaded flame path, triple cable entries and a large termination area – all of which significantly reduce installation time.
