Abstract
An apparatus includes a wireless transceiver and a processor. The wireless transceiver may be configured to communicate wirelessly via a wireless network with an annunciator remotely located from the apparatus and a plurality of call light boxes remotely located from the apparatus. The processor may be configured to (i) control reception of an alarm message from one or more of the call light boxes in response to an event, (ii) illuminate a hall indicator in response to reception of the alarm message, (iii) receive a cancellation message from at least one of (a) one or more of the call light boxes and (b) the annunciator that cancels the event, and (iv) extinguish the hall indicator in response to cancellation of the event. The hall indicator may change color over time until the event is canceled.
