ABSTRACT:
Sequentially generated pulses are applied to respective groups of alarm and status condition responsive contacts. A memory is indexed in accordance with the pulses to store individual condition signals received from respective contacts in each group and activate alarm or status indicators. A lock switch operates facilites for partially disabling a manual acknowledge switch which turns off audible and blinking alarm indicators. A printer records the time and a character indicating the specific alarm contact which was activated. Alarm summary command or alarm status summary command switches may be selectively operated to produce a print out of all alarm conditions or a print out of all alarm conditions and the status of all status contacts. The system employs modular units which may be selectively connected in the system to provide lamp annunciator functions and/or printing functions for selective sized groups of contacts.
