Alarm Annunciator Panel AAP-10

The AAP-10 Alarm Annunciator Panel product line has been discontinued.

The AAP-10 Alarm Annunciator Panel provides visual and audible alarm indications for single or grouped digital inputs.

It is manufactured from universal cells, which can be assembled in an array to provide the number of alarm channels required to a suit individual system configuration.

Each cell of the AAP-10 contains 4 digital inputs, 2 alarm extension relays outputs and up to 4 independently LED illuminated windows of customised colours. Each replaceable alarm lamp assembly has inherent LED redundancy. A maximum of 63 cells plus operator keypad can be set into an array to suit any application.

Additional or standard system functions are configurable using up to 6 external key inputs.

A clear plastic cover with a diffuser sheet protects the alarm transparency within a plastic bezel.
