The Alpha Communications / TekTone CM800 Tek-Care series emergency-call system is designed for multifamily dwellings housing the elderly or handicapped or for other emergency-call/ panic type applications. Any tenant requiring emergency assistance can signal the building manager, security guard and/or neighbors by activating a conveniently located pullcord (or push-button) switch in each apartment or remote signaling location. Depending upon the system option(s) selected, the activation of the pullcord switch can activate the master (CM800) annunciator, apartment dome lights, floor bell(s) and individual apartment electric door opener(s). The CM800 master annunciator is modular and can be flush, surface or desk mounted and is available in any size, in multiples of four (4) lights. The CM800 features built-in tone signal and tone silence button and light. Model ST005D 'TEST' buttons are optional, but strongly recommended for lamp testing each module.
