Dear Mike,
This letter outlines Phase 2 of the Enzian Condominiums fire alarm project. Last summer,the
fire alarm panel malfunctioned and was replaced. Phase 2 was to be completed this spring.
This phase will include the installation of smoke/carbon monoxide and smoke/heat detectors
with integral sounders into each unit. Carbon monoxide detection will sound a local alarm and
call the fire department. Smoke detection will be a local, supervisory condition only. Heat
detection will activate a general alarm condition. Devices have an integral sounder base for
occupant notification, temporal 3 pattern for smoke or heat detection, and temporal 4 pattern for
carbon monoxide.
Drawings outlining device locations are attached. A battery calculation and equipment data
sheets are also included. Please let me know if you have any questions.
Sincerely,
Deborah L. Shaner, PE
Fire Protection Engineer
