In low airflow applications with smooth ceilings, space the sensors to
provide a maximum coverage of 81 square meters (900 square feet)
under ideal conditions.
•
Refer to NFPA 72 for specific information regarding sensor spacing,
placement, and special applications.
Follow these guidelines to install wiring:
•
Install all wiring in compliance with the National Electrical Code
(NEC), applicable local codes, and the special requirements of the
Authority Having Jurisdiction and the system control panel’s SLC
requirements.
