Description

Model ESL 713-5U is a two-wire rate-of-rise and 57°C (135°F) fixed temperature heat detector. The Edwards 713-5U smoke or smoke with rate-of-rise heat detectors have field-replaceable optical chambers. The detector uses an optical sensing chamber to detect smoke and a fixed-temperature heat sensor to detect heat from fire. Locate the smoke detectors in an operating environment as defined. Mount the smoke detectors on a firm, permanent surface. Do not install heat detectors in areas with an ambient
temperature above 100°F (38°C).  Mount heat detectors on the ceiling no closer than 4 in. from the sidewall. On the wall, mount them between 4 and 12 in. from the ceiling. When determining detector placement, consider ceiling height, construction, and ventilation as these affect a detector’s performance. Each detector head is equipped with a breakaway locking tab
to prevent unauthorized removal of the detector head. For installations where unauthorized removal of the
detector head is not a concern, the head removes by simply turning counterclockwise.
However, when the head must lock to the base, break away the locking tab with a pair of pliers. Then, to remove the detector head, insert a small screwdriver into the slot on the side of the base, pressing in while simultaneously turning the detector head counterclockwise (
