ESL 700 Series Installation Sheet

ESL 700 Series Conventional Smoke and Heat
Detector Installation Sheet
Description
The ESL 700 Series 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. For a
list of model numbers, see Table 1. For a list of accessories,
see Table 2.

[1] UL Listed for releasing devices such as electromagnetic door
holders, fire dampers, or smoke dampers.
High voltage (120 V) base and head
The 702RE and 702RU bases have a special plastic protrusion
built in to prevent insertion of a low-voltage detector head into
a base containing damaging high voltages (120 V). These
bases can only be used with 731U heads. The 731U includes
auxiliary relay contacts and is only required when connecting
high voltage to the auxiliary relay.
Note: The 731U heads can also be used with 702E and 702U
bases for low voltage applications.
