Installation Instructions (PRELIMINARY)
Product Summary
The ESL Supervised Commercial Wireless Smoke Detector is UL Listed (UL 268) for use in commercial applications. The unit
combines a photoelectric smoke detector with an integrated fixed 135°F temperature and rate-of-rise heat detector, and a
Learn Mode transmitter for use with compatible wireless control panels (see “Specifications” on back page).
Detector Operation
Under normal non-alarm conditions, the detector LED (light-emitting diode) flashes once every nine seconds while monitor-
ing the surrounding conditions. The detector transmits a supervisory signal every 64 minutes indicating its status, which the
panel receives and processes accordingly.
In an alarm condition due to smoke or heat, the LED changes from flashing to on and the built-in sounder emits a temporal 3
pattern (a repeated series of three beeps followed by a short pause). The detector also transmits an alarm signal, which the
panel receives and processes accordingly.
A built-in tamper switch activates whenever the detector is removed from its mounting base, causing the detector to transmit
a tamper signal which the panel receives and processes accordingly.
The detector is powered by two 3-volt lithium batteries (included). When the battery voltage gets low, the detector transmits
a low battery signal which the panel receives and processes accordingly. If the batteries are not replaced within seven days,
the detector’s built-in sounder emits a short beep or chirp every 45 seconds.
The detector also includes self-diagnostics, automatically adjusting its sensitivity accordingly to reduce the number of
detector cleanings. When cleaning becomes necessary, the detector has a field-replaceable optical chamber.
General Guidelines
•
Before mounting detectors, program (learn) them into panel memory and perform a sensor test from the detector’s
intended location, to ensure good RF communication to the panel.
•
Locate the detector in environmentally controlled areas where the temperature range is between 40° and 100°F (4.4° and
37.8°C) and the humidity is between 0 and 90% non-condensing.
•
Locate detectors away from ventilation sources that can prevent smoke from reaching the detector.
•
Locate ceiling mounted detectors in the center of the room or hallway, at least 4 inches (10cm) away from any walls or
partitions.
•
Locate wall mounted detectors so the top of the detector is 4 to 12 inches (10 to 31cm) below the ceiling.
•
In rooms with sloped, peaked, or gabled ceilings, locate detectors 3 feet (.9 meters) down or away from the highest point
of the ceiling.
•
When mounting to suspended ceiling tile, the tile must be secured with the appropriate fastener to prevent tile removal.
Note:
Do not mount the detector to the metal runners of suspended ceiling grids. The metal runners can draw the magnet’s field away
from the detector’s reed switch, causing a false tamper alarm
