Low Temperature Detector (EL-2663)

The EL‐2663 is a wireless low temperature detector designed for use with Electronics Line 3000's
supervised wireless range of receivers. The EL‐2663 includes a thermostat that causes the
transmitter to send an alarm signal when the temperature falls to approximately 5ºC (41ºF).

Mounting Location

Consider the following when choosing a mounting location:

Do not locate the detector near heaters or boilers that may stay warm long after the
temperature has dropped in other parts of the premises.

Mount the detector in a location that is likely to get cold first when the temperature
drops.

Try to locate the detector in a location where there is good air circulation.
Installation Instructions
1. To open the housing, insert a small screwdriver at the bottom of the unit between the
front and back cover and twist the screwdriver to release the cover.
2. Remove the divider separating the battery from the contacts on the battery holder. When
you apply power and the Tamper switch is open, the EL‐2663 enters Test mode during
which a transmission is sent every few seconds. You can terminate Test mode by closing
the Tamper switch. Test mode is automatically terminated after approximately five
minutes.
Due to the occurrence of voltage delay in lithium batteries that have been in storage, the
batteries may initially appear to be dead. In this case, leave the unit in Test mode for a few
minutes until the battery voltage level is stabilized.
3. While the EL‐2663 is in Test mode, set the receiver to Registration mode and make sure
that the transmitter's LED indicator lights up at least twice. After registration,
momentarily close the Tamper switch to terminate Test mode. Write the number of the
zone and the transmitter number (where applicable) on the sticker provided. Affix the
sticker inside the front cover for future reference. Note: Alternatively, the EL‐2663 can be
registered to the receiver by manually entering the transmitterʹs serial number.
