Attaching and Removing
Attaching
Attach the mounting base to the ceiling using
the screws provided.
Attach the EL-2603NA to its mounting base.
To do so, line up the raised tab on the lip of
the detector with the slot/arrow on the lip of
the mounting base. Insert the detector into
the base and turn clockwise approximately 15
degrees. It should snap firmly into place.
,
The Detector cannot be attached
to the mounting base if no
batteries are installed because of
the chance of false alarms from
the detector:
LED
The LED on the Detector indicates the status
of the alarm as follows:
Flashing – Flashes every 9 seconds to
indicate normal operation.
ON – detects smoke.
OFF – Trouble or maintenance is required.
Removing
Remove the red plastic dust cover from the detector. The detector is
shipped with a dust cover for protection on construction sites with dusty
environments.
Remove the EL-2603NA smoke detector from its mounting base. To do
so, grasp the detector and turn it counterclockwise approximately 15
degrees. The detector should snap off of the mounting base. To remove
the detector from the mounting base when the detector/base lock is used,
insert a small screwdriver into the locking tab slot on the side of the base
and press in while simultaneously turning the detector counterclockwise
15 degrees. See Figure 2
When to Replace the Batteries
The detector requires two 3V lithium A batteries as listed on the battery
compartment cover, with the exception of the Energizer brand
batteries. The required batteries are available where other batteries are
sold. Battery life is a minimum of 1 year and varies depending on how
often an alarm occurs. When the batteries are low, the detector
extinguishes its LED and chirps every 30 seconds until the batteries
are replaced. The sounder can be silenced for 24 hours by pushing the
Test/Silence button.
Replacing the Batteries
Remove the detector from the mounting base.
Slide the battery compartment cover away from the detector, unsnap it
and lift it off. See Figure 3.
Remove the batteries and dispose of them properly.
Observing correct polarity insert two new CR123 Lithium Battery
(Duracell DL123A, Sanyo and Panasonic CR123A) into the battery
compartment and replace the cover.
Perform Testing and Registration (See Testing and Registration).
Test the detector. See Smoke Testing the Detector.
