Overview
The RF280E Series Photoelectric Smoke Detectors are
open-area wireless smoke detectors designed for use
with commercial fire protective signaling and household
fire warning systems.
For commercial and industrial installations, allow
spacing of 30 ft (9 m) between detectors.
An Alarm and Test LED flashes approximately every
26 sec to verify the detector has battery power and the
smoke sampling circuitry is functioning. The LED
flashes every 0.5 sec in an alarm, allowing the user to
verify individual detector alarms. The detector
automatically resets after 3 min if the alarm condition
no longer exists.
The detector can be manually reset by pressing the Test
button. If there is an alarm after the Test button is
pressed, the detector re-alarms in 20 to 30 sec. After the
alarm condition clears, the control panel alarm can be
cleared by a control panel reset command.
Supervision is provided by transmitting a low power
level signal to the receiver every 13 min if there is no
other activity. All transmissions from the RF280E Series
send battery status information to the control panel.

Mounting
The detector's maximum wireless range in
open air is approximately 984 ft (300 m). In
normal residential or commercial
applications, keep the detector within 328 ft
(100 m) of the control panel receiver it is
assigned to. Temporarily mount the detector
using double-sided tape, and test it from the
desired location before permanently
mounting it.
1. Remove the detector's dust cover. You can replace
the dust cover during construction periods, but
remove it when the alarm system is enabled.
2. The mounting plate has a base locking tab that, if
used, requires you to press the locking tab towards
the mounting surface to release the detector. If you
do not want the Lock-In feature, do not make
changes to the mounting plate. Use the Lock-In
feature by modifying the base locking tab as shown
in Figure 1.

3. Remove the detector from the mounting plate by
twisting the base counterclockwise.
4. Install the mounting plate in the desired location,
and do not attach the detector to the mounting plate
at this time.
5. Install the two lithium batteries (Item 1 in Figure 2)
in the detector's base and observe the polarity. These
batteries are supplied in a separate package.

6. A two-part sticker on the detector's base (Item 2 in
Figure 2) contains the nine-digit programming serial
number. Remove one of the stickers and store it in a
safe place. You need the number to program the
detector from the control panel.
7.
Connect the detector to the mounting plate and twist
it clockwise.
