Description
New Series photoelectric and photoelectric/ thermal smoke
detectors represent a significant advancement in conventional
detection, incorporating three key features: installation ease,
intelligence, and instant inspection.
Installation ease: The New Series redefines installation ease
with its plug-in design. This allows an installer to pre-wire the
bases included with the heads. The large wire-entry port and
in-line terminals provide ample room for neatly routing the
wiring inside the base. The base accommodates a variety of
backbox mounting methods, as well as direct mounting with
drywall anchors. To complete the installation, New Series
heads plug into the base with a simple Stop-Drop ’N Lock
action.
Intelligence: New Series detectors offer a number of intelligent features to simplify testing and maintenance. Drift
compensation and smoothing algorithms, to minimize
nuisance alarms, are standard in the New Series. When
connected to an AUTOPULSE 542R/542D Control Panel,
two-wire New Series detectors are capable of generating a
remote maintenance signal when they need cleaning. This
signal is indicated by LEDs located at the AUTOPULSE
542R/542D Control Panel.
Storage Temperature Range: –4 °F to +158 °F (–20 °C to
+70 °C).
Operating Humidity Range: 10% – 95% RH, non-condensing.
Thermal Sensor: 135 °F (57 °C) fixed (models 2WT-B,
4WT-B).
Freeze Trouble: 41 °F (5 °C) (models 2WT-B and 4WT-B).
Sensitivity: 2.5%/ft (0.762%/meter) nominal.
Input Terminals: Utilize 14 to 22 AWG wire.
Dimensions (including base): 5.3 in. (135 mm) diameter,
2.0 in. (51 mm) high.
Weight: 6.3 oz (178.6 grams).
Mounting Options: 3.5 in. (89 mm) octagonal backbox; 4 in.
(102 mm) octagonal backbox; single-gang backbox; 4 in.
(102 mm) square backbox with a plaster ring; or direct mount
to ceiling.
Instant inspection: The New Series provides wide-angle red
and green LED indicators for instant inspection of detector
condition. The LEDs indicate: normal standby, out-of-sensitivity, alarm, or freeze trouble conditions. The “EZ Walk” loop test
feature is available on two-wire New Series detectors when
connected to an AUTOPULSE 542R/542D Control Panel. The
“EZ Walk” feature verifies the initiating loop wiring by providing LED status indication at each detector.
