Ion detector— limit of thirty per zone. (See
Spec Sheet Catalog No. 6119.)
Dl-3IS
This ion detector is for intrinsically safe
applications when used with the ZS-30
module with diode shunt barrier. There is a
limit of ten detectors per zone circuit. (See
Spec Sheet Catalog No. 6119.)
DT-C Series
The DT-135CS and DT-200CS thermal
detectors are the rate compensated type
available in 135° F and 200° F settings. The
DT-135CL and the DT-200CL are identical to
CS versions, except that they have an
internal alarm indicating lamp. There is a
practical limit only to the number per zone.
(See Spec Sheet Catalog No. 6131.)
DT-11 Thermal Detector
The DT-11 is a thermal detector for use in
open areas. It uses the DB-11 low profile
surface mounting base or the DB-3S base
with the DB-ADPT adapter. (See Spec
Sheet Catalog No. 6174.)
DT-135/200 WP
This weatherproof thermal detector has a
rate compensated principal available in
either a 135° F or 200° F setting. The detec-
tor is epoxy coated and mounts to a weath-
erproof box for approved use in wet or
unsheltered locations. (See Spec Sheet
Catalog No. 6127.)
DT-140/190 EP
This explosionproof thermal detector has a
rate compensated principle available in
either a 140° F and 190° F setting. It should
be used in hazardous areas requiring
explosionproof devices. The detector
mounts to an approved explosionproof
junction box. (See Spec Sheet Catalog No.
6128.)
PE-11 Photoelectric Detector
The PE-11 is a photoelectric detector that
responds to a wide range of both flaming
and smoldering fire conditions. It uses the
DB-11 low profile surface mounting base,
the DB-3S base with the DB-ADPT adapter,
or the AD-11P/PR air duct housing. (See
Spec Sheet Catalog No. 6173.)
PE-11T Photoelectric Detector with
Heat Sensor
The PE-11T is a photoelectric detector with
heat sensor that responds to a wide range
of both flaming and smoldering fire condi-
tions. It uses the DB-11 low profile surface
mounting base or the DB-3S base with the
DB-ADPT adapter. (See Spec Sheet Cata-
log No. 6173.)
