Description

Designed for use with either standard Fire Safety systems or other commercially available fire alarm systems, the DT-135CL, DT-200CL, DT-135CS, DT-200CS, DT-135WP and DT-200WP Thermal Fire Detectors are of the rate compensation/fixed temperature type and are In all models the detector element is self-restoring after operation and is supplied in ratings of 135°F and 200°F. While UL recommends the Thermal Detector be used to protect a maximum of 2,500 square feet, job conditions and engineering judgment often dictate closer spacing to provide faster detection. The Models DT-135CL and DT-200CL are used with Fire Safety low voltage systems where it is desirable to provide visual identification of an operated detector by means of an internally mounted incandescent lamp. These models lock in upon alarm and must be reset at the control panel. The Models DT-135CS, DT-135WP, DT-200WP and DT-200CS can be used with any fire alarm circuit of any manufacturer using open circuit direct shorting type units. These units do not contain a series-connected resistor or an indicator lamp and do not lock in upon alarm. Contact ratings are 6-125 VAC, 5 A; 6-25 VDC, 1 A125VDC, 0.5 A. The DT 135WP and DT-200WP are both UL listed and US Coast Guard approved as weatherproof. They are furnished with leads through a 1/2″ NPT hub that screws into a standard W.P. junction box cover with an epoxy-coated shell. UL and ULC Listed*, and NYMEA, CSFM and City of Chicago Approved*. *Pending Adapter Plate only.
