Description

The Firelite SD300(A) combines a photoelectronic smoke sensing chamber with addressable communications. Also, The detector uses an optical smoke sensing chamber and transmits information through a communication line to a control panel. Besides, two rotary dial-decade switches allow the setting of the detector’s address. Model SD300T(A) has the same specifications as Firelite SD300(A) but also features a built-in, restorable, fixed-temperature (135°F), thermal detection unit.

An LED on the detector provides an indication of the detector’s status. Furthermore, coded signals, transmitted from the panel, control the LED to blink, latch on, or latch off. In normal operation, the detector LED blinks in standby as well as latches on in alarm. A recessed “push to test” switch allows testing of the detector’s alarm capability with a small rod or screwdriver. The detector provides a test module socket for testing the detector’s sensitivity with the MOD400R test module.

In addition, both models include a plug-in screw terminal block and a mounting bracket. The terminal block allows the detector to be disconnected from the system without loss of power to the remaining loop. The mounting bracket includes a tamper-resistant capability that, when enabled, prevents detector removal from the base without the use of a tool.
