Description
The D7050DH (
Figure 1)
is Underwriters Laboratories,
Inc. (UL) Listed and requires a D343 Duct Detector
Housing. Use this detector with the D7024 or a
DS9400M that includes a D7039 or DS9431 Multiplex
Expansion Module.
An LED indicator on the head flashes every 3 to 8 sec
to ensure the D7050DH has power and the smoke
sampling circuitry functions. This LED flashes at least
once each second during an alarm confirming
individual detector alarms. The D7050DH
automatically resets after the alarm condition clears.
