This input is used to invoke the push-to-test alarm, alarm memory indication,
and the timer mode. This input has an internal pull-down.
This bidirectional pin provides the capability to interconnect many detectors in a
single system. This pin has an internal pull-down.
This pin selects the NFPA72 horn tone (high) or the 2/3 duty cycle continuous
tone (low).
This pin is strobed on with the internal clock in timer mode. A resistor
connected to this pin is used to modify the detector sensitivity for the timer
period.
Open drain NMOS output used to drive a visible LED.
Connect to the positive supply voltage.
A resistor connected between this pin and V
Usually connected to the feedback electrode through a current limiting resistor.
If not used, this pin must be connected to V
Connect to the negative supply voltage.
This pin is connected to the metal electrode of a piezoelectric transducer.
HS is a complementary output to HB and connects to the ceramic electrode of
the piezoelectric transducer.
A capacitor connected between this pin and V
This pin can be used to modify the set point for the smoke comparator by use of
external resistors to V
Output of the guard amplifier.
Connect to the collector electrode (CEV) of the ion smoke chamber.
Output of the guard amplifier.
