Testing the Sensor
Detectors must be tested after installation and following periodic main-
tenance. The Model #SD4-SS may be tested as follows:
A. Test Switch
1. A recessed test switch is located on the detector housing
(see Figure 6).
2. Push and hold the recessed test switch for a minimum of 5 seconds.
Use a small screwdriver or Allen key with maximum diameter of
0.18 inch (the detector will trigger and then the smoke detector will
go into alarm thus sending a transmitting signal to the receiver. If
the tool is removed from the recessed switch the sounder will shut
off)
If the detector is within the listed sensitivity limits, the LED on the
detector should blink once per second and the horn should sound with-
in 3 seconds.
