If the Verify Relay is configured for “Non-Latching” then it will 
reset to normal when the detector no longer sees a verified fire for 
a period of time (factory default is 3 seconds). 

Pins on the "J3" connector labeled “Verify In” and “Verify Out” 
provide connections for Normally Open contacts on the -HE1 and 
-HE3 models or Normally Closed contacts on the -HE2 and -HE4 
models.

2.7.4   Aux. Relay 

The Aux. Relay is energized whenever the detector fails the UV 
self test.  This fault indicates degradation in the detectors ability to 
“see” a fire.  Normally, cleaning the lens will clear this fault.  This 
condition normally occurs when there is an oily lens or a 
malfunctioning UV sensor.  The Pins on the "J3" connector (see 
section on Connectors) labeled “Aux In” and “Aux Out” provide 
connections for a Normally Open contact on the -HE2 and -HE3 
models or a Normally Closed contact on the -HE1 and -HE4 
models. 

3.  Installation 

3.1  Housing and Conduit 

3.1.1  Mounting the Housing 

The housing is mounted by using the two .3” diameter holes 
located in ears on the back of the housing.  The two conduit holes 
located on the side of the housing are not to be used for 
mounting.  The detector should be mounted securely to a flat 
surface.  The mounting location must be strong enough to support 
the detectors weight.  Although the detector is not vibration 
sensitive the detector should not be exposed to excessive 
vibration.  The detector has been tested to .022” displacement, 10 
Hz to 30 Hz sweep cycled at 2 cpm for 4 hours. 

3.1.2  Installing the Conduit and Wiring 

Mount a “Seal Off” at the housing into the 3/4” NPT conduit 
opening(s) located on either side of the housing.  Connect the 
conduit to the “Seal Off”.  If one of the conduit openings is not 
used insert a sealing plug into the unused opening.  Run the wires 
through the conduit, “Seal Off”, and into the housing.  The ends of
