CAUTION

Dust  covers  provide  limited  protection  against  airborne 

dust  particles  during  shipping.  Dust  covers  must  be 

removed  before  the  sensors  can  sense  smoke.  Remove 

sensors prior to heavy remodeling or construction.

Testing

Before testing, notify the proper authorities that the system 

is undergoing maintenance, and will temporarily be out of 

service. Disable the system to prevent unwanted alarms.

All  sensors  must  be  tested  after  installation  and  periodi-

cally thereafter. Testing methods must satisfy the Authority 

Having  Jurisdiction  (AHJ).  Sensors  offer  maximum  per-

formance when tested and maintained in compliance with 

CAN/ULC S536. 

The sensor can be tested in the following ways:

A. Functional:  Magnet  Test  (P/N  M02-04-01  or  M02-09-

00) 

  This sensor can be functionally tested with a test mag-

net. The test magnet electronically simulates smoke in 

the sensing chamber, testing the sensor electronics and 

connections to the control panel.

  1. Hold  the  test  magnet  in  the  magnet  test  area  as

shown in Figure 3.

  2. The sensor should alarm the panel.

    Two LEDs on the sensor are controlled by the panel 

to indicate sensor status. Coded signals, transmitted 

from  the  panel,  can  cause  the  LEDs  to  blink,  latch 

on, or latch off. Refer to the control panel technical 

documentation for sensor LED status operation and 

expected delay to alarm.

B. Smoke  Entry:  Aerosol  Generator  (Gemini  501)         

            

The GEMINI model 501 aerosol generator can be used 

for smoke entry testing. Set the generator to represent 

4%/ft. to 5%/ft. obstruction as described in the GEMINI 

501  manual.  Using  the  bowl  shaped  applicator,  apply 

aerosol until the panel alarms.

 

A  sensor  that  fails  any  of  these  tests  should  be  cleaned 

as  described  under 

CLEANING

,  and  retested.  If  the  

sensor  fails  after  cleaning,  it  must  be  replaced  and 

returned for repair.

When  testing  is  complete,  restore  the  system  to  nor-

mal  operation  and  notify  the  proper  authorities  that  the  

system is back in operation.

Do not loop wire under terminal 1 or 2. Break 

wire run to provide supervision of connection.
