Programming 

For multiplex programming, refer to the 

D7024 FACP 

Operation and Installation Guide

 (P/N: 31499)

 

or the 

DS9400M Reference Guide

 (P/N: 44578). 

7.0 Testing 

Test detection devices immediately after installation. 
Test the D7050DH according to NFPA Chapter 7-1.6.2 
(1999) or more often as required by local code. 

7.1 Operational 

Testing 

 

 

Notify all concerned parties before and 
after completing maintenance on or testing 
the  
fire alarm system. 

1.

 

Apply power to the system and check for alarms. 

2.

 

If a D7050DH is in alarm, shut down the system. 

3.

 

Remove the D7050DH and recheck for proper 
wiring. If the problems persist, replace the affected 
D7050DH or exchange it with a known good 
detector. This determines if the problem is caused 
by the D7050DH. 

4.

 

When the system is free of alarms, check each 
D7050DH to ensure the red LED indicator on the 
head flashes. This confirms the detector is 
operating properly. 

5.

 

Test each D7050DH to ensure it causes a control 
panel alarm.  

6.

 

Alarm the D7050DH by doing one of the 
following: 
a.

 

Place a magnet horizontally against the recess 
in the duct cover, centering it over the “T” 
marked on the head to activate an internal 
reed switch.  

b.

 

Remove the duct cover and use a UL Listed 
aerosol smoke detector tester such as the 
Home   Safeguard Industries’ 25S to simulate 
an alarm. Follow the instructions included in 
the aerosol smoke detector tester. 

7.

 

When a D7050DH alarms, the red LED indicator 
on the head flashes at least once per second. Clear 
the alarm by initiating a system reset before 
proceeding to the next detector. 

7.2 Sensitivity 

Testing 

 

Calibration is important in determining a 
detector’s continued operation. Depending 
on local regulations, calibration testing 
might be required more than once a year. 
According to NFPA72, perform a 
Calibration Test at installation and every 
other year thereafter. Perform a Functional 
Test monthly. 

Test the D7050DH’s sensitivity to meet NFPA 72 
requirements by conducting a Magnet Test (refer to 

Section 7.3 Magnet Test

). You can also test sensitivity by 

measuring the calibration voltage pins with D1005 Test 
Cable, D344-RL, or D344-RT (refer to 

Section 7.4 

Voltage Measurement Test

). Calibration can be quickly 

determined by visually inspecting the D7050DH’s LED 
(refer to 

Section 7.2.2 Visual Check

). These tests confirm 

whether or not the detector is within its factory marked 
calibration range. 

7.2.1 Sensitivity 

Test 

The control panel constantly monitors the D7050DH. 
If the detector exceeds the limits of the sensitivity 
thresholds, the control panel reports the detector in 
question and generates a fault condition. 

7.2.2 Visual 

Check 

The D7050DH includes the Chamber Check 
Automatic Trouble Indication that allows it to 
automatically show if its calibration is out of the 
factory-listed range. You can meet the NFPA guidelines 
for sensitivity testing by visually inspecting the 
D7050DH and checking the Alarm LED flash rate.   

If the calibration is out of range during power up or 
longer than 24 h, the Alarm LED double flashes. This 
LED single flashes when the detector is operating 
normally. 

 

Visually check all detectors before 
disconnecting the multiplex bus. 
Disconnecting the bus erases the 
calibration indication. If the detector was 
disconnected or the control panel lost 
power within the  
last 24 h, perform a Magnet Test or Voltage 
Measurement Test to confirm sensitivity.
