8.2 Testing Procedures for the DL1 Dialer Module
Every Six months (or as required by the Authority Having Jurisdiction):
•
Verify that the dialer module is connected to two separate phone lines.
•
Activate an alarm initiating device and verify the alarm is received at the Central Monitoring Station
(CMS). Restore System to normal.
•
Verify that failure of the primary signal path (phone line connected to J1) results in a trouble signal
being transmitted via the secondary signal path (phone line connected to J2) within 4 minutes.
• Verify that failure of the secondary signal path (phone line connected to J2) results in a trouble signal
being transmitted via the primary signal path (phone line connected to J1) within 4 minutes.
8.3 Testing Procedures for Compatible 2-Wire Smoke Detectors
EDWARDS 2420
m Functional Test: Hold a magnet next to the alarm LED. The detector should alarm within 5 seconds.
m
Cleaning: To clean the ion chamber, disable the zone using the ENABLE/DISABLE switch to prevent
accidental alarm. Remove the detector from its base. Remove the grill. Place the vacuum cleaner
nozzle over the chamber and remove dust. Reinsert the grill by aligning tabs on the grill with slots on
the housing. Press the grill into the housing and turn clockwise until grill locks into position.
EDWARDS 2430
m
Functional test: Insert the long end of the calibrated test probe (P/N 6278-001A) into the oblong
opening on top of detector grill. The detector should alarm within 10 seconds. Insert the short end of
the calibrated test probe into the oblong opening on top of the detector grill. The detector should NOT
alarm within 10 seconds. If an alarm occurs, clean or replace the detector.
m
Cleaning: To clean photo chamber, disable the zone using the ENABLE/DISABLE switch to prevent
accidental alarm. Remove the detector from its base. Remove the grill. Vacuum dust and foreign
material from the optic ramp area. Remove the bug screen from the grill. Wash the bug screen and
grill in water and air dry. Reinsert the screen into the grill. Reinsert the grill by aligning the arrow on the
rim of the grill with the LED on the housing and turn clockwise until the grill locks into position.
CAUTION
If the grill is removed while the detector is in its base, the detector will generate an
alarm.
NOTE
Aerosol test sprays are NOT recommended due to possible interaction with composite
detector housings.
