l
24hour Test Transmission over phone line (PSTN) and LE4020/LE4020CF must be enabled.

On the Subscribers’ Unit, program PGM1 for PC1616/PC1832/PC1864 as System Event (Section [009]
as type 10; Section [501] Fire Event option 2 ON). An alternate option is to program PGM1 as Zone
Follower (Section [009] = 29) and assign Fire Zone to PGM1 in Section [551]. Ensure Bit 3 is on in
[501]. In this case, a restored fire alarm condition does not require the DSC control panel to be reset.
For PC4020, program PGM1 as type 49 Steady Fire ([00070049]).
l
Dry contact outputs from ULC Listed Fire Alarm Control Unit must be connected to zone inputs on the
ULC Listed DSC subscribers' Unit Fire.
