NOTES
Note 1: The Total calculation does not include the Isolator devices or accessory bases.
Note 2: If you use door holders, you do not need to calculate the door holder current for the alarm/battery standby, because the power is
removed during that time. During normal operation, the door holders draw current and must be included in the 2.5A total alarm current (1.0A
for all other conditions that can be drawn from the panel.
Note 3: Use the next size battery with capacity greater than required. ABD-RT2F draws a maximum of 500mA from Auxiliary power only
when you use the test feature. This should be considered when you determine the auxiliary power capacity but not calculated into current
requirements for day-to-day operation. The ASD-PL2FR is sold separately from the DNR. Current draw for the DNR + ASD-PL2FR is
calculated by increasing the “Number of Devices” column for each ASD-PL2FR used with a DNR.
Note 4: The DNR housing does not include a Relay circuit board. If a relay is needed, be sure to add one to the AOM-2RF & ASD-PL2FR
“Number of Devices” column for each DNR used for correct current calculations.
Note 5: The FACP supports only 5 devices w/LED’s ON. This current draw has been added to the panels alarm current.
Note 6: UL 268 7th Edition Sensitivity Level Requirements:
The models: ASD-PL3/-IV, ASD-PL3R/-IV, ASD-PTL3/-IV, detectors must be programmed with the following Sensitivity Levels to be
compliant with the UL 268 7th Edition requirements (3% is the Default).
- 1% and 1.5% for Special Applications
- 2%, 2.5% and 3% for Open Area Protection
