Technical Handbook
Note 1:
+24 VDC Nominal = Controller Input (18 to 32 VDC) 1.8 VDC (the max voltage drop in the TPPL).
Note 2:
Alarm Terminals 13, 19, 20, and 21 can 24 VDC at 28 W combined this 28 W can instead be used to
increase the power available to field sensors if external audible and visible alarms are not connected. e.g. the 8 sensor
channels would normally have
W of combined available power, but this can be increased to 68.8 W if terminals 13
21 are unused.
Note 3:
You must supply sensors with external power if more than 40 / 68 W total power is required (See Note 2).
Note 4:
Maximum R
loop
resistance for a remote reset/inhibit switch is 18
Ω

Note 5:
RLY1 or RLY2 should be configured as "system inhibit relay"
