- Connect ground wire from door hinge to earth ground using
16 AWG, green jacketed, solid-conductor wire
GENERAL INFORMATION
- All outputs are power limited
- If programmed for EOL or Supervised loop, the 2.2K ohm EOL
resistor (Model 9.X, 2.2K) must be at end of circuit
- Loop 8 can be used as standard loop or used for switched 10-
12.5 VDC at 50 mA for 2-wire powered devices. Loop 8 can
support up to 10 BRK Model 2400 2-wire smoke detectors.
- Loop voltages:
Loops 1 - 8
0 - 2.5 VDC = short
2.5 - 8.5 VDC = normal
8.6 - 15 VDC = open
- Install transformer on unswitched power receptacle
- Only use 12 VDC, 6.5 AH sealed lead-acid battery
POWER SUPPLY INFORMATION
- Replace battery every 3 - 5 years with C&K Model 1265
- Standby time with 1 keypad is 16 hours at 250 mA
- Power demand for AUX POWER, keypads, and sounders
not to exceed maximum ratings
