1000 ohm.
Stand-by Specifications:
Stand-by Batteries Stand-by Time Total Amp/Minutes Alarm Output Current Aux. Output
24VDC/7AH 24 Hours 6.5 amp/5 minutes ---
24VDC/12AH
(use two (2) 12VDC batteries in series)
24 Hours 6.5 amp/5 minutes 50mA
24VDC/36AH 24 Hours 6.5 amp/5 minutes 1 amp
Note: Unit is equipped with two (2) 1 amp max. auxiliary outputs: “AUX1” will automatically disconnect when
AC is lost. “AUX2” will remain battery backed up during power outage. For loads connected to “AUX2” please,
refer to battery “Stand-by Specifications” above for ratings. When loads are connected to the “AUX1” and or
“AUX2” outputs during alarm condition, the remaining outputs may, not exceed 6.5 amp total alarm current.
(example: AUX1 = 1 amp, AUX2 = 1 amp, outputs up to 6.5 amp).
Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/
ANSI, and with all local codes and authorities having jurisdiction.
Product is intended for indoor dry use only.

1. Mount the unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the
enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s
upper keyholes over the two upper screws; level and secure. Mark the position of the lower two holes. Remove the
enclosure. Drill the lower holes and install two fasteners. Place the enclosure’s upper keyholes over the two upper
screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 8).
Secure enclosure to earth ground (Fig. 1, pg. 3). Small terminal block wire gauges range from
16 AWG to 24 AWG, all others range from 14 AWG to 24 AWG.
2. Connect the line (L) and neutral (N) terminals to a separate unswitched AC circuit (120VAC, 60Hz)
dedicated to the Fire Alarm System.
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Connect battery to the terminals marked [+ BAT -- ] on the Power Supply Board (battery leads included).
Use two (2) 12VDC batteries connected in series.
5. Set output selection switches marked [OUT1 through OUT4] to follow corresponding
input [IN1 & IN2]
and desired output signal type (Output Programming Selection Table, pg. 4).
