Bosch Security Systems, Inc.
Use a UL Listed 18 V Class 2 transformer (22 VAC, VA 50/60 Hz), or the
EZPS Power Supply
In an NF A2P certified installation, use the EZPS power supply delivered
with the panel
1.4 A (AC power and standby battery; intrusion applications only).
With a 7.0 Ah battery, the following current draws apply to all outputs and
devices connected to the system:
– Up to 170 mA for 24 hr for fire and combined fire/burglary
applications
– Up to 1.2 A for other applications
12 VDC, 1.0 A maximum. Includes 110 mA for each control center
connected to the system, and up to 400 mA for the programmable outputs.
85 mA standby; 160 mA alarm with all outputs activated
12 VDC nominal (11.2 VDC to 12.3 VDC)
The control panel stops processing point faults when the voltage drops
below 9.5 VDC.
D126 (7 Ah) or D1218 (18 Ah) sealed, lead acid rechargeable
1.7 A maximum recharging current
Low battery condition occurs when battery drops below 12 VDC
If AC power fails and the battery drops below 9.5 VDC, the control panel
stops processing point faults. Disconnect the battery under these
conditions.
Maximum auxiliary current to recharge standby battery within 72 hours:
– 12 V, 7 Ah Battery: 400 mA
– 12 V, 18 Ah Battery: 900 mA
In an NF A2P certified installation, use a battery Yuasa NP17-12IFR
