Using a Supplementary Power Supply to Power Additional Keypads
The control provides 1 amp of auxiliary standby power for powering keypads and
other devices from the auxiliary power output. Aside from this, the control can
support up to 16 peripheral devices (keypads, RF receivers, relay modules, etc.).
The backup battery will supply power to these devices in the event that AC power
is lost (a 1 amp load requires a 34.4 AH battery (see the
POWERING THE
SYSTEM section for more information)).
When the control’s auxiliary power load for all devices exceeds 1 amp, you can
power additional keypads from a regulated, 12VDC power supply (e.g., Alarm-
Saf model AS/PS5-BFS-12-UL). Use a UL Listed, battery-backed supply for UL
installations.
Connect the additional keypads as shown in Figure 5, using the keypad wire
colors shown. Be sure to observe the current ratings for the power supply used.
1.
Make connections directly to the screw terminals as shown in Figure 5.
Make no connection to the keypad blue wire (if present).
2.
Be sure to connect the negative (–) terminal on the Power Supply unit to
terminal 12 (AUX – ) on the control.
