With the Standby Switch locked down, the panel deactivates the external relay outputs, suppresses reports, and disables all
arming functions.
Note: Lock the Standby Switch down to program the panel locally, from the keypad, or the D5200.
Releasing the Standby Switch from the closed position resets the panel. The panel resets all its timers and counters, and clears
all buffers. If the panel is armed, releasing the standby switch causes the panel to disarm.
3.7
Install Detection Devices, Keypads, and Bells
3.7.1
No Connection to the Panel Yet
Install and wire detection devices, keypads, and indicating devices (bells, sirens, or strobes for example) at their locations
throughout the premises.
Do not
make the connections at the panel end of the wiring yet.
3.7.2
Number of Sensors
When using Point 1 as a fire point, the number of detection devices you can connect to its sensor loop is limited. See Point 1
in Section 6.1 Point 1 (1+ and 1-) on page 25.
The number of detection devices you can connect to the sensor loops for Points 2 to 6 is limited only by the resistance on the
loop. Resistance must be less than 100
Ω
with the detection devices connected.
3.8
Continue Connections to the Panel
3.8.1
Power Down First
Unplug the transformer and disconnect the battery to make the remaining connections to the panel.
3.8.2
Alarm Output (+Alrm-)
The Alarm Output terminals provide a 10.2 VDC to 13.9 VDC output when activated.
The positive (+) terminal provides
steady positive output
. The negative (-) terminal provides a pulsed or steady negative output as programmed.
Use this power for bells, siren drivers, piezo fire sounders, electronic horns, or other devices.
3.8.2.1
Available Power
The panel combines power produced by the power supply with power from the secondary power source (the battery) to
produce a total of 1.35 A of
alarm
power at the Alarm Output terminals.
3.8.2.2 Fire System Power Formula
To calculate the current available at the Alarm Output terminals for fire and combined fire/burglary systems:
1.
Add together the current draws for all devices connected to the negative alarm output terminal. This total is the
current required for the
N
ormal
S
tandby
C
ondition (NSC). This total must be less than 140 mA.
2.
Subtract the NSC current required calculated in step 1 from the Primary Alarm Current, 860 mA. The
difference is the Alarm Current available for the Alarm Output terminals.
In formula format:
Primary Alarm Current - NSC current required = Alarm current available
3.9
Keypads (Data and + Aux -)
You can connect a combination of up to eight keypads and two types of point expanders (wired or RF) to the panel. Four
keypads with expanders can have points assigned to them.
The installation sheet packed with each keypad contains mounting instructions. Wire keypads and other devices to the panel
in parallel as shown in Figure 4 on page 18.
IMPORTANT
You must use a minimum of 5 ft. (1.5 m) of wire (22 AWG / 0.8 mm) when connecting the keypad to the panel. A
short on the positive Aux terminal within 5 ft. (1.5 m) of the panel prevents the panel from operating correctly.
Maximum wire length for all devices connected to Data and Aux (+,-) terminals combined is 500 ft. (152.4 m [22 AWG/
0.8 m]).
Extra power needed for more keypads.
Review Power Outputs in Section 4.3, Power Outputs on page 20 to determine the
total power output requirements for your system. Instructions for using stand-alone power supplies are included.
