Remote Station Applications
4.12 Remote Station Applications
4.12.1 Keltron Model 3158 Installation
The fire alarm control panel is compatible with the Keltron Model 3158, used for direct connection to a Keltron receiver. The Keltron
3158 reports alarms, supervisories, and troubles. The Keltron 3158 is intended for connection to a polarity reversal circuit of a remote
station receiving unit with compatible ratings.
Refer to the following steps to connect the Keltron 3158 to the control panel and the Keltron 3158 instructions for complete information.
1.
Wire the Keltron 3158 to the fire alarm control panel as shown in the connection list and Figure 4.27.
2.
Wire the Keltron 3158 within 20 feet of the control panel. Wiring must be enclosed in conduit.
3.
Program the fire alarm control panel Relay 2 for alarm.
4.
Program the NAC circuit 2 for alarm and program the NAC circuit 1 for supervisory non-latching.
NOTE: You must program the NACs for continuous and non-silencing.
Note 1: The Keltron 3158 is
used for connections to a
polarityreversal circuit of a
remote station, receiving unit
with compatible ratings.
4.12.2 City Box Connection Installation Using the 5220 Module
This section describes the procedure to connect the control panel to a Municipal Fire Alarm Box or "City Box" as required by NFPA 72
Auxiliary Protected Fire Alarm Systems for fire alarm service. The City (master) Box is an enclosure that contains a manually operated
transmitter that is used to send an alarm to the Municipal Communication Center. The Municipal Communication Center houses the cen-
tral operating part of the fire alarm system.
•
City Box Standby Current: 0 (Notification supervision current accounted for in control panel draw.)
•
Alarm Current: 1 Amp for 1 second
The maximum coil and wire resistance (combined) must not exceed 30 ohms. To install the 5220 Module to the City Box connection,
refer to the following:
1.
Locate one of the knockouts on the right side of the control panel. Using a short piece of conduit (must not exceed 20 feet in length),
connect the control panel to the 5220 Module.
2.
Wire the 5220 to the control panel as shown in Figure 4.28.
This drawing also illustrates how to connect the city box coil to terminals 3 and 4 on the 5220. Do not install an EOL resistor in the
terminals of the NAC circuit used for this application.
3.
Connect the Earth Ground wire to the 5220 chassis with mounting screw.
4.
Program the NAC circuit used as a continuous and non-silencing. Refer to Section 7.5 for point programming, Section 7.4 for group
settings, and Section 7.3 for zone settings and mapping.
It is not possible to reset the remote indication until you clear the condition and reset the control panel
