Control Panel Installation
Onboard Relays (Conventional)
Constant Power
Use constant power for applications that require a constant auxiliary power source. Power is always present at Constant circuits.
Resettable Power
Resettable power is typically used to power beam detectors, flame detectors and conventional 4-wire smoke detectors. For circuits selected
as Resettable, 27.4 volt power is always present at the terminals unless a system reset occurs. If a system reset occurs, power is disconnected
from the terminals for 30 seconds, then re-applied.
Sounder Sync Power
Sounder Sync Power continuously outputs the System Sensor synchronization pattern and is intended for use with B200S Series sounder
bases.
4.14 Onboard Relays (Conventional)
The control panel has two built-in programmable relays and a built-in fixed trouble relay. All relays are Form C rated at 2.5 A @ 27.4 VDC
resistive.
4.14.1 Common Trouble Relay
The control panel has a dedicated Form C trouble relay built into terminals labeled TROUBLE. The relay provides a normally open and a
normally closed contact. The trouble relay will deactivate under any trouble condition. Form C rated at 2.5 A @ 27.4 VDC resistive.
4.14.2 Programmable Relays
The control panel has two Form C programmable relays built into terminals labeled RELAY 1 or RELAY 2. Each relay provides a normally
open and a normally closed contact.
To install one or two programmable relays, follow these steps.
1.
Wire Relay 1 and/or Relay 2 as needed for your application. See Figure 4.25 for the location of the relay terminals.
2.
Configure the relay through programming (see ).
4.15 Remote Station Applications
4.15.1 Keltron Model 3158 Installation
The control panel is compatible with Keltron Model 3158, used for direct connection to a Keltron receiver. The 3158 reports alarms, super-
visories, and troubles. The 3158 is intended for connection to a polarity reversal circuit of a remote station receiving unit having compatible
ratings.
Follow the steps for connecting the 3158 to the control panel. Refer to the 3158 installation instructions for complete information.
1.
Wire the 3158 to the control panel as shown in the connection list and Figure 4.26.
2.
Wire the 3158 within 20 feet of the control panel. Wiring must be enclosed in conduit.
3.
Program control panel Relay 2 for alarm.
4.
Program NAC circuit 2 for alarm.
5.
Program NAC circuit 1 for supervisory non-latching

NOTE:
The N.C. contact is the relay contact that is closed when the panel has power and there are no alarm or trouble conditions.
NOTE:
NACs must be programmed for continuous and non-silencing.
