4. Low Battery – Caused by battery voltage being too low or battery failing to pass load test.
Charge or change the batteries.
5. NAC Overload - Caused by exceeding the current rating of one or both of the NAC outputs.
Check for shorts and make sure compatible notification appliances are connected in the
allowable quantities.
6. Program Fail – Caused when the repeater does not acknowledge receipt of a programming
command from the CP-3600(+) facp. Make sure the repeater is turned on and is
communicating with the CP-3600(+).
7. EOL Violation - Caused by an open circuit or short circuit in the NAC wiring or missing TR-3
end of line resistor. The repeater must be able to read the TR-3 end of line resistor. Check for
shorts or opens in the wiring and the presence of the eol resistor.
8. Power Up Reset - Caused when the repeater processor resets its program. This signal is
normal the first time a repeater is powered up. It should not reoccur after the repeater has
power applied. If it does then the repeater requires factory service.
9. Ground Fault* – Caused by the repeater detecting resistance of 1000 ohms or less between
any NAC output line and earth ground. Find the source of resistance and remove it.
10. Hardware Fault – Caused by a fault with the repeaters memory or internal circuitry or SW2 #5
not set correctly. If the switch is set correctly then the repeater will require factory service.

4.2 Outputs
The AR-5 has 1 class A or 2 class B programmable NAC output circuits available. The AR-5 repeater
can also be connected to relay box models RB-10, RB-20, RB-30 and RB-40 via ribbon cable or the
RM-5 relay module can be installed to provide dry closure relays. The RB model relay box can supply
up to 40 programmable N.O. dry contact outputs and the RM-5 provides 5 form C dry contact outputs.
Refer to the relay box section of this manual for further information. All AR-5 NAC and relay output
programming is done at the CP-3600(+) control panel. Refer to the CP-3600(+) control panel manual
for programming options and instructions. Repeater outputs are detailed in the following sections.
Refer to figure 4 for NAC wiring. Wiring diagrams for the RB boxes and RM-5 module can be found in
sections 5 and 6 respectively. All diagrams are shown with A/C and battery power connected with the
repeater in normal operation mode.
4.2.1 Notification Appliance Circuits (TB1 Terminals 1-4)
The AR-5 repeater provides a notification appliance circuit which is field selectable for either 1 Class
A Style Z or 2 Class B Style Y supervised non power limited outputs. Power limited and non-power
limited circuits must be separated by at least .25” within the enclosure and run in separate conduit.
Note: All wiring from the TB1 connector must be run in conduit and contained within one
room. Use minimum 18 awg wire. Refer to figure 3 for suggested wire routing. The outputs are
supervised for wiring integrity and ground fault. The NAC output voltage is 24 Volts D.C. and the
class can be selected with SW3 for either A or B operation as shown in figure 4. The NAC circuit
connector is labeled TB1 and located in the middle of the bottom edge of the repeater board. When
operating on back up batteries the AR-5 will maintain the NAC circuit output voltage within UL limits
until the battery voltage drops below low battery threshold of 20.4 Vdc. The NAC circuits are site
programmable for activation and deactivation through the CP-3600(+) control panel. Refer to the
programming section of the CP-3600(+) manual for complete activation and deactivation
programming options. The circuits utilize current sensing technology and if the rated current draw is
exceeded a NAC overload trouble signal will be displayed on the CP-3600(+) and the NAC circuit will
deactivate. It will attempt to reactivate only if another device sends an alarm or the NAC circuit is
