EQ2200IDCGF SERIES INITIATING DEVICE
CIRCUIT GROUND FAULT
1. Securely mount the aluminum enclosure. The
enclosure should be electrically connected to earth
ground.
2. Connect the external wiring to the appropriate
points on the terminal block. See Figure VII-17 for
terminal block location and Figure VII-19A for
terminal identification.
3. Check all field wiring to ensure that the proper
connections have been made.
4. Install the communication module inside the
junction box. Be sure that the keyed ribbon cable is
properly connected.
5. Set the node address for the device. Refer to
“LON/SLC Device Address Switch Setting” in the
“Switch Setting” section (Section VIII).
6. Inspect the enclosure O-ring to be sure that it is in
good condition and properly installed. Lubricate
the O-ring and the threads of the enclosure cover to
ease both installation and future removal of the
cover. The recommended lubricant is a silicone
free grease available from Detector Electronics. If
the installation uses catalytic type combustible gas
sensors, it is imperative that lubricants containing
silicone not be used, since they will cause
irreversible damage to the sensor. Place the cover
on the enclosure. Tighten only until snug.
Do not
over tighten.
Device Configuration
When configuring the EQ2200IDCGF, its “device type”
should be configured as an initiating device circuit
(IDC).
Both inputs must be configured for a trouble condition.
Circuit 1 – “Open” indicates a –24 VDC ground fault
condition. “Active” indicates a +24 VDC
ground fault condition.
Circuit 2 – “Active” indicates a loss of AC input
power.
“Open” indicates a loss of battery power.
EQ2200IDCSC SERIES INITIATING DEVICE
CIRCUIT SHORT CIRCUIT
The EQ2200IDCSC Initiating Device Circuit Short Circuit
(IDCSC) provides two supervised digital inputs for use
with dry contact inputs from devices such as relays,
pushbuttons, key switches, etc. The IDCSC supports
ANSI/NFPA 72 Class B Style C (3 state, open/short
circuit) supervised input circuits. Each circuit uses its
own end of line (EOL) resistor for monitoring circuit
continuity and a series resistor for each contact.
1. Remove the cover from the junction box.
2. Remove the communication module from the
junction box. Connect external system wiring to the
appropriate terminals on the terminal block inside
the junction box. See Figure VII-17 for terminal
block location and Figure VII-19B for terminal
identification. The input to the IDCSC consists of
one or more normally open switches, with a 10K
ohm, 1/4 watt EOL resistor in parallel across the last
switch. An EOL resistor must be installed on both
IDCSC inputs (including unused inputs). Wiring
impedance must not exceed 500 ohms. A 3.3K
ohm resistor must be installed in series with each
switch.
3. Check the wiring to ensure proper connections.
