c. Install the inlet tube (3) by inserting it through the air sampling chamber

as shown in Figure 3. Face sampling tube holes into the air stream

(Figure 4), and secure to the housing with

screws (12).

d. Install the outlet tube (4) by inserting it into the upper socket of the air

sampling chamber with the scarfed end facing downstream (See Figure

4). Secure the bracket to the housing with an

screw.

e. Make sure no sampling holes extend beyond the ductway, that the

stopper (9) remains firmly in position, and that the duct hole is sealed

around the protruding sampling tube.

Air Duct Sampling Tube Pressure Measurement

The

CERBERUS PYROTRONICS

Model PDM-3 Pressure Differential

Measuring device should be used to ensure that the sampling tube pressure

differential is within the specified limits (See

TECHNICAL DATA

). Qualified

personnel should take measurements in accordance with the

PDM-3

Instructions

P/N 315-085535.

ELECTRICAL WIRING

System XL3 -

See Figure 6. Use two wire circuits of 18 AWG, limited

energy, shielded cable without conduit, if permitted by the local building

codes.

MXL Control Panel -

See Figure 7. Use two wire circuits of 18 AWG,

limited energy, shielded cable without conduit, if permitted by the local

building codes.

IXL System (ICON-1) -

See Figure 7. Use two wire circuits of 18 AWG,

limited energy, shielded cable, without conduit if it is permitted by the

local building codes.

Control of Normally Energized and De-Energized Devices

The Model AD-3XRI/3XRILP can be wired for direct relay control of normally

energized and de-energized devices as follows (Refer to Figure 5).
a. Wire normally energized devices (fans, blowers, etc.) to the NC contacts

between terminals 9 and 10 in order to shut down these devices on alarm.

Figure 5

Connections for Control of Normally Energized and De-Energized Devices

NOTES:

1. All relay contacts shown repre-

sent the condition they are in just

after a reset pulse - the normal

supervisory, no alarm condition.

2. If the alarm relay contacts on the

relay board are being used to

control 120 VAC operated equip-

ment, ensure that earth ground

is properly connected to the

internal ground strap, using the

proper conduit lock nuts.

Failure to provide proper

grounding may result in fatal electrical

shock and causes

non-conformance with national

and local codes
