15. SIGNAL ALARM: Audible alarm used to indicate the various types
of alarm conditions which may exist. A continuous alarm is used
for flame out, low sample flow, or in the rare event of detector cell
over-heating. A pulsating alarm is used for indicating the signal level
exceeds the alarm set point.
16. Please use Heath supplied charger only to charge DP4 through this
charger jack.
**NOTE**
The instrument will verify all control switch operations by making a short
beep. This is normal and does not indicate an alarm. Alarms typically last
several seconds or as long as the condition lasts.
B. OPERATING PROCEDURES
The Detecto-Pak 4 is easy to operate. It is important that the following
procedure be carefully read and followed in order to obtain the maximum
benefits of its many features.
**NOTE**
The Detecto-Pak 4 should only be turned on and zero adjusted in a
nonflammable (clean air) atmosphere.
1. Carefully unpack all items from the system carrying case.
2. Always start with a fully charged battery. (See Chapter Four, Section
IV, A-D)
3. Always start with enough fuel in the fuel cylinder to last the expected
operating time. 1,750 psig in the two (2) fuel cylinders will ensure
at least eight hours of operation. Do not allow pressure in the fuel
cylinder to drop below 50 psig.
**NOTE**
Fuel cylinders with negative pressure (vacuum) are supplied on the initial
shipment. The operator must fill cylinders to operating fuel level before
start up of the Detecto-Pak 4.
**NOTE**
Apply a very small amount of supplied “O” ring lubricant to small “O” ring
on the stem of the cylinder valve at least once a week.
