1.5 Loading the Chemcassette
®
Detection Tape
Load a fresh Chemcassette
®
as follows:
1. Open the tape load lever (18).
• The green system status LED (9) will flash
slowly.
• AC Line (1) instruments will display (AC LINE)
on the digital display (19). Battery powered
instruments will display current battery
condition.
2. Remove the center retaining screw securing the
Chemcassette
®
. Remove and discard the old
Chemcassette
®
.
3. Install the fresh Chemcassette
®
(4) with raised
lettering facing up. Pull 30 cm (12 inches) of tape
(7) out of the fresh Chemcassette
®
(4). Place the
end of the tape in the slot on the Chemcassette
®
take-up reel cover (27).
4. Thread the Chemcassette
®
tape (7) through the
detector head (17), capstan assembly (25), and
over the guide posts (5 and 26).
Note:
The EP (30 Day) or XPS (Extended Play)
Chemcassette
®
will lock in position when tape outlet
is at approximately the one o’clock position. The SP
(Standard Play) Chemcassette
®
should be positioned
as shown in the Master SPM Illustration.
5. Install the take-up reel cover (27).
6. Rotate the assembled take-up reel (27) clockwise
to take up any slack.
7. Install the Chemcassette
®
center retaining
screw.
8. Close the tape load lever (18). The SPM will
automatically begin monitoring.
1.6 Monitoring
The SPM is monitoring whenever a Chemcassette
®
(4)
is in place, the tape load lever (18) is closed, and the
power switch (8) on. The green system status LED (9)
will also be lighted.
1.7 Simulating Gas Conditions
The SPM allows two different electronic simulations of
gas conditions: a gross alarm simulation (
Section 1.7.2
)
and a full alarm simulation (
1.7.1 Alarm Relays
Gross alarm simulation and full alarm simulation will
activate the alarm relays. All external devices connected
to the alarm relays will be triggered. To disable relays,
press the relay disable key (14). The relay disable LED
(13) will be lighted whenever the alarm relay contacts
have been disabled.
1.7.2 Gross Alarm Simulation
To make a gross alarm simulation, press the alarm test
key (10). This test activates the audible alarm and lights
the alarm lamp (16). Unless the relay disable key (14)
has been pressed, the gross alarm simulation energizes
the alarm relay contacts. The 4-20 mA output does not
change.
To reset the alarm, press the alarm reset key (11).
