Pneumatic/Linear Detector Installation
The pneumatic/linear fire detection system, Part No. 416113, is a
Systron Donner Model 808-DRV. This detection system is
completely compatible with the ANSUL CHECKFIRE MP-N control
module.
Each detection system is shipped with a detailed Installation,
Maintenance Manual.
When installing the pneumatic/linear detection system to an
ANSUL CHECKFIRE MP-N control module, use connector/cable
assembly, Part No. 416216, and install per Figure 31.
Note: Attach end-of-line resistor assembly by following the
detailed steps listed on the instruction sheet included with the end-
of-line resistor shipping assembly.

INITIATING INPUT/PRESSURE SWITCH INPUT CIRCUIT NO. 2
The pressure switch feedback function provides a positive feed-
back that a discharge has occurred. It also initiates shutdown
functions and control module alarms regardless of the type of
actuation, either automatic or manual.
Initiating input circuit/pressure switch input circuit must be wired to
Terminals 5 and 6 on the control module terminal strip. The pres-
sure switch circuit must also have an end of line resistor assem-
bly, Part No. 426461, installed in the circuit. See Figure 32.
Note: If pressure switch/electric pull station circuit is not used, a
4.7 k ohms resistor must be connected across terminals 5 and 6
inside the control module.
