This instruction manual contains important information on the
installation and operation of supervisory switches. Purchasers
who install supervisory switches for use by others must leave
this manual or a copy of it with the user. These instructions
apply to Safe Signal switches for post indicator and butterfly
type valves. Read all instructions carefully before beginning
installation.
Do NOT use this switch in explosive or potentially explosive
atmospheres. Do NOT leave unused wires exposed.
All supervisory switch installations must comply with local
codes and ordinances and the requirements of the author-
ity having jurisdiction. Additional information is avail-
able in National Fire Protection Association standards NFPA
13, 13D, 13R, 71, and 72. The connection of supervisory
switches to alarm control units is governed by CAN/ULC-
S524-M91, standard for the Installation of Fire Alarm Systems.
General Installation Considerations
1. Model PIBV2A is designed for installation in a
tapped hole and located so that the actuating lever of the
switch engages the target or flag of the valve . The switch
actuating lever is spring loaded against the flag or target of the
valve and is released when the valve moves toward the closed
position from the fully open position. The switch is factory set
to indicate an alarm condition when the target and lever move
in the direction toward the conduit entry hole when the valve
closes, but can be reversed if the installation demands (refer
to Section 4).

an adjustable length actuating lever.
