Notice
TESTING AND MAINTENANCE OF SYSTEM CONTROLS SHALL BE PERFORMED BY COMPETENT
PERSONNEL HAVING JURISDICTION OVER THIS PROTECTIVE SIGNALING SYSTEM.
TESTING ZONES WITH SOLENOID RELEASE CIRCUITS AND EQUIPMENT SHUTDOWN CONTACTS
MAY BE ACCOMPLISHED BY USE OF A JUMPER WIRE ACROSS EACH DETECTION / INITIATING CIR-
CUIT FIELD WIRING TERMINALS ONLY AFTER THE OUTPUT DISCONNECT SWITCH, LOCATED IN
THE LOWER LEFT CORNER OF MAIN BOARD, HAS BEEN PLACED IN THE LEFT POSITION. SLIDING
THIS SWITCH IN THE LEFT POSITION ALLOWS OUTPUT SIGNALS FOR OP2, OP3, AND OP4 TO BE
BYPASSED.
NOTE: IT IS ALWAYS GOOD PRACTICE TO DISCONNECT ALL PRE-ACTION SYSTEMS PRIOR TO
TESTING.
WARNING!
FATAL ELECTRICAL SHOCK AND EQUIPMENT
DAMAGE MAY RESULT FROM FAILURE TO REMOVE
ALL POWER PRIOR TO SERVICING SYSTEM.
CAUTION
The Protectowire Co., Inc. designs and manufactures fire protection systems to meet both UL and FM
Global criteria for electrical transients introduced on both the power supply side of the system and into the
panel from field wiring for initiating device circuits, notification appliance circuits, and other external field
routed wiring.
Fire protection systems located in areas subject to lightning strikes, or subject to other severe transients,
and electromagnetic interference, should be protected similar to computers and other electronic systems
with supplemental surge and filter protection both on the power supply side and on field wiring for initiat-
ing device circuits, notification appliance circuits and other field routed wiring.
Please refer to surge/filter manufacturers, (eg., DITEK 800-753-2345, www.ditekcorp.com) to specify
devices for your particular conditions. The National Lightning Safety Institute (www. LightningSafety.com)
also provides valuable information regarding the problems and solutions of providing lightning protection
including assuring true earth ground conditions.
Lightning strikes, other severe power surges, and significant EMI/RFI interference, by their nature, are
beyond normal design criteria and are outside the warrantee for manufacturing defects.

Maintenace procedure for complete testing
and operations of installed system.

11
BATTERY CABINET MOUNTING
- The Battery Cabinet should be mounted directly below
the SRP-4x4 Panel. The Battery wiring is classified as Non-
Power-Limited. Therefore the wiring must be segregated
from Power-Limited wiring with a minimum of two cable
entry openings and a 1/4” spacing between the two
conductors.
- Batteries are connected to the Fire Control Panel by using
16 AWG wire to the supplied PWSC splicing connector
(501740) and passed thru closed nipple rigid metal conduit.
- Battery wire leads should be color coded with respect to
supplied battery wiring of the panel.
Caution: Always observe polarity when connecting up
batteries. Improper connection will cause the battery
fuse to blow. See Page 41 for proper Battery Calculation
Sizing.
Caution: Batteries contain sulfuric acid which can cause
severe burns to the skin and eyes. If contact is made
with sulfuric acid, immediately flush skin or eyes with
water for 15 minutes and seek immediate medical
attention.

DRAW SEE APPENDIX A
TABLE 3 - ALARM INDICATING CIRCUIT
WIRE SIZE FOR 24VDC POLARIZING DEVICES
ALARM NOTIFICATION APPLIANCE CIRCUIT WIRE SIZE ESTIMATOR
To insure that all notification appliance circuits will be supplied with adequate power to operate, it is necessary to use
the correct size cable for the distance and current requirements of each circuit. Follow the steps below to calculate the
correct wire size for your application. The calculations are based on a maximum line loss (voltage drop) of 1.0 volts.
1. Calculate the required alarm device current.
(Number of Devices) X (Device Current) = Total Alarm Device Current (AMPS)
2. Determine the wire run distance in feet from the panel to the last alarm device.
3. Find the load current (AMPS) on Table 3 that best matches the required alarm device current. If the device current is
in between two values, use the higher value.
4. Find the wire run distance to the right of the device current value chosen in step 3 which is greater than your
requirement.
5. The gauge at the top of the distance column is what will be required to insure a maximum line loss of less than 1
volt, or 1 ohm max. fully loaded.
EXAMPLE: If the total alarm device load is .680 AMPS; select .750 AMPS. If the measured distance is
400 feet; select 515 feet which is in the 14 AWG column.
TABLE 2 - COPPER WIRE RESISTANCE
NOTE: The maximum alarm indicating circuit resistance is
calculated for a line loss of 1 volt divided by the maximum
alarm device current.

Output circuits OP1 thru OP4 are all power-limited circuits and must be segregated from non-power-limited
circuits with a minimum spacing of two cable entry openings and 1/4” spacing between the two conductor types.
See wire routing detail for layout.
To provide proper supervision of solenoid coils, the ELD must be installed in the same junction box as the
solenoid.
Auxiliary 24 V output is power-limited, with a maximum current draw of 100mA. It is an un-supervised circuit,
therefore it can only be used for three purposes per UL 864 requirements.
NOTES:
1) As a bell, register or similar indicating device included as part of the control-unit assembly.
2) As an alarm bell installed in the same room as the control unit provided the bell circuit conductors are to be
installed in conduit or have equivalent protection.
3) Or as a supplemental signal annunciator, signal-sounding appliance, motor stop, or similar appliance,
provided that neither a short circuit, a break, or a ground fault will not prevent normal operation other than
the omission of the supplementary feature.
Use 10-14 AWG wire, UL listed for application.

PDM-1000-4
PROTECTOWIRE ALARM POINT LOCATION METER
DESCRIPTION:
The PDM-1000-4 PROTECTOWIRE Digital Alarm Point Location Meter is designed to help locate a heat actuated
point on a PROTECTOWIRE line heat detector circuit. This meter identifies the distance in feet or meters (preset
at the factory) along the detector from the start of the run to the actuated point.
Note: The PDM-1000-4 is calibrated at the factory and only requires adjustment to compensate for field cable
resistance at the time of installation.
OPERATION:
When an alarm signal is received at the main control panel, depress the meter switch (see illustration below) of the
zone in alarm. The meter will then display the distance to the actuated portion of the PROTECTOWIRE line heat
detector circuit.
CALIBRATION:
The copper feed wire between the control panel and the zone (junction) box at the start of the PROTECTOWIRE
run has an inherent resistance. This resistance although small compared to that of the PROTECTOWIRE, will
introduce an error in the digital meter reading. The longer the feed wire, the greater the error. Adjust the meter per
the following procedure to compensate for field wiring resistance.
1. Disconnect all alarm and/or releasing devices connected to the control panel
and apply power to the system before proceeding.
2. Connect a jumper wire across the detection circuit at the beginning of the
PROTECTOWIRE run (at the zone box). Caution: This will trip the detec-
tion circuit into an alarm condition.
3. At the control panel press the meter read switch for the appropriate zone in
alarm. The meter will display the feed cable error.
4. To cancel out (zero) this value, adjust the corresponding PT# potentiometer
on the main panel for the zone in alarm by using a small screwdriver to turn
the potentiometer until the meter reads zero (see below).
Note: the positive (+) and negative (-) indicator will fluctuate when zeroed.
5. Repeat this procedure for all other zones containing PROTECTOWIRE
line heat detector.
Note:
The PROTECTOWIRE digital meter is designed for reading lengths of PROTECTOWIRE line heat detector cable
installed at an ambient temperature of 70º F. Since the inner conductors of PROTECTOWIRE consists of two
steel wires, the inherent cable resistance is subject to change proportionally to temperature. For each 10º F change
in temperature a 1% change in total measure cable length can be expected. Using #14 AWG or larger copper feed
wire in detection circuits that have PROTECTOWIRE will minimize meter reading error.

RB-4
AUXILIARY RELAY MODULE
Description - Auxiliary signaling relays are often needed to provide an interface to other systems for annunciation
and/or electrical shutdown. The RB-4 Relay Module provides 4 individually zone activated sets of Form “C”
contacts in one module.
Operation - The RB-4 relays are normally de-energized. Each relay ( 1 – 4) is activated by an alarm of its corre-
sponding input circuit (1 – 4). Indicators L1 through L4 (Red) illuminate when the corresponding relay is activated.

CLASS “A” ALARM NOTIFICATION
APPLIANCE CIRCUIT ADAPTER
Description: The AM-91-2 Alarm Notification Appliance Circuit Adapter Module converts the two Class B system
Alarm Notification Appliance Circuits from the Main Board to Class A type circuits. This provides four wire alarm
notification appliance circuits in lieu of the standard 2 wire circuits.
Operation: The two wire Class B circuits are wired into the module input terminals (TB1). The AM-91-2 then
conditions and converts the circuits to four wire Class A alarm notification appliance circuits. This Alarm notifica-
tion appliance output circuit is fully supervised with the reverse polarity current flow. A short or open in the field
wiring is detected by the system controls. Once an alarm is initiated the circuit immediately reverses polarity and the
24V FWR power is supplied to the alarm notification appliance devices. If a single break occurs in the circuit all
devices will still be supplied power in an alarm state due to the nature of a Class A wiring configuration.
