1.2 Wiring

1. Zone Wiring

Zones can be wired for Normally Open, Normally Closed Contacts with Single- end-of-line (SEOL) resistors or Double End-of-Line (DEOL) resistors. Observe the following guidelines

•For UL/ULC listed installations use SEOL or DEOL only.

•Minimum 22 AWG wire, maximum 18 AWG

•Do NOT use shielded wire

•Wire run resistance shall not exceed 100Ω. Refer to the chart below.

	Burglary Zone Wiring Chart
Wire	Max wire Length to End-of-line Resistor
Gauge	(feet/meters)
22	3000 / 914
20	4900 / 1493
19	6200 / 1889
18	7800 / 2377

Figures are based on maximum wiring resistance of 100Ω

•Section [009] Selects Hardwired Zone Definition

•Sections [133], [134] Opt [14] selects Normally Closed

•Sections [133], [134] Opt [15] selects SEOL resistors

•Sections [133], [134] Opt [16] selects DEOL resistors.

Zone Status - Loop Resistance/Loop Status

•Fault - 0Ω (shorted wire/loop)

•Secure - 5600Ω (contact closed)

•Tamper - infinite (broken wire, open)

•Violated - 11,200Ω (contact open)

Normally Closed Loops - Do NOT use for UL Installations

2. PGM/Aux Power Wiring

PGMs switch to ground when activated by control panel.

Connect the plus side of the device to be activated to the AUX+ Terminal. Con- nect the minus terminal to the PGM. Each PGM can provide 50mA output.

NOTE: The control panel can provide a maximum of 100mA of AUX current for PGMs, relays, LED’s etc. Min/Max operating voltages for PGMs, relays and modules is 10.2VDC - 13.75VDC

NOTE: Battery Voltage (6.0-8.4VDC) is boosted internally to supply 12VDC on the AUX+ output by setting Sect[014] Opt[4] to ON. This option must be enabled for PGMs used in UL/ULC Residential Burg installations. This output can NOT be used for UL/ULC Fire installations.

3. Telephone Line Wiring

Wire the telephone connection terminals (TIP, Ring, T-1, R-1) to an RJ-31x Connector as indicated. Use 24 AWG wire minimum for wiring.

For connection of multiple devices to the telephone line, wire in the sequence indicated.

Communication format is programmed in section [350]. Telephone Call Directions are programmed in section [351]-[376].

Note: For UL Listed Installations,the Installer must verify the communication format with the supervising station at the time of the installation.

4. Battery 5. AC Wiring

A 1500 mAHr Ni-Mh battery pack is included to meet standby power require- ments

NOTE: UL/ULC Residential Burglary installations require 4 Hr. power standby time plus 4 minutes alarm annunciation.

NOTE: UL/ULC Residential Fire installations require 24 Hr. power standby plus 5 minutes alarm annunciation

NOTE: Battery life is 4-5 years under typical operating conditions. Battery capacity deteriorates with age and number of charge/discharge cycles. Replace battery every 4-5 years.

AC Transformer Requirements:

Primary:120VAC, 50/60Hz., 0.33A

240VAC, 50/60Hz., 0.165A Secondary: 16.5VAC/20VA

The following Transformers shall be used:

UL Listed Installations - PTD1620U, PTD1640U (60Hz.) ULC Listed installations - PTD1620, PTD1640 (60Hz.) EU Installations - PTD1620T-EU (50 Hz.)
