The 4000 Series Wireless System, an integrated, supervised system for the ZX family of control panels, is new from Sentrol Inc., Tualatin, Ore. It is designed to improve radio frequency (RF) wireless performance and reduce short- and long-term service requirements. Designed to match Sentrol's hard-wired sensors, the RF gateway receiver incorporates internal, dual-diverse antennas that are fully enclosed. Two receivers can be used: the 4720 receiver, which adds up to 16 wireless zones and 12 wireless user devices to the ZX400 controller; and the 4710, which adds up to eight wireless zones and six user devices to the ZX200 controller. The 4000 system includes the model 4110 universal window/door transmitter that uses a magnetic reed switch and magnet for standard door and window applications. The series incorporates Sentrol's detection technologies such as the model 4545 wireless ShatterPro acoustic glass-break detector, which uses an RF transmitter and can be installed on ceilings and walls at a range of 20 feet. The model 4655 wireless Sharpshooter passive infrared detector with transmitter uses digital signal processing and has a range of 45 feet, a selectable pulse count, mounting hardware and seven optional lenses, according to the manufacturer.

The Genesys 824 Fire Package panel accepts two-wire smoke detectors, has eight zones (expandable to 24), two partitions, a 2-amp bell circuit that is expandable to 5 amps, and uses 12 or 24v DC to drive additional horns, strobes and bells. Manufactured by Optex America Inc., Torrance, Calif., the panel includes an LCD alphanumeric keypad, long-range radio compatibility and programmable output terminals.

Two keypads for the Vision Plus burglary and fire alarm system feature elastometric keys and a housing designed to blend with any decor, according to maker Inovonics Corp., Boulder, Colo. The KP103 keypad features an alphanumeric LCD with 2x16-character backlit display and ded-icated "emergency," "fire," "police," "special" and "chime" keys. The keypad, which is hardwired directly to the panel, also includes terminalblocks for splice-free installations and a removable door to protect keys. When installed in conjunction with a speaker or status light, the fully supervised KP103 is a reliable and secure arming, disarming and panic-signaling device, according to the maker. The FA130 features the same housing and keys, but it is designed for wireless installations.

Ease of installation; reduced cost of maintenance, testing and service; virtual elimination of nuisance alarms; configuration options; and up to 250 addressable points are features of the 4010 TrueAlarm Fire Alarm System, according to manufacturer Simplex, Gardner, Mass. The analog system pinpoints alarm locations better than hardwired systems, says Simplex. The device-level, ground-fault search can identify faults at the control panel. Auto programming allows the 4010 to read installed devices and expansion cards and automatically program them for general alarm operation. In addition, Simplex has produced BACpac Portal, a compact panel that enables the company's fire alarm systems to be connected to building automation control networks. The panel enables those responsible for HVAC, lighting control, elevator or security operations to get fire alarm system information at a network station - without running a dedicated network or installing special hardware, drivers or interfaces, says the maker.

The 4042 fire alarm system control panel operates smoke detectors, manual pull stations and water-flow and supervisory switches. Manufactured by Cerberus Pyrotronics, Cedar Knoll, N.J., it features push-button switches for reset, trouble silence, drill test, lamp test, circuit cut-off and history recall. Operator functions are located behind the locked cabinet door. Positive and negative ground-fault detection is provided, and a quick-test feature assists with verifying operation.

The TFX-400 fire alarm control panel is ideal for retrofit installations or for use in small- to mid-size buildings, says maker Grinnell Fire Protection Systems Co., Westlake, Ohio. Housed in a compact cabinet, the unit includes two analog, addressable signaling line circuits that provide 99 points each. The panel has a backlit LCD display and field-configurable LED enunciators, and it can be configured with up to 1,600 discrete contact inputs and voltage outputs in any combination. The TFX-400 system offers a UL-listed alarm verification feature for use with connected circuits of smoke detectors or with Grinnell's 550 series analog, addressable smoke and heat detector, which can compensate for environmental influences. The system supports remote operator control panels, and networking and graphical user interface features. Up to seven remote panels can be connected to the TFX-400, and a virtual front panel feature allows any system panel to be interrogated and controlled from any other panel.

Support up to 127 addressable devices per digital signal line circuit with the Series 3000 analog fire alarm system from Safetech International Inc., Lenexa, Kan. The digital communication protocol provides stability, reduces false alarms, and allows use in retrofit applications using existing wiring, says the maker. The base panel has two digital signal line circuits (expandable to eight) and four outputs that are programmable as notification appliance circuits or auxiliary power outputs. Standard power is 6 amps with 8 amps optional. The system is programmable through the integral keypad, the remote programming display or a Windows 95-compatible PC.
