High Security Alarm Monitoring

Hirsch uses very stable digitally

processed analog inputs with 2% line

supervision for high security alarm

monitoring. A line supervision module

(DTLM, MELM, or SBMS) is located

at the door contact, alarm sensor,

request to exit (RQE), or similar device

to establish this supervision.

In lieu of “shunting,” which turns off

supervision, Hirsch uses “alarm mask-

ing” for full-time supervision and

reporting of line status –– even during

hours of authorized access. Conditions

reported include: Alarm, Secure, RQE,

Mask, Tamper Alarm, Tamper Secure,

Short, Open, Noisy and Input-Out-of-

Spec.

Relay Control System

Relay outputs on DIGI*TRAC con-

trollers can be used for: electric door

locks and strikes, arming/disarming

security systems, alarm annunciation,

elevator floor control, HVAC control,

lighting control, storage locker control,

and many other equipment control

applications. These relays may be acti-

vated by codes (via ScramblePad),

cards (via MATCH and reader), time

zones, alarms, or logic sequences

linked to other relays.

When used with a ScramblePad,

DIGI*TRAC controllers are ideal for

after-hours tenant override systems.

A history of who issued the override

command is available for tenant billing

or audit trails.

Programmer’s Terminal

DIGI*TRAC controllers can be pro-

grammed by either a ScramblePad or a

PC using Hirsch Host software. The

PC can be local or connected by LAN

or modem. A ScramblePad used for a

local control can also be used as a pro-

grammer’s terminal. Programming

functions supported include: add &

delete user access codes, assign

unlock/relock codes, assign alarm

codes, and assign elevator control

codes.

SCRAMBLE*NET

DIGI*TRAC controllers communicate

with a Hirsch Host PC using SCRAM-

BLE*NET protocol which uses an

encryption algorithm for high security.

The SCRAMBLE*NET command/

packet structure is ideal for LAN and

hardwired paths, including RS-485

multi-drop and RS-232 via direct con-

nect or dial-up modem.

Reliability By Design

DIGI*TRAC Controllers are designed

for “high availability” as complete sys-

tems solutions for global markets.

Standby batteries for both memory and

system operation are standard. The

controller ships with an internal inter-

national power supply. All Keypad/

Reader terminals and power circuits

are fused. Each unit is configured in a

heavy duty, NEMA-style enclosure,

with a high security lock and tamper

alarm.
